(7) When the programmable controller CPU monitoring registration is performed,
the corresponding interface data communication protocol setting is only
designated when non procedure protocol is used for the following data for
designation in the control data.
• User frame output head pointer for constant cycle sending/ batch conditions sending.
• User frame transmission count for constant cycle sending/ batch conditions sending.
When the communication protocol setting for the corresponding interface is MC protocol, there is no need to
designate the user frame output head pointer and the user frame transmission count.
(It is ignored when being designated.)
(8) Simultaneous execution of dedicated instructions
The following table lists the handling for when executing another instruction during execution of the CSET
instruction or executing the CSET instruction during execution of another instruction in the same channel.
: Available, : Not available
*1 Because the dedicated instructions listed below use a different communication protocol from that for the CSET
instruction (programmable controller CPU Monitoring Register/Cancel), they are not used in the same channel.
• BIDOUT, BIDIN
•CPRTCL
If the dedicated instructions above are used in the same channel with the CSET instruction, the communication protocol
setting error (7FF2H) occurs.
