Product Manual Excerpt

December 3, 1999 GFK-1126Z IMPORTANT PRODUCT INFORMATION READ THIS INFORMATION FIRST Product: IC693 CPU Modules with Firmware Release 9.10 IC693CPU352-DJ IC693CPU363-AD Introduction This document contains information that is not available in any other publication; therefore, we recommend you save it for future reference. This document discusses the features of firmware release 10.00 for CPU modules IC693CPU352 and IC693CPU363. Feature Highlights of Firmware Release 10.00 for CPU352 and CPU363 Note: The following CPU features will be documented in VersaPro 1.1 (when released) on-line help. 1. Support was added for the IC693DSM314 servo module. 2. Add support for storing Local Logic Programs. These programs are stored to the CPU from the programmer (VersaPro 1.1 is required to use this feature). These programs will automatically be stored from the CPU to the appropriate smart option module. The limit on the size of all Local Logic Programs is 65280 bytes. 3. Reboot after Fatal Fault – This option will enable the IC693 PLC system to automatically resume normal operation after a fatal fault has occurred. Following the fatal fault, the PLC will automatically reset and resume execution. If fatal faults are present following the power up, the PLC will still be allowed to transition to run mode. The user can enable this feature through a configuration parameter, and can identify the maximum number of retries and the time period these retries may occur within through new Service Request #48. New Service Request 49 may then be used to determine the number of fatal faults and retries that have occurred. This feature requires VersaPro 1.1 to configure. 4. Addition of the Drum Sequencer function block. This function block operates in the same manner as it does on the IC200 CPU. VersaPro 1.1 is required to use this feature. Feature Highlights of Previous Release 9.00 The following features were introduced in release 9.00. • Software Floating-Point. The CPU363 supports all of the floating-point function blocks that are currently supported by the CPU352. They are implemented in firmware using floating point emulation. These FloatingPoint math function blocks are described in the IC693 PLC Reference Manual. The CPU352 continues to support Floating-Point math via its built-in math coprocessor. The CPU352 offers a speed advantage for performing math functions when compared with the CPUs (such as CPU363) that use firmware-based floating-point math. • User memory totals 240K bytes. %R, %AI, and %AQ references are configurable up to 16K of %R, 8K of %AI and 8K of %AQ memory using the MS-DOS PLC programming software, version 9.02. These three references are configurable up to 32K in version 2.2 of the Windows® PLC programming software and version 1.0 of the VersaPro programming software. Configuration instructions for this feature are described in the MS-DOS IC693 Programming Software User’s Manual, and are included in on-line help in both Windows PLC programming software packages.  MS-DOS and Windows are registered trademarks of Microsoft Corporation 2 Important Product Information GFK-1126Z • Sequential Event Recorder. The Sequential Event Recorder function block can be used to record up to 1024 samples of 32 individual discrete (bit) references. This function block is described in the IC693 PLC Reference Manual and in online help for the Windows programming software. • Break-free SNP. The SNP protocol no longer requires a break to operate. This allows SNP to work over a wider variety of modems. Hardware Identification The following table shows the revision level of the circuit boards used in the current versions of these CPUs.

All previous versions are capable of being upgraded. Firmware Upgrade Kit Catalog Number CPU Catalog Number Firmware Upgrade Kit Catalog Number IC693CPU352 - (all versions) 44A739385-G07 IC693CPU363 - (all versions) 44A747766-G03 Firmware Identification CPU Catalog Number Motherboard Firmware Version Daughterboard Firmware Version IC693CPU352-DI Main: R10.10 (47A1) Boot: R9.00 (33A1) Main: R10.01 (49A1) Boot: R1.00 (12A2) IC693CPU363-AD Main: R10.10 (47A1) Boot: R9.00 (33A1) Main: R10.01 (49A1) Boot: R2.00 (30A1) Functional Compatibility • VersaPro version 1.1 or later is required to utilize the features introduced in release 10.00 firmware. • The Windows PLC Programming Software version 2.00 or later must be used to take advantage of C programming or Sequential Function Chart (SFC) subroutines. • Version 4.00 or later of the C toolkit must be used for C programming. • The MS-DOS PLC Programming Software Version 9.02 or later must be used to take advantage of the features introduced in firmware release 9.00. These features are listed in the section “Feature Highlights of Previous Important Product Information 3 GFK-1126Z Release 9.00.” Note that the CPU363 can be configured with the MS-DOS PLC Programming Software Version 9.01, but only features prior to firmware release 9.00 are supported in that software version. Operating Notes User Flash Contents User information, consisting of program, configuration, CPU ID (used for SNP communications), and status tables in RAM memory, will automatically be cleared if the CPU firmware in flash memory is changed. You will need to restore these if upgrading firmware. A recommended procedure is to first back up your user information from RAM memory to Flash memory. Then write your new firmware to Flash memory (firmware is stored in a different location in Flash memory than that used for storing user information such as program, configuration, etc.). Finally, write your user information back out of Flash into RAM memory. As an alternative, your user information (program, configuration, etc.) can be restored from a computer-based backup program folder using your PLC programming software. The SNP ID must be set separately, using the programming software or the Hand-Held Programmer (HHP). Firmware Upgrade Procedure Note: The Model 352 and 363 CPUs’ operating firmware is stored in FLASH memory. The firmware upgrade is provided on a floppy disk and must be serially downloaded from a Personal Computer. An IBM AT personal computer or better PC with a minimum 640K of RAM, one 3.5” floppy drive, MS-DOS version 3.3 or later (or Windows 95 or later), a hard drive, and one RS-232 serial port is required. In addition, a serial cable is required. The following serial cable kit is available: IC690ACC901 Mini Converter Kit with cable (RS-232/RS-485) Changing Firmware to an Earlier Version If you have a CPU352 with firmware version 9.00 or later, and you want to install a pre-9.00 version of firmware, a special upgrade disk must be obtained from your distributor. Do not attempt to use a firmware version 8.10 or earlier upgrade disk on a CPU that contains firmware version 9.00 or later. Note that pre-9.00 firmware versions do not support the CPU363. Option Module Revision Requirements • Ethernet Interface Module Compatibility. All IC693 Ethernet Interface (IC693CMM321) modules used with these CPUs should be updated to IC693CMM321 firmware release 1.10 or later. This is also a requirement of the TCP/IP Ethernet version of the MS-DOS programming software. During a Run Mode Store (Alt + S hot key combination) of a large program block (greater than 14 kilobytes), the Ethernet module may time out, causing communications to fail. Changing the Communications Window to Run-to-Completion mode, or storing the program in Stop mode, will allow the store to take place successfully. • FBC Compatibility. FBC version 3 or later is required for these CPUs. • GCM Compatibility. Fab board R08 or later of the IC693CMM301 should be used with the CPU352. Writing Flash Using a Serial Programmer When writing very large programs to flash memory, it may be necessary to increase the Windows PLC programming software request timeout value to avoid receiving a request timeout message. An upper bound of 25 seconds is typically satisfactory. Storing Large Configurations The IC693 PLCwill normally support 20 DSM314 modules in a system. This number may be reduced by other modules in the system, such as APM and GBC modules. It may also be further reduced by having datagrams set up which will read the reference or fault tables. If the configuration and user program is stored at the same time, the presence of either 4 Important Product Information GFK-1126Z C blocks within the LD program, or a C logic program may also affect the number of DSM314 modules which may be included in a system. If the store fails, it may be possible to store the configuration to the system by first storing the logic program, and then storing the configuration on a separate store request. The number of modules supported may be further reduced by the memory available to the user. Problems Resolved in Firmware Version 9.10 AI & AQ Above Default Values Release 9.00 provided support for configuring %AI and %AQ above their default values. These new references would previously only work as extra program memory, and could not be used as actual inputs or outputs on physical modules in the configuration. This has been corrected in release 9.10 so that these higher references will now work the same as the lower references. CPUs 352 and 363 Embedded Serial Ports with Version 9.00 and 9.01 Firmware The embedded serial ports on the PLC CPU (ports 1 and 2) would not function with release 9.00 or 9.01 if 34 or more rack mounted modules were being used in the system. The problem could also occur if any IC693PCM300, 301, 311, IC693CMM311, or IC693ADC311 modules were used. The serial port on the power supply was not affected. This restriction has been corrected in release 9.10 to allow use of the extra ports with the maximum number and types of modules. Load File of Size 1528 Bytes Loads of a user program where the file was of this specific size would fail. This has been corrected in release 9.10. C Program with Code Area Greater Than 64K Bytes Before release 9.10, C Program blocks with code areas greater than 64k bytes would not store. In release 9.10 and later, ‘C’ program blocks code sizes are limited only by available memory. Problems Resolved in Firmware Release 10.00 User Flash Write and Erase Failure User Flash Write/Erase operations were failing when the Flash Memory was subjected to significant temperature variations. This failure is now detected correctly, an error message is displayed to the user, and the user can retry the operation. IC693 PLC can Automatically go to run Mode. The IC693 PLC could automatically go to run mode if a configuration enabling the keyswitch is stored to a PLC with the keyswitch in the ON position whose initial configuration had disabled the keyswitch. Retentive Contact Previous Values Table not Being Cleared The previous values tables for retentive contacts was not being cleared out on a Stop to Run transition Problems Resolved in Firmware Version 9.01 SNP Master mode on CPU Ports With some very large configurations and version 9.00 firmware, after a power-cycle, CPU ports set up for SNP Master would need to have their configuration re-stored for the protocol to accept COMM_REQs. This is corrected in version 9.01. Important Product Information 5 GFK-1126Z Online Changes to Reference Tables Making online changes with the programmer to reference tables could result in a watchdog timeout. This has been corrected in version 9.01. Read from Flash In version 9.00, reading a folder from flash memory could result in the PLC going into a faulted state. This is corrected in version 9.01. Restrictions and Open Issues Timing Issue With ALG220/221 Modules May Result in Incorrect %AI Values Read by CPU A problem was found with the IC693ALG220/221 where the actual %AI values reported by the card may exhibit erratic behavior (catalog module revisions F and earlier may show this problem; revision G has fixed this problem). Certain current or voltage levels within the input range applied to the card could cause the %AI values to report incorrectly. The problem stems from the use of particular optocouplers, which may exhibit timing issues with these CPU35x/36x modules. CPUs 341, 331, 321, 313, and 311 have not exhibited this timing problem reading %AI values. The IC693 PLC will generate a fatal fault if a ladder containing DOIO function block calls to a smart module is repeatedly placed in RUN then STOP mode A problem was found with the CPU where a ladder containing a call to a DOIO function block will cause the PLC to run out of system memory. This is caused when the PLC transitions to run mode and back to stop mode several times. If the configuration is stored, the system memory will be freed, and the PLC will resume normal operation. Time of Day Clock may not Operate at Power-up This would result in a Fatal PLC CPU HW FAULT being logged. Shorting the supercap will restore the board to normal operation. IC693 PLC CPU may Develop Fatal Fault During Store of Folders with Large Configurations The IC693 PLC CPU may generate a fatal fault during a store of a folder with an especially large configuration. This may be made worse by storing a program and configuration at the same time, or by having datagrams from a programmer present during the store. Rotate Right and Rotate Left functions do not handle error condition The Rotate Right and Rotate Left functions do not correctly handle rotating a string with a rotation request greater than 16 times the length (in words) or the array. These functions should only be used with the rotation request less than 16 times the length (in words) of the array. PID Integral Contribution The PID Integral Contribution is not calculated correctly with an integral rate of 0 or 1. A CPU360 Configuration Stored to CPU352 may Cause Fatal Fault If a CPU360 configuration file is stored to a CPU352, the PLC may generate a fatal fault when transitioning to run mode. Reading from an Invalid Flash Part may Cause a Watch Dog Timeout If a corrupted flash part is read, the Watch Dog Timer on the PLC may be triggered. This can be fixed by completing a valid flash store. 6 Important Product Information GFK-1126Z Fatal Fault Occurs when Configuring a Module with the HHP Following a Maximum Size PLC Store The IC693 PLC CPU may generate a fatal fault while attempting to configure a module with the Hand-Held Programmer following a maximum size store to the PLC. Firmware Update Fail Following Power-up with Clear M/T and a Write to Flash Firmware update may fail following a power-up with Clear M/T pressed on the HHP and a write to flash. Cycling power on the PLC will enable the upgrade to proceed. Changes to Documentation The IC69* PLC Serial Communications User’s Manual will be updated to describe the Serial I/O and pager enunciation feature in its next revision (rev. D). These features are supported by the 352 and 363 CPUs’ embedded serial ports (Ports 1 and 2, located on the module faceplate), but are not supported on the serial port (Port 3) that uses the connector on the PLC power supply. The information in this section applies to the write output function of the Serial I/O feature (which was added in an earlier release). Information on the read input function, added in firmware release 10.00, will be included later in a manual update early in the year 2000. Sending a COMM_REQ to CPU352 or CPU363 Serial Ports 1 and 2. When sending a Communications Request (COMM_REQ) to the CPU352 or CPU363 serial ports, the SYSID of the COMM_REQ must be 1 and the TASK ID must be 19 decimal for Port 1 or 20 decimal for Port 2. RTU With the above exception about the SYSID and TASK ID fields, using RTU on the CPU352 or CPU363 serial ports is the same as using RTU on a CCM, which is described in the IC69* PLC Serial Communications User’s Manual. Serial I/O Write Serial I/O write is selected for Port 1 or Port 2 of the CPU352 or CPU363 CPUs by choosing “CUSTOM” as the mode for the port in the CPU Configuration and storing this to the PLC. Generic Output is accomplished by using the put string COMM_REQ. Using the autodial COMM_REQ with the put string COMM_REQ accomplishes the pager enunciation feature as described below. Using Pager Enunciation and Serial I/O Write This feature allows the 352 and 363 CPUs to automatically dial a pager via modem and send a specified byte string from Serial Port 1 or 2. Pager dialing and message transmission are set up by COMM_REQ functions in the ladder logic. Note To implement this feature, Serial Port 2 must be configured as a CUSTOM port as mentioned above in the “Serial I/O Write” item. Pager enunciation is implemented by three commands, requiring three COMM_REQ command blocks: Autodial: 04400 (1130H) -Dials the modem. This command works the same way that the SNP Master Autodial command 7400 does. Put string: 04401 (1131H) - Specifies an ASCII string, from 1 to 250 bytes in length, to send from the serial port. Autodial: 04400 (1130H) - It is the responsibility of the PLC application program to hang up the phone connection. This is accomplished by reissuing the autodial command and sending the hang-up command string. Important Product Information 7 GFK-1126Z Autodial Command Block The Autodial command automatically transmits an Escape sequence that follows the Hayes convention. If you are using a modem that does not support the Hayes convention, you may be able to use the Put String command to dial the modem. Examples of commonly used command strings for Hayes-compatible modems are listed below: Command String Length Function ATDP15035559999 16 (10H) Pulse dial the number 1-503-555-9999 ATDT15035559999 16 (10H) Tone dial the number 1-503-555-9999 ATDT9,15035559999 18 (10H) Tone dial using outside line with pause ATH0 5 (05H) Hang up the phone ATZ 4 (04H) Restore modem configuration to internally saved values Table 6-1 lists a sample COMM_REQ command block that dials the number 234-5678 using a Hayes-compatible modem. Table 6-1. Sample Command Block for Serial I/O Autodial Command Word Definition Values 1 0009H CUSTOM data block length (includes command string) 2 0000H NOWAIT mode 3 0008H Status word memory type (%R) 4 0000H Status word address minus 1 (Register 1) 5 0000H not used 6 0000H not used 7 04400 command (1130H) Autodial command number 8 00030 (0001H) Modem response timeout (30 seconds) 9 0012 (000CH) Number of bytes in command string 10 5441H A (41H), T (54H) 11 5444H D (44H), T (54H) 12 3332H Phone number: 2 (32H), 3 (33H) 13 3534H 4 (34H), 5 (35H) 14 3736H 6 (36H), 7 (37H) 15 0D38H 8 (38H) (0DH) Put String Command Block Table 6-2 lists a sample COMM_REQ command block that sends the data string, “hello world” using the Put String command (04401). A maximum transmit timeout of 30 seconds is specified. The string data begins at Word 10. This command is similar to the Autodial command except that Put String does not send the escape sequence for Hayescompatible modems. The Maximum Transmit Timeout field specifies, in seconds, the maximum time interval the COMM_REQ will wait for the entire string to be sent. If this time is set to 0, a default value of 4 seconds plus the time required to transmit the number of characters is used. If the string is not transmitted during the specified interval or the default interval, an error code is generated. 8 Important Product Information GFK-1126Z The Number of Bytes in Command String field specifies the length of the command string to be sent. This length includes all characters. A status code indicating successful transmission will be returned when the string has been completely sent out the serial port. Table 6-2. Sample Command Block for Put String Command Word Definition Values 1 0009H CUSTOM data block length (includes command string) 2 0000H NOWAIT mode 3 0008H Status word memory type (%R) 4 0000H Status word address minus 1 (Register 1) 5 0000H not used 6 0000H not used 7 04401 command (1131H) Put String command number 8 001EH Maximum transmit timeout (30 seconds) 9 000BH Number of bytes in command string 10 6568H h (68H), e (65H) 11 6C6CH l (6CH), l (6CH) 12 206FH o (6F), “ “ (20H) 13 6F77H w (77H), o (6FH) 14 6C72H r (72H), l (6CH) 15 0064H d (64H) Important Product Information 9 GFK-1126Z Status Word for Serial I/O COMM_REQs A value of 1 will be returned in the COMM_REQ status word upon successful completion of a Serial I/O command. Any other value returned in the COMM_REQ status word is an error code where the low byte is a major error code and the high byte is a minor error code. Table 6-3. Status Codes for Serial I/O COMM_REQ Major Status Code Description 1 (01H) Successful Completion (this is the expected completion value in the COMM_REQ status word). 12 (0CH) Local CSTM_PROT error — Port configuration command 65520 (FFF0H). An error occurred while processing a local command. The minor error code identifies the specific error. 2 (02H) COMM_REQ command is not supported. 13 (0DH) Remote CSTM_PROT error — Put String command 4401 (1131H). An error occurred while processing a remote command. The minor error code identifies the specific error. 2 (02H) String length exceeds end of reference memory type. 3 (03H) COMM_REQ data block length is too small. String data is missing or incomplete. 48 (30H) Serial output timeout. The serial port was unable to transmit the string. (Could be due to missing CTS signal when the serial port is configured to use hardware flow control.) 50 (32h) COMM_REQ timeout. The COMM_REQ did not complete within a 20-second time limit. 14 (0EH) Autodial Error — Autodial command 4400 (1130). An error occurred while attempting to send a command string to an attached external modem. The minor error code identifies the specific error. 1 (01H) Not used. 2 (02H) The modem command string length exceeds end of reference memory type. 3 (03H) COMM_REQ Data Block Length is too small.
