I am currently working on a project that connects 10 seperate controlers through Modbus IP. This is in a large office building and so the network administrator has provided me with static IP addresses for all the panels that vary depending on what part of the building they are in and what switch they are connected to (ie. 163.194.232.61, 163.194.239.15 etc..). I am able to connect with every panel through Remote Access but my master panel is unable to connect through Modbus IP. I am not a networking guy so I am probably missing something simple. In Modbus IP what is the proper way to set up communications. Does the default gateway value need to match on all the panels or is there something else I am missing?
