ProCOM Mapping

If your system uses remote PCs that only support COM port behavior to control remote Modbus devices, then ProCOM is the best solution for your system. Before using ProCOM, your PC needs to create virtual

COM ports that connect to a specific ProCOM over an Ethernet network. By using ProCOM, the MGate

MB3x70 will treat your PC’s COM port as if it were an additional serial port on the MGate MB3x70.

Configuring ProCOM

To enable this function, ProCOM mapping must be completed as follows:

Locate the MGate MB3x70 with the search function, select the MGate MB3x70 device that you want to set

ProCOM for, and then click ProCOM Mapping to enter the mapping dialog box, as illustrated by the following figures.

On the ProCOM mapping dialog box, you can map up to four ProCOM functions for each Modbus gateway to your PC’s COM ports. The driver will generate virtual COM ports on your PC to connect to the selected

MGate MB3x70 over the network.

This way, when you send a Modbus request to ProCOM, the driver will forward your request to the MGate

MB3x70 and the MGate MB3x70 will forward the request to the target Modbus device using the preset

Modbus device mode and Slave ID. For example, the Modbus request from ProCOM can be redirected to a

Modbus RTU/ASCII device that is behind the MGate MB3x70’s serial interface or to a Modbus TCP device through the MGate MB3x70’s Ethernet port. In addition, it can be redirected to another ProCOM port on the

MGate MB3x70.
