Siemens Enhanced Driver stuck in ReconnectWait

Ignition
1

Hello everyone,

I’m facing an issue with Ignition 8.3.0 while connecting to a Siemens PLC using the Siemens Enhanced Driver.

Problem description:

  • When I configure the PLC using the Siemens Enhanced Driver, the device status always remains ReconnectWait

  • No tags come online

  • No clear error messages are shown in the gateway logs (only reconnect attempts)

What works:

  • Using the Standard Siemens S7 driver, the same PLC, same IP, and same network, the connection works without any issue

  • Communication is stable and tags read correctly

Environment:

  • Ignition version: 8.3.0

  • PLC: Siemens S7 (tested on the same hardware)

  • Network: No firewall changes, same subnet

  • Port 102 is reachable and confirmed open

A known limitation or bug in Ignition 8.3?

  • Related to specific PLC firmware versions?

  • Caused by connection limits or TSAP / optimized block access settings?

Any guidance or confirmation would be appreciated.

Thanks in advance.

There should be a reason for being unable to connect in your logs. You might have to turn on debug level logs for the Siemens loggers, though. I'll edit this post in a moment with the names of the relevant loggers.

FYI, If you use "Absolute" address type, that will connect more similarly to the older S7-1200 driver. "Symbolic" uses a different connection type. You probably want to use symbolic.

If you don't want to share them via the forum, you can upload them to my dropbox, but sharing on the forum helps others who stumble in the future:

EDIT: Setting these two loggers two debug should get everything related to the driver. You should see a little arrow to expand relevant log messages.
