Siemens Enhanced driver extremely slow

[Robbe_Meyvis]

I’m using the Siemens Enhanced driver with Ignition Edge 8.3.4, but it’s extremely slow.
It can take up to 10 seconds to see a tag changing.

Below my setup:

To try to get it a bit more useable, I troed changing the tag group:
Changed the default group to this:

I also need to read about 40 strings from the PLC.
I’ve put them in a 10 000 ms tag group:

If I disable those 40 tags, I can see other tags changing in about 3 seconds.
Which is still way to long to have a useable HMI.

The PLC I’m reading from is a Siemens 1212C (6ES7 212-1AE40-0XB0) with FW4.5.

No crazy network: just a windows 11 PC with the gateway installed –> to a gbit switch –> PLC.

Does anyone have suggestions on how to get everything useable?
Am I using too many tags?

I’ve not used this Siemens Module before but have you double checked all the Tag Configs are using the right Tag Groups, etc? Of course your string values will only change every 10s (as the Tag Group is defined as 10s).

Try changing your Default Tag Group’s Mode from using “Leased” to “Direct” and see how if that makes any changes. Over TCP you should be able to read at the very least every second over direct so give that a go but no you don’t have too many tags (Ignition can handle thousands to millions of tags).
