The serial link port is used to communicate with devices via RS-232 or RS-485.
NOTE: Vijeo Designer has many serial protocols supported as well that can be used independently of SoMachine if the COM1 port is not required for use within SoMachine.
This isolated serial port allows HMISCU controller component to communicate with 2 protocols:
SoMachine for link with SoMachine compliant device (routing or variable access)
Modbus in order to meet the needs of master/slave architectures with Schneider Electric or third-party devices
NOTE: Under most circumstances, you should avoid connecting multiple instances of SoMachine to the same controller via the serial line, Ethernet and/or the USB port simultaneously. It is possible that conflicts could arise in actions taken by the various instances of SoMachine such as program, configuration or data edits, or control commands to the controller or its application. For more information, see the programming guide for your particular controller.
NOTE: If the user chooses to use Vijeo Designer serial protocols, they must delete any nodes (Modbus/SoMachineNetwork) under the COM1 node in their SoMachine Editor project.
The figure shows the location of the RJ45 serial port on the rear module:
Do not confuse the RJ45 serial port with the RJ45 Ethernet connector.
