Hello,

If you are using RMS, please check this video, for instructions on how to create VPN HUB, to establish connectivity to a PLC behind Teltonika device remotely.

Best regards,

Answer 1

How do you want to access the PLC? Via Ethernet, RS485, RS232?

If Ethernet, you can:
1) Forward a port to the PLC

2) Setup a VPN so that you can connect your computer to the modem network and then communicate direct to the PLC
