Hi. I don't fully understand the setup of a modbusTCP bridge. So does anybody have a sample of a bridge configuration reading 10 HR from addr 100 from node 5 and 10.

input:
  modbus:
    controller: 'tcp://<your-device-ip>:502'
    slaveIDs:
      - 5
      - 10
    timeout: '1s'
    timeBetweenReads: '1s'
    addresses:
      - name: "yourRegisterName"
        register: "holding"
        address: 10
        type: "BIT"
        output: "BOOL"

Hey @fogh62 it should be something like this, i assumed by

node

you're speaking about the slaveIDs. Then for the addresses part you have to specify the address e.g. holding register 10 and in

register

you specify the type in this case

holding

All those configuration options can be seen here in the documentation https://docs.umh.app/benthos-umh/input/modbus

Hi Janik, thanks. I don't understand the BIT and BOOL stuff. But I will dig into the manual later. THANKS

no worries, feel free to ask if there is anything I can help you with. the

type: "BIT

is basically what you have inside the plc, so whether its a bit that was written or a UINT16 or whatever data structure is used. the

output : "BOOL"

is to what it converts, bool is basically 1 BIT which can have the value 1 or 0, which then is basically a bit
