Send que full, data request t........

[BigDollaBill1234]

I have a SCADA network running on AdvancedHMI, works great, awesome software I love it. I only have one nagging problem..

I have multiple different machines reporting to AHMI. My controllogix's sets work great NO issues...

My drivers for SLC500 Ethernet work OK, except after I start and run my AHMI for awhile say hour or so, only on my parts counter I get ... Send que full, data request t...... scrolling across my PARTS label inside my counter. my other digital displays for downtime and previous shift counts, don't do this... Only the PARTS counter ( current production ) . I have 2 different PLCs , both are SLC500 Ethernet...both do the same exact thing...

I read other posts that said try increasing poll rate...I got to 8000....still same thing, no change at all

Also changed disable subscription to true , again no change


Please anyone, any tips? Thanks

The SendQue Full usually means there is a loss of communications even if it just drops out for a minute. Are you doing any reading/writing in code? What version are you using?

3.97e , have multiple units reporting to ADVHMI. My controllogix Ethernet units are fine, no problems, my SLC500 Ethernet units both give me the send que full problem after about 5 or 10 minutes, stop debugging and restart, no problems till 5 or 10 mins. Both controllogix and SLC500 drivers match all settings but the SLC500 gives me problems.

Are you doing any reads in code? If so, are you using Read or BeginRead?

If not, try increasing the value in PollRateOverride.
