HMI to PLC Pass Through Connection

HMI to PLC Pass Through Connection

Pass-through function is a ability to modify, monitor, upload, and download PLC programs by connecting an HMI and PC with Ethernet or USB loader cable while the HMI and PLC are connected via RS232C communication.

By using the pass-through function, it is possible to reduce the hassle of changing cables or having to go directly in front of the PLC to modify the PLC program. Please refer to the attached document for more information.
