(1) Setting the baud rate for DeviceNet communication
The baud rate must be the same between the Gateway Unit and the PLC master.
[1] Gateway
Unit
Baud-rate setting switches (DR0, DR1) (Refer to 2.3.)
[2] PLC master
Baud-rate setting switches of the master unit (Refer to the operation manual for the
PLC.)
(2) Node address
[1] Gateway Unit
Node-address setting switches (NA1 to NA32) (Refer to 2.3.)
[2] PLC master
Node-address setting switches (Refer to the operation manual for the
PLC.)
* Normally the node address of the PLC master is set to 63.
(3) Setting the Gateway Unit mode
Set the operation mode of the Gateway Unit using the mode setting switch SW1 (refer to 2.3).
The settings of this switch determine the I/O size of the Gateway Unit. Accordingly, register this
information in the master as a slave-station I/O assignment setting. (Refer to 8.4.3.)
