Hello,

We are trying to set up communications from VT to a PLC5 over ethernet through a NET-ENI adapter. I can connect to the PLC over ethernet through RSLogix, but am only receiving errors on the VT end. I have the following configurations:

TCP/IP Port - IP address, port 44818
AB DF1 Driver - I have tried this both serial and TCP/IP but cannot read any values. I can see the driver will connect with 0 errors, but as soon as I add any tags it will error.

Any suggestions on settings to try for this? I can connect VT serial DF1 but once the ENI is installed I cannot.

you shouldnt be using the serial port tab, you should only use the TCP/IP tab of the DF1 driver. confirm the port is 44818 or port 2222.

If I remember correctly, you should try this:

1. create a separate TCP/IP port tag pointing to the NET-ENI on port 44818
2. set the AB driver to PLC/5 and Serial/Modem communications mode on the Type tab
3. set the Port to be the stand-alone TCP/IP port (from 1. above) on the Serial Tab
