(2) External signal assignment function
This function allows remote input or output signals of the main A/D converter module to be assigned to remote
I/O signals of the extension I/O module connected. Signals can be input from the extension I/O module and error
signals can be output to the external at the fixed timing without influence from the sequence scan or link scan.
Target remote I/O signal of external signal assignment
Trigger conversion request (RY19)
Input signal error detection signal (RX1C)
Alert output signal (RX18)
Error flag (RXA)
Warning flag (RX7)
(a) How the external signal assignment function operates
Ex.
1: Assigning Trigger conversion request (RY19) of a main A/D converter module to RX2E of an extension
input module

flag (RX19)
Assigning a remote output signal of the main A/D converter module to a remote input signal of the extension input module
does not allow the pre-assigned remote output signal to be turned on/off or monitored by program. Change or monitor the
assigned remote input signal of the extension input module. (In the above example, change or monitor RX2E.)
