7 APPLICATION FUNCTIONS
7.8 I/O Assignment Function
Master Remote
The I/O assignment function is used for the following:
1) Reserving points when changing to a module other than 16-point modules
2) Preventing I/O number change after module replacement
3) Changing I/O numbers to those used in the program
4) Setting input response time (I/O response time)
5) Setting an output mode for a data link error (Error time output mode setting)
6) Setting a remote I/O station operation mode for a hardware error in an intelligent

5) Setting an output mode for a data link error (Error time output mode setting)
6) Setting a remote I/O station operation mode for a hardware error in an intelligent
function module (Hardware error time CPU operation mode setting)
7) Setting intelligent function module switches
To enable the I/O assignment functions, use GX Developer to set the I/O assignment
settings in the PLC parameters for the remote I/O station. The I/O assignments are
set within common parameter setting range that has been set in remote master station.
As for the I/O assignment settings in the PLC parameters of the remote master station,
the I/O assignment within the remote master station are enabled but they are not
enabled in the remote I/O station.
Moreover, the I/O assignment of the remote I/O station is only set for remote I/O
stations requiring I/O assignment. There is no need to set for all remote I/O stations.
