  1. This working, it connecting to sensor. Also the sensor wire A and B hook up to probe was backwards. But the unistream manual says D+ = B and D- = A. Switched this and it connected.
  2. It just a blank program . Just trying to a reading through being online, looking at global tags. Thanks for the help. test1.ulpr
  3. Tried that as well. Tried this as well. Do I need to create some ladder logic to make connect and read?
  4. Still not having luck. My usb rs485 finds the device. But unistream is still not making the connection. Kinda lost at this point.
  5. Thanks. For the advice.
  6. Yeah still not having any luck with this. I am thinking I am trouble understanding the address location of my device.
  7. I haven't really done anything really. This is about as far as I got.
  8. New to using RS485 modbus. I am wanting to set up a new pH sensor using modbus. Not sure where to begin with this. I know i set-up unistream hmi as master. I want to read pH and then calibrate the sensor. I have attached the paper work from sensor. Can't make heads or tails out of it. A simple program would make difference to understand what going on with the addresses and such. Thanks for the help!
  9. I tried running as admin. Nothing. I did get it working. I had them on a separate partition. I guess unistream doesn't like. So I put them all on c drive. Works fine now. I have all older version.
  10. I recently got a new laptop with Windows 11. So I installed Unistream 1.28.26 worked fine. Did installed every version up to latest. All opening fine on install. Keeping the older version as well. Before anything said. I have applications out there that are built on older version. Due to how long it takes to do downloads and updates on slow 4g internet can be. I have to keep using older version. Older version don't open. The splash screen starts then says loading components, Then just disappears. Running old version on old laptop worked fine.
  11. Was wondering if there is remote i/o outputs with 4 to 20 mA output. The URA-0004W and URA-0008W only shows 0 to 20 mA. Thanks Rog
  12. So we have several of the unistream units out there. But recently the last 2 we built with the exact program on them. Are having issues with analog inputs. They started to jump all over the place. Tried different signal wires same reading. Multi meter run series and analog signal not jumping all over the place, just smooth reading. I don't know if it the modules or the last firmware update. Was wondering if you guys had any thoughts. Thanks Rog
  13. We been having issues this modules. Work for sometime. Then all sudden the module fails. Reading from the input starts to jump all over the place. It turns out one the inputs causes it. Removed the input. We have this set up to read from the source. Is there something causing this fail. We have replaced bunch of the AI8. Never have issues with AI4 modules. Thanks
  14. It would good to see in this set-up. You set your triggers and then it linked to a bit. That is could be used to a Digital output for physical alarm. When they acknowledge it. Then reset timers for alarm. To go off again till it resolved. Just suggestion. Save whole a lot of time in ladder logic.
