Fieldbus Inputs/Outputs
Functions set in the Softstarter as Fieldbus digital inputs
(DI) are in fact the digital inputs to the PLC i.e. the data
flow from the Softstarter through the network to the PLC.
Fieldbus digital outputs (DO) are not configurable. The
output (DO) gives a description of data flow from the
network to the Softstarter i.e. appears as an input, from
the Softstarter point of view.
Fieldbus communication has these parameters:
Parameter Description Setting range Default value
12.01 Com3 function Sets the function of the Com3
port.
None, Test, Modbus RTU slave,
Extension IO
Test
12.02 FB interface connector Sets the Fieldbus interface
selection.
FbPlug, Modbus RTU, Anybus,
None
None
12.03 Fieldbus control Enables control from fieldbus. Off, On Off
12.04 Fieldbus address Sets the Bus address. 0 ... 65535 0
