Product Manual Excerpt

Additions to User Manual The following will be added to the IC69* PLC Serial Communications User’s Manual at its next revision (version E): Disable Break-Free SNP Slave Operation COMMREQ: 7004 Available Modes: Slave Description: Local command. This command disables the break-free SNP feature in IC693 CPU firmware version 8.20 and later versions. Break-free SNP simplifies MODEM communication with IC693 PLCs by eliminating the requirement for a serial break at the start of each SNP and SNP-X session. Break-free SNP on built-in slave ports in PLC CPUs uses a small fraction of the CPU processing bandwidth. For most applications the impact on CPU performance is negligible. However, applications that use multi-drop SNP or SNP-X communication can incur noticeable increases in PLC sweep times because all slave units must examine every received message. This command disables break-free operation and eliminates its impact on PLC sweep time. Break-free operation remains disabled until the next time the PLC is powered on or command 7005 is executed. If a communication session is in progress when the command is executed, communication will continue, but detection of no-break Attach/X-Attach messages will stop immediately. The COMMREQ that sends this command may be executed on the first PLC sweep. If the COMM_REQ status word location specified in words 3 and 4 of the command block is not a valid %R, %AI or %AQ reference, power flow into the COMM_REQ function block will cause power flow to its fault (FT) output. Otherwise, the value one (1) is written to the status word when the command succeeds. When unsuccessful, one of these values is returned:
