  1. Thank you, I will try this today but the problem is the event is random and happens every week, I dont have any way to force/simulate this issue so i wont know if it solved my problem for a week or so.
  2. Hi Thanks for your reply, If i swap the modules and the wiring terminals, do i have to make any changes to the hardware configuration in unilogic?
  3. Hi I have a Unistream with the following modules and positions UID-1600 @ 0 Di module UID-0016R @ 1 DO relay module UID-0402N @ 2 AI/AO module UID-0402N @ 3 AI/AO module I dont have any analog outputs on the UID-0402N modules, on one of the 0402N the 4-20ma signal coming in on channel 4 from a level transmitter randomly reads 0% for 2 mins and then comes back to actual level after that for 2 more minutes and then goes back to 0 for 2 mins and so on. while this is happening the display on the transmitter reads correct the whole time and the 4-20ma on the terminal blocks read fine(checked with meter). If i power cycle the UNIStream the problem gets fixed for a few days and then it starts up again. any help on this would be greatly appretiated.
  4. Thank you so much for the responses and sorry for my late reply, for some reason I got no notification of replies to my thread. Joe, I have attached my entire program. Ausman, From what I understand that the sequences may be incorrect but they are the exact same logic with the exact same sequence for total and weekly, why are the readings different for both of them? Thank you guys once again for taking the time. Regards, Vijay
  5. HI everyone. I have a Unitronics PLC with HMI USP-104-B10 I have a Flow meter connected to one of the Analog input cards and it sends out a flow rate, I want to calculate the total flow in cubic meters and display it on the HMI, I also want another display with Weekly Flow ( so it uses the same logic and calculations of the total flow but should reset every time the operator pushes a reset button after he takes his readings). Both The Calculations are the Exact same logic the difference is they are assigned to different tags. But the readings are completely different and random.
