Precautions
• Any command of G.INPUT cannot be pulse converted.
• G.INPUT must be executed while the I/O signal read request signal is on.
• The following table summarizes the processes that take place if another instruction is issued while the G.INPUT instruction
is active or the G.INPUT 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.INPUT 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.INPUT
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.

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