7.8 I/O Assignment Function

Master Remote
The I/O assignment function is a convenient function for use under situations such as
the following: (1) when changing the I/O response time of the input module, (2) when
changing the error time output mode of the output module and (3) when setting the
setting switches for the intelligent function module.
In addition, this function can also be used for situations such as: (1) when you want to
set module data beforehand in order to conserve input/output numbers for the empty
slots on the remote I/O station, and (2) when you want to change the actual module
design and input/output number on the remote I/O station.
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.
