Posted 26 May 2017 Hi Guys, I got assigned here on a job and Im trying to figure out to restore communication between an Omron PLC and kepware - kepserver. We have a moxa nport device to convert the serial to TCP/IP ,.. I am able to ping the device itself so the network communication up to there is alright. I must say that before I was asked to verify - a couple of months ago the communication was working fine. Something has happened in between these time which of course nobody knows, and I have to fix it to get it operational again,... I uploaded here some images from the kepware and moxa nport settings if any could assist in what is going wrong - please let me know. 1 more thing. at 1 device I was able to get updates by putting the Scan Mode on a forced setting and requesting each 500ms to pull data. Only thing is that I only get an update every 2minutes while it should be at least every second,. the data value is changing every minute. Share this post Link to post Share on other sites
