Configuring Tag Reading on a Modbus Device Using SDG

When creating a connection to a Modbus device using the ModbusClient in the SDG, it is necessary to enable a specific option in the communication channel to allow tag reading.

This option is called MBActionMask0. Within this setting, the configuration must be adjusted to enable the SDG to read all available registers from the Modbus device.

Recommended steps:

Access the configuration of the communication channel associated with the ModbusClient.

Locate the MBActionMask0 option.


Enable or adjust the necessary parameters to allow full register reading.


Save the configuration and test the connection to ensure that the tags are being read correctly.
