(2) External signal assignment function
This function allows remote input or output signals of the main D/A 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 signals of external signal assignment
Trigger output request (RY19)
Alert output signal (RX1E)
Error flag (RXA)
Warning flag (RX7)

Assigning a remote input signal of the main D/A converter module to a remote output signal of the extension output module
does not allow the assigned remote output signal to be turned on/off or monitored by program. Turn on/off or monitor the pre-
assigned remote input signal of the main module. (In the above example, turn on/off or monitor RY2A.)
