Modbus TCP Source

Modbus TCP Source

The Modbus TCP source is used to receive data from a device compatible with the Modbus protocol.
​

Modbus TCP does not have any built-in source variables. All variables are custom variables, which must be created under the DataXchange Tab → Variable → Modbus TCP. All of these variables are licensed at the Bronze level.

For bit values read via coil or discrete input values, select an Input Type of Digital. For any variable reading either a holding register or input register, select an Input Type of Analog.

To use these variables, the Modbus TCP Communication Source must be configured for an equipment.
