Vidmas30 Posted May 16, 2012 Report Share Posted May 16, 2012 Hello, Is it necessary for PLC's to be in the same LAN for ModBus TCP/IP communication? we need to get communication between two PLC's (v350 and v570 with ethernet cards) which are connected to different public IP addresses. So if we do some port forwarding to internal IP's would this work? Thank you! Quote Link to comment Share on other sites More sharing options...
