Remote operation of a PLC HMI Client

A PLC HMI Client can also be operated remotely on a third computer, which is neither the development computer nor the control computer. To do this, the following requirements must be met:

• A TwinCAT 3 Build 4018.0 ADS or later is installed on the system.
• ADS communication is established with the control computer on which the visualization code is executed (TwinCAT Icon > Router > Edit Routes > Add…).
• The Tc3PlcHmi folder has been copied from the development or control computer to the third system. The path for the folder must be added manually.
• The Tc3PlcHmi.ini file was adjusted on the system, on which the client is to run.
