When using the Modbus Scanner, the communication status is represented by a read-only object that reflects the current state of communication with a Modbus RTU Server or Modbus/TCP Server1. This status object is named in the format MBUS_DeviceName_CommStatus.

Here's what the different status codes for communication status mean:

0 - Device not found: The Modbus device could not be located.

1 - Trying to contact device: The system is attempting to establish contact with the Modbus device.

2 - Initializing device: The Modbus device is currently being initialized.

3 - Communications with device were unsuccessful: Communication attempts with the device have failed.

4 - Device is online: The Modbus device is successfully communicating and online.

5 - Device is disabled: The Modbus device has been disabled.

These status objects are part of the information provided by the Modbus RTU Client or Modbus/TCP Client operations when the Modbus Client options are enabled in the RemoteConnect project settings.
