  1. PLC Architectutre

    EN2TR is for controlLogix
  2. This video shows a simple way of backing up PF525 523 with no software installation
  3. PID Loop Help

    Thanks for the reply, Not sure if it works yet as only bench tested, i have thermocouples connected and measured the analogue output which is going in the right direction. will just have to see what happens when we test it for real.
  4. PID Loop Help

    Hello everyone, I am need some help with a project,  we are using liquid nitrogen to cool a product which runs on a conveyor through a tunnel which has liquid nitrogen controlled by a proportional valve using a thermocouple and a PID loop in the PLC currently i have a PIDE loop set in the PLC the temperatures have been scaled  (-150 to + 50 PV and set points from -20 to -100) to a range 0f 0 (-150) to 200 (+50) output from the PIDE is inverted for analogue output 0 - 10V What i want to know is - is this right in terms of scaling or should i be looking to do this another way  dont have much experience with PID in PLCs so any advice would be greatly appreciated   Regards Matt
  5. When to use HSC

    perfect thanks for the advice
  6. When to use HSC

    Good morning all, i need some advice about when to use a HSC, processor is L33 and i have two pulse inputs one at max 53Hz and the other at max 117Hz will this require a HSC?   Thanks in advance
  7. SLC 5/03 CPU is not running properly

    maybe start a new thread Rharo
  8. controllogix and 500 on IPAD

    They have an app call factory talk teamOne have look on the Rockwell automation site not sure the details but looks like you can access tag values
  9. How to update FactoryTalk View Studio?

    You should be able to update, enter the serial number and product key for the software you have and it will show you if you are entitled to download version 10, i did this recently from version 7 to 10 with no additional purchases   just to add any existing project will be converted to version 10 when you open them
  10. 1734-IB8S Input LED turns red.... Causes

    maybe there is some issue using a reed switch for this application. is it PNP/NPN type proximity switch mounted on the side of the Piston? I know this does not help you but using this type of switch with a Safety unit would not be classed as a safety switch. 
  11. what output does the flowmeter have? probably pulses? you would count the pulses either using a high speed counter or normal counter depending on the speed of the pulses.
  12. Panelview transfer of .mer file on USB

    maybe the FW was downgraded to match the MER file.
  13. Panelview transfer of .mer file on USB

    are you loading the .MER from the USB drive? you will need to copy to internal storage
  14. Retentive OTE

    yeah agreed & make sure the program will still be safe if you are going to OTL
  15. Retentive OTE

    OTL is retentive so you could write some code using OTL to keep the state of OTE during power cycle
