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.
*1 The G(P).CPRTCL instruction is not available with the same channel as for the Z(P).CSET instruction because it uses a communication
protocol different from the one used by the ZP.CSET instruction. If the above instruction is used with the same channel as for the
G(P).CPRTCL instruction, a communication protocol setting error (7FF2H) will occur.
• The local device and the file register for each program are not available for setting data.
Operation error

Possibility of
concurrent execution
Handling for concurrent execution
G(P).ONDEMAND  A dedicated instruction concurrent execution error (7FF0H) occurs in the second
instruction.
Concurrent execution is, however, possible if they use different channels.
G(P).OUTPUT
G(P).PRR
G(P).BIDOUT
G(P).BIDIN
G.INPUT 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.
ZP.CSET  The instruction is ignored and does not start processing until the active instruction
completes.
Concurrent execution is, however, possible if they use different channels.
G(P).PUTE 
G(P).GETE
Z.BUFRCVS
G(P).SPBUSY
ZP.UINI  A dedicated instruction concurrent execution error (7FF0H) occurs in the second
instruction.
