    I did quick fiddle with the data in Excel. It looks like an offset of -45 counts and then a linear scaling error of -2.4% over the range of the input. Fluke(ma) Actual Count Expected Count Count Diff. Data without offset Percentage Error 4.000 -45 0 -45 0 6.000 954 1024 -70 -25 -2.44% 8.000 1954 2048 -94 -49 -2.39% 12.000 3953 4096 -143 -98 -2.39% 14.000 4957 5119 -162 -117 -2.29% 16.000 5951 6143 -192 -147 -2.39% 18.000 6951 7167 -216 -171 -2.39% 20.000 7949 8191 -242 -197 -2.41% I would not expect this as normal behaviour. The spec sheet gives accuracy of 0.4%. However, apart from the offset and scaling errors, the data looks quite clean. Usually a bad input won't even perform this well. Were you able to test with the field wiring completely disconnected from the analogue module (that includes the commons as well as the signal lines)? I notice you are a few versions behind on UniLogic, the current version is 1.28.34. I doubt the issue is version related, but I would suggest upgrading at some point. I'd be pushing into a more thorough diagnosis of the hardware and field wiring first. Hope this helps,

    OK the operational state means that the PLC is unable to talk to the URB(it's not establishing a connection) 0- Establishing Connection (in Progress ) When you pinged the URB was that from a PC or the UniStream?? 1)Trying pinging the URB from the UniStream via Uniapps->Network->Ethernet->Ping 2)You've set IP address for both the panel and CPU(your PC will use the Panel IP to communicate with the PLC, the PLC will use the CPU IP to communicate with the URB) 3) Is it an isolated URB and PLC are on an isolated network or are you going over the top?? 4) how did you set the IP on the URB?
