Setting method
In the network configuration setting of the master station, set the total number of I/O points of the modules connected to the
remote head module, in 16-point units.
• To set an empty slot on the intelligent device station or to change a start I/O number, change the I/O
assignment setting in the remote head module.
• If the number of points will be increased for a system expansion in future, for example, set a large number
for the RX/RY setting in the network configuration setting of the master station. Doing so will eliminate the
need to change the parameter setting of the master station at the time of the system expansion. However,
increasing the number of points also increases the processing time.
