Important Product Information
Enable Break-Free SNP Slave Operation COMMREQ: 7005
Available Modes: Slave
Local command. This command enables the break-free SNP feature in IC693-30 CPU firmware version
8.20 and later. See command 7004 for a discussion of break-free SNP.
Because break-free operation is enabled when the PLC is powered on, this command has no effect
unless command 7004 was previously executed. If a communication session is in progress when this
command is executed, communication will continue, and detection of no-break Attach/X-Attach
messages will begin when the current session is ended by a link-idle time-out.
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
