Hi,

TIA version 17

CPU 1513-1 project was working fine with a Comfort panel & project was changed to include an IPC277e nano.

Changed device, all connections look good but no connecting to PLC.

If I wire the Topology for port cableing I get an incorrect partner installed.

It is a IPC277e single touch landscape - only one version in the catalogue.

All firmware's are upto date.

any ideas?

Set as S7Online as per project.

attempted the TCPIP ports incase that's what was required

Cracked it!!!

Whilst changing PC/PG interface I noticed that TCPIP.Auto 2 was Active.

I am plugged into X1, I took it X1 was TCPIP.Auto1?

Selected Auto2 & jumped into life - Not really clear to be fair as Port 2 has not been configured.
