AC and DC power
1.
Power the C Controller module ON.
2.
Run the C Controller module.
3.
RA2 turns ON when DC power is established.
4.
XM turns ON when RA2 turns ON, and the processing is started with a user program after DC input signal has fully been
established.
5.
Turn the start switch ON.
6.
The output devices are activated by using a user program when the relay (MC) turns ON.
User program
Create a program to perform the following operations when C Controller module starts.
■
Turning Ym ON when the battery voltage drop is detected
Use the C Controller module dedicated functions (CCPU_GetErrInfo, CCPU_Y_Out_BitEx).
■
Turning Yn ON when the user program is started
Use the C Controller module dedicated functions (CCPU_GetErrInfo, CCPU_Y_Out_BitEx).
■
Starting the system processing once XM turns ON and the DC input signal has settled (after
DC input signal settling time)
Create a program to start the system processing once the DC input signal setting time has passed after XM turns ON, which
can be checked with the CCPU_X_In_BitEx function. (The DC input signal setting time is a time from when RA2 turns ON to
when the DC input signal settles 100%. Set the time to 0.5 seconds.)
However, setting the DC input signal settling time in the user program is not required when a voltage relay is used for RA2.)
