*1 Groups do not need to be numbered serially. For example, setting group No.2 only (number of groups: one) and setting group No.1 and
No.3 (number of groups: two) are both possible.
For the CPU module that does not support the group number setting function, however, group No. is fixed to 1. ( Page 58 Added

■Automatic detection of connected device
Actually connected slave stations are detected and reflected in the network configuration setting.
In the network configuration setting, communication settings such as IP addresses and subnet masks can be configured for
the detected slave stations.
Parameters that are inherent in the slave stations can also be read/written from/to the network configuration setting. (Some
slave stations do not support these features.)
Various settings of all slave stations can be configured in parameters of the master station (the settings do not need to be
configured in each individual slave station) and therefore the man-hour for the setting will be reduced.
Follow the operating procedure below to use the automatic detection of connected device.
1.
Start up a new project in GX Works3/GX Works2 and execute the automatic detection of connected device.
2.
Detected slave stations are reflected in the network configuration setting. Change the items such as the connection order
and numbers of occupied stations and set station numbers.
3.
Configure IP addresses and subnet masks of slave stations in the network configuration setting. And then, reflect the
settings to the slave stations.

Station]
4.
Parameters that are inherent in the slave stations can be read/written from/to the network configuration setting.
details on the parameters inherent in each slave station, refer to the manuals of the slave station used.

*1 To read parameters, select "Parameter read" from "Method selection" and click the [Execute] button. Parameters read are displayed in
the column of "Read Value". To write parameters, select "Parameter write" from "Method selection", input data to the column of "Write
Value", and then click the [Execute] button.
Slave station settings in the network configuration setting must be configured after executing the automatic
detection of connected device.
If not, contents of setting items that have been already configured in the network configuration setting are
overwritten by ones detected by the automatic detection. Detected slave stations are reflected in the network
configuration setting in ascending order of MAC address and values such as the number of occupied stations
becomes initial value.
