The system I am working has gateway and client and database all on one machine with two NICs. One NIC is for the single PLC being accessed and the other is configured by the custimer IT guy to link to his network and allow internet access.
When I disable the comnay NIC (to run some tests on unrelated equipement) Ignition loses connection to the PLC which is on the NIC still in use. I can still monitor the PLC on the active NIC, but I don’t understand why the 2nd LAN is affecting Ignition. I did not find a way to specify which network connection to use in the device settings in Ignition.
There may be a conflict with the way their IT manager has his port set up. It is a totally different IP address. This conflict may be the reason I have to disable the other NIC in order to get this other utility to work properly.
But is there any method I can use to force Ignition to use a particular LAN interface for device connections?
