19 CC-LINK INSTRUCTIONS
19.8 Performing a Message Transmission to a Remote Device Station
• The G(P).RDMSG instruction can be simultaneously executed to two or more remote device stations (up to four stations).
Note, however, that only one dedicated instruction can be executed to a single remote device station. If a dedicated
instruction is executed before the processing of another instruction has not been completed, the instruction executed later
will complete with an error. Create the program so that the next dedicated instruction will start after the completion device
turns on, because processing of a dedicated instruction takes several scans until its completion.
• The G(P).RDMSG instruction uses a part or all of remote register that performs cyclic transmission between the master
station and the target station in the system. For programming, refer to the manual for the remote device station targeted.
Add SW0160 to SW0163 (Remote register use prohibited status) to a program as an interlock.
