Product Manual Excerpt

GFK-0561U August 2, 2004 I MPORTANT P RODUCT I NFORMATION READ THIS INFORMATION FIRST Product: Communications Coprocessor IC693CMM311P with Firmware Version 4.3 Note: This document contains information that is not available in any other publication; therefore, we recommend you save it for future reference. Please read this document before installing or attempting to use the module listed above. This version of IC693CMM311 firmware corrects a problem in the SNP protocol. Refer to “Problems Resolved by this Version” for details. Update Strategy The problem correction in this release is available to users of IC693CMM311N and earlier versions by installing the upgrade kit, 44A731229-G10. The kit contains a new PROM and must be ordered from the factory. Product Documentatation Important Product Information (this document), GFK-0561U Series 90 PLC Serial Communications User’s Manual , GFK-0582 Data Sheet included in Series 90-30 Programmable Controller Installation and Hardware Manual , GFK-0356 Functional Compatibility Subject Description PLC CPU Compatibility Series 90-30 PLC CPU firmware release 4 or later is required to use the SNP Update Real Time Datagram Service. Programmer Version Requirements Proficy™ Machine Edition Logic Developer version 2.60 or later, VersaPro™ version 2.03 or later, CIMPLICITY Control version 2.50 or later, or Logicmaster Release 3 or later is required to configure the IC693CMM311 Problems Resolved by this Version Subject Description SNP and SNP-X ignore Attach messages when the CPU has a level 2 password. In previous firmware versions, the SNP and SNP-X protocols ignore Attach messages when the PLC CPU has a password at privilege level 2. In version 4.3, SNP and SNP-X masters are able to attach and obtain read-only access to PLC data when there is a level 2 password. SNP masters are not permitted to obtain write access to PLC data by using the correct password. If there is a level 2 password, the PLC CPU posts an Invalid Password fault in the PLC fault table whenever 1) an IC693CMM311 powers on or resets, 2) an IC693CMM311 receives an Attach or X-Attach message from an SNP or SNP-X master, or 3) an SNP master connected to an IC693CMM311 attempts to use a valid or invalid password. 2 Important Product Information GFK-0561U Restrictions and Open Issues Subject Description CMM Data Rate Recoverable CMM communication errors, such as dropped characters, may occur when the CMM operates both ports simultaneously at data rates above 9600 bps. It is recommended that the data rate on either CMM port not exceed 9600 bps when using both ports simultaneously. SNP/SNP-X protocols do not support two-wire RS-485 operation While both the RTU and CCM protocols do support a two-wire RS-485 operation, SNP/SNPX do not. Only four-wire RS-485 operation is supported. WAIT Mode CCM COMREQ Programming a CCM COMREQ command for WAIT mode will degrade the PLC sweep time and may halt the PLC CPU, turning off its OK LED. Do not use WAIT mode COMMREQs unless you have a compelling reason. If WAIT mode is used, it is absolutely essential that no COMMREQs are sent until the CMM is ready to accept them, and that the sum of the worst-case PLC sweep time (without sending a COMREQ) plus the longer of the two COMREQ time-out values is less than the PLC CPU watchdog timer setting. If two or more WAIT mode COMMREQs can be sent during the same PLC sweep, the total of the time-outs for all COMMREQs must be considered. The SNP and SNP-X protocols do not support WAIT mode COMMREQs. CCM Time-out with SHORT config value When the CCM “Timeout” configuration parameter is set to SHORT, CCM data transfer may time-out if the PLC scan is longer than 10 milliseconds. It is recommended that the Timeout configuration parameter be set to MEDIUM or LONG
