Precautions during programming
This instruction is valid only if the setting on the controller side has been set to
the computer link mode or the PLC link mode. It is invalid in the general
communication mode.
Executing this instruction does not change the settings in the system registers.
We recommend using differential execution with this instruction.

If a commercial RS232C/RS485 converter is being used in the PLC link mode,
this instruction should be programmed in all of the stations (PLCs) connected to
the link.
