E1000 and Q Series Comm plus OPC

[cadomanis]

I am wondering if anyone has experience solving slow communication problems between E1000 panels and Q series PLCs. THe added wrinkle to my problems involves also conenctijg tothe same PLC viz OPC using KepWare. What I am finding is that I can get a very fast and reliable conentio nestalished between OPC and PLC. However as soon as I conencted the E1000, my communications get incredibly slow. The update rate of te E1000 is also very slow. I have the OPC conencted via multiple configured TCP ports. I have tried conencting the E1000 on a TCP port, UDP port, and even serial into front port. In all cases, its update is very slow and it immediately slows the OPC comunications by 8-10 times. Any idas, comments, or solutions anyone might have would be a big help. I have 2 installations suffering with this issue, whith a thrid in developemtn right now.

Maybe there are too many data loggings /readings done by the terminal. When you connect E1000, does the send/receive leds in front of the QJ71E71 blink like mad? I suggest trying with an empty E1000 project.

The screen update times for the 'E' range are quite slow but there are at least 2 ways to speed these up. 1. Make sure you have the latest version of the driver for the panel ("Check for updates" is available from the menu bar). 2. Ensure that the tags are as close together as possible for each page. EG. Displaying 10 digital objects on page 1 using M100, M101, M102, M103 ..... M109 is faster than using M100, M236, M1002, M7234, M0, M543 etc The same is true for Data registers, Counters, Timers etc. Hope this helps, Best Regrds Paul Ked

You may have tried this already, but I had a similiar problem using an E910 talking to 2 different servo drives (slow comms!) I changed the timeout setting in the peripherals/controller settings (advanced tab) from the default of 2000ms to 200ms and it helped. Bob Talbot
