Considerations when detecting devices supporting iQSS
■Station numbers of slave stations are not sequential
When an automatic detection of connected devices is performed in a system configuration in which the station numbers of
slave stations are not sequential, a general-purpose remote I/O station is automatically set for a station without a station
number as a reserved station.
Arrange the stations and change the modules in accordance with the actual module configuration.
■"General Module" is displayed
After performing an automatic detection of connected devices, a reserved station and a station which is not included in the
module parameter are displayed as "General Module".
In that case, turn the power OFF, and ON again in the order from the slave station to the master station. Then, perform an
automatic detection of connected devices again.
■A system configuration is changed
When a system configuration is changed (stations are added or changed), a slave station may not be detected.
In that case, turn the power OFF, and ON again in the order from the slave station to the master station. Then, perform an
automatic detection of connected devices again.
■A standby master station is included in a system configuration
When a standby master station is included in a system configuration, the last station number is set for the station.
Change the station number in accordance with the actual system configuration.
■The operation is switched from the standby master operation to the master operation
When the standby master operation is switched to the master operation, a station whose operation is switched to the master
operation will not be detected.

In that case, turn the power OFF, and ON again in the order from the standby master station to the master station. Then,
perform an automatic detection of connected devices again.
■Use of the function via Ethernet
To perform an automatic detection of connected devices, connect a built-in Ethernet port CPU with an Ethernet cable.
An automatic detection of connected device cannot be performed when connecting to an RJ71EN71 or RnENCPU (network
part).
