Siemens Enhanced Driver Randomly Disconnected

Ignition
1

Hi everyone,

I am facing a severe stability issue connecting a Siemens S7-1510SP to Ignition 8.3.3 using the Siemens S7-1500 (Symbolic) driver.

The Issue: The device connects successfully and reads tags, but experiences random disconnects.

  • Unlike the issue described in this thread, my disconnects do not seem triggered by adding specific tags.

  • The behavior is time-based but irregular: sometimes it stays connected for 5 minutes, sometimes 10 minutes, then drops.

Crucially, it does not auto-reconnect.

  • The connection does not change to "Bad" but It won’t update the data.

  • The only way to get data back is to go into the Gateway and manually "Refresh & Browse". Immediately after I do this manual step, the data returns instantly.

Troubleshooting Done:

  1. Firmware: My PLC is already on the latest firmware (V4.0.4).

  2. TIA Portal Security:

    • "Only allow secure PG/PC/HMI communication" is UNCHECKED.

    • "Permit access with PUT/GET..." is CHECKED.

  3. Ignition Settings:

    • Host: 192.168.10.10

    • Rack: 0, Slot: 1

    • Optimize Write: True

Do we have any solutions for this?

Sounds like this: Siemens Redundant CPU forcing Refresh Browse to update values - #4 by Cody_Morgan

It has been fixed for the 8.3.4 release. An updated module is available in the 8.3.5 nightly release stream as well.
