HTiming of Message Response Reading

Responses are read when the Message Communications Enabled Flag turns ON in the next cycle. The Message Communications Enabled Flag will turn OFF when a Master Unit is executing message com- munications. If the message response is faster than the PC ladder program cycle time, the Message Communications Enabled Flag will remain ON and response processing will not be possible. Execute the read response processing before IOWR, as shown in the following diagram, and produce a Mes- sage Communications Status Flag (d) using bit A.

Note If the read response processing is executed after IOWR, there can be no Message Communica- tions Enabled Flag response by means of IOWR, so an attempt could be made to read the re- sponse even though the message communications have not been completed.

	Flag	Functions

	Equals Flag (SR 25506)	The Equals Flag turns OFF when an error occurs in writing a command
		from the CPU Unit to the Master Unit.
		This Flag turns ON after a command has been written normally from the
		CPU Unit to the Master Unit.

	Error Flag (SR25503)	The Error Flag is OFF when all operands and the control code are legal.
		This Flag turns ON when an illegal operand or control code is set or
		when there is an error in instruction execution.

	Message Communications	The Communications Enabled Flag turns OFF during messages
