5.1 Parameter Setting for Remote I/O Stations
CHAPTER 5 PARAMETER SETTING
To operate MELSECNET/10 remote I/O network, network parameters must be set to the CPU module on the remote
master station using a peripheral.
For the parameter setting for the MELSECNET/10 remote master module, refer to the following.
Reference manual for the MELSECNET/10 network system used
5.1 Parameter Setting for Remote I/O Stations
This section describes parameters set to the MELSECNET/H (MELSECNET/10 mode) remote I/O station.
To use the MELSEC-Q series functions on the MELSECNET/H (MELSECNET/10 mode) remote I/O station, set
parameters to the MELSECNET/H remote I/O module.
To use the MELSECNET/H (MELSECNET/10 mode) remote I/O station as a remote I/O station equivalent to that for
the MELSEC-A/QnA series, set only intelligent function module switch parameters.
The set parameters are enabled when one of the following is performed.
• Reset the MELSECNET/H remote I/O module.
• Power off and on the MELSECNET/H remote I/O module.
• When the parameters of the remote I/O station are corrected and the remote I/O station has not been reset: Reset
the CPU module on the remote master station, switch the status of the CPU module from STOP to RUN, or power
off and on the programmable controller.
• When a stop error exists on the remote I/O station: Reset the CPU module on the remote master station, switch
the status of the CPU module from STOP to RUN, or power off and on the programmable controller.
(1) PLC parameter
The PLC parameter can be set to the MELSECNET/H remote I/O module as well as being set to the CPU
module. The following table lists the setting availability on the MELSECNET/H (MELSECNET/10 mode) remote
I/O station.
For details on the "PLC system", "PLC RAS", and "I/O assignment" parameter settings, refer to the following.
