  1. Micro850-I/O tags reading zero/not updating

    What position is the mode switch on the PLC in?  Are the sensors 2 wire or 4 wire and how do you have them wired.
  2. Rslinx and Studio 5000 Whois

    First guess, try deleting your harmony files.  They can cause unusual browsing issues such as this.  Also, are you using the Ethernet/IP driver or the Ethernet devices driver?  See if one or the other makes a difference.  https://twcontrols.com/lessons/troubleshooting-rslinx-browsing-programs-caused-by-harmony-files

  4. You need to post your code so we can look at it.
  5. How long are you wanting to energize for? For that single full minute? If so, why are you using the OTL? The OTE would make it true for that minute only.
  6. Run Powerflex 525 from keypad?

    Glad I could help.
  7. Run Powerflex 525 from keypad?

    Study on parameter P046, that is your command source, and P047, that is your speed reference.
  8. Run Powerflex 525 from keypad?

    Are they brand new out of the box?  If so turn the potentiometer to the right and hit the green button the the keypad.  
  9. micrologix 1200 watchdog

    Did the system used to work without faulting? It usually means there is a grounding problem but if a system has been working for years and suddenly gets this then it could be a PLC going bad.
  10. Flow Meter on Micrologix 1400

    A basic converter probably won't work.  They usually will have capacitors to help them smooth out the ripples that the high speed counter senses.  You need something like a optocoupler.  Maybe something like this. https://www.phoenixcontact.com/online/portal/us?urile=pxc-oc-itemdetail:pid=2964270&library=usen&tab=1
  11. Flow Meter on Micrologix 1400

    Probably cheapest to get a 24V hall effect sensor.  Transformers don't work with DC applications though there are isolators that may work. It will depend on the sensor as to whether you need or what value the pull up resistor needs to be.
  12. Flow Meter on Micrologix 1400

    The Micrologix 1400 inputs are 24VDC, 6 volt won't work. What is the maximum voltage of your sensor?

    Glad you found it helpful.

    Does this help? https://www.theautomationstore.com/rslogix-500-training-where-can-i-download-rslogix-500-and-what-is-the-price-difference-of-each-version/
  15. Allen Bradley 1747-UIC DH485 Issues

    He's pretty sharp so if he said only pin 3 is missing then he is probably right. If you are sure the DF1 driver settings match what I showed in the lesson then I can only think of three things. The UIC is bad (not likely), the C13 pinout is incorrect ( ohm it out) or the SLC port is faulty.
