Dimmer with modbus binding

Hey guys,

I’m looking for a way to use modbus to control some dimmerValues in a wago plc.

Dimmer BarLEDG “Bar LED Green” (gWohn) {modbus=“slave2:1”}

modbus:tcp.slave2.connection=10.0.0.146:502
modbus:tcp.slave2.id=1
modbus:tcp.slave2.start=12289
modbus:tcp.slave2.length=4
modbus:tcp.slave2.type=holding
modbus:tcp.slave2.valuetype=uint16

Actually the modbus binding only supports switches and numbers.
Any idea how I can use it to control a dimmerItem?
Maybe there is someone who modified the modbus-binding to work with dimmer?
