Command execution procedure

Command Processing Flow

There are two methods for executing a command: "PLC Terminal" and "Polling". If "Polling" is selected, terminal control is
not required but the communication for polling is required, and the command execution may be slower than "PLC Terminal".

"PLC Terminal"

Executes a command when the input terminal IN15 "PLC Terminal" is set.

"Polling"

Always monitors (polls) the data memory specified in "Command Execute Address (bit)", and executes a command
when it is set.
