7.4 Communication using intelligent function module dedicated instructions
Intelligent function module dedicated instruction is an instruction for realizing easy
programming to use the functions of intelligent function modules.
Some intelligent function module dedicated instructions can specify a completion
device.
The completion device turns ON for one scan after the instruction execution is
completed.
If multiple intelligent function module dedicated instructions are used for the same
intelligent function module, create a program so that dedicated instructions are
executed one by one, following the completion device of each instruction tuning ON.
(a) Changing the operation status before the completion device turns ON
f the operation status of the CPU module is switched from RUN to STOP before
the completion device turns ON after an intelligent function module dedicated
instruction execution, the completion device turns ON after the status is switched
to RUN again and the operation is performed for one scan.
(b) Supported instructions
For instructions supported in the safety CPU module, refer to Appendix 7.
Remark
For details on intelligent function module dedicated instructions and completion
devices, refer to the manual of an intelligent function module used.
