The communication setting and the ladder program creation are now finished, when MP2300 acts as a master.
( 3 ) How to Start Communications
1.
The MP2300S side starts to receive the messages.
As the sample ladder program automatically starts the message receive operation just after system startup, you
are not required to do anything. In normal operation, accept the default.
2.
Turn Execute ON for the message transmit function in the MP2300 side to transmit messages.
Messages are transmitted by turning on the register DB000200 configured in Execute of the message transmit

The sample ladder program is created to transmit a message every one second when five seconds have elapsed
after the low-speed scan (or high-speed scan) startup.
To change the message transmission interval, change the timer value c.
