3.
Click in the
Type
field to choose the required PLC type on Register 1, for example.
4.
Set up all the input/output registers in a similar way.
5.
Right click on a row to insert, move or delete a register.
6.
The Baudrate can be selected to be 125k, 250k or 500k.
7.
The MAC Id can be selected in the range 0 – 125.
NOTE
The Baudrate and MAC Id set in DSE will only be used if all the switches on the
DeviceNet Option are set to ON.
If the software set MAC Id is set to zero and the switches on the DeviceNet Option are all
set to ON, the option is disabled and will not appear on the DeviceNet network.

Conversion of DSE Type < > DeviceNet Type
The DSE fieldbus connectors are each assigned a DeviceNet PLC "Type" as described in "Step
1.3: Configuring the Fieldbus Connectors" on page 12. The conversion between the DSE type
and the PLC type is performed automatically (refer to Appendix B : DSE/DeviceNet Conversion
Rules, page 26).
Any PLC type can be assigned to a fieldbus connector
