Micrologix 1100 Series A

i cannot get my micrologix series a to connect to ignition.

is it because the subnet has been changed since the gateway is installed?

i can currently ping the ml1100 from the host computer.

any ideas??

sorry this is under the wrong topic

I was able to swap the ML1100 for a series B processor 1763-L16BBB Firmware 9 and it connected.

Has anyone else had a problem connecting to an older Micrologix series A firmware 3?
is this supported? or do i need to flash the firmware

You might try upgrading the firmware to series B, as the A only allows one ethernet connection.
