Precautions
• The following table summarizes the processes that take place if another instruction is issued while the ZP.CSET instruction
is active or the ZP.CSET instruction is issued while another instruction is active with the same channel.
Instruction to execute
*1
concurrently
G(P).ONDEMAND
G(P).OUTPUT
G(P).PRR
G(P).BIDOUT
G(P).BIDIN
G.INPUT
ZP.CSET
G(P).PUTE
G(P).GETE
Z.BUFRCVS
G(P).SPBUSY
ZP.UINI
*1 The following instructions are not available with the same channel as for the ZP.CSET instruction because they use a communication
protocol different from the one used by this instruction. In addition, if these are used with the same channel as for the ZP.CSET
instruction, a communication protocol setting error (7FF2H) will occur.
• G(P).CPRTCL, G(P).BIDOUT, and G(P).BIDIN instructions
• The local device and the file register for each program are not available for setting data.
Operation error
Error code Description
((s2)+1)
 MELSEC iQ-R Serial Communication Module User's Manual (Application)
7000H to 7FFFH
The programmable controller CPU monitoring settings (control data (s2)+13 to (s2)+102) are checked, not when the CSET
instruction is executed, when the specified cycle time has elapsed.
If the CSET instruction is completed successfully and the registered monitoring data is not sent from the serial communication
module within the specified cycle time, check the programmable controller CPU monitoring function execution results (buffer
memory address: 2205H/2305H) to check for errors and troubleshoot.
Possibility of Handling for concurrent execution
concurrent execution

A dedicated instruction concurrent execution error (7FF0H) occurs in the second
instruction.
Concurrent execution is, however, possible if they use different channels.
See the right • If the G.INPUT and ZP.CSET instructions are issued in this order
A dedicated instruction concurrent execution error (7FF0H) occurs in the ZP.CSET
instruction.
Concurrent execution is, however, possible if they use different channels.
• If the ZP.CSET and G.INPUT instructions are issued in this order
Concurrent execution is possible.

The instruction is ignored and does not start processing until the active instruction
completes.
Concurrent execution is, however, possible if they use different channels.


A dedicated instruction concurrent execution error (7FF0H) occurs in the second
instruction.
