Value showing on Control always Zero


I am trying to integrate Modbus slave using simulator and configured following details

Bridge modbus:tcp:SH2WEB [ host=“”, port=502, id=1 ] {
// smart-house (Fx) Sovrum 4 (Kontor) - Ljusfunktion Tak_Status
Bridge poller P1 [ start=4000, length=1, refresh=1000, type=“holding” ] {
Thing data D1 [ readStart=“4000”, readValueType=“uint16”, writeStart=“0”, writeValueType=“uint16”, writeType=“holding” ]



Number ModbusDataNumber “Value as number [%.2f ]” {channel=“modbus:data:SH2WEB:P1:D1:number”}


Modbus client sending data on holding regeisters

But always I am seeing the data displayed on Modbus data as 0

I am failing to understand the reson although last read time is getting updated as expected
