Precautions
• The following table summarizes the processes that take place if another instruction is issued while the G(P).OUTPUT
instruction is active or the G(P).OUTPUT instruction is issued while another instruction is active with the same channel.

*2 The following instructions are not available with the same channel as for the G(P).OUTPUT 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
G(P).OUTPUT instruction, a communication protocol setting error (7FF2H) will occur.
• G(P).ONDEMAND, 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.

Handling for concurrent execution
The instruction is ignored and does not start processing until the active instruction
completes.
Concurrent execution is, however, possible if they use different channels.
