  1. PLC Safe distance from 11KVA transformer

    While not the exact answer you are looking for, Rockwell Automation has an excellent document on System Design for Control of Electrical Noise https://literature.rockwellautomation.com/idc/groups/literature/documents/rm/gmc-rm001_-en-p.pdf
  2. how to use 32 bit register for mathematical operation

    What PLC are you using?
  3. Question on Micrologix 1400 series b

    Glad you got it chased down. Those problems can be hard to find. Thanks for letting us know.
  4. Question on Micrologix 1400 series b

    Wild guess here...Is the internal 24V power supply being used to power outputs?  My wild guess is you are overloading power supply which is dropping it out.  I would try removing all the wires but the power wire and see if it will stay on then.
  5. DB9 Connector SLC 5/03

    The limitation of RS-232 is 50 ft. Doesn't matter which protocol you run across it whether it be DF1 or DH485. You're still limited to 50 ft without repeaters
  6. Unconfigured I/O Address Used

    Glad you got it working. Thanks for letting us know.
  7. Unconfigured I/O Address Used

    Those are word level instructions so you are manipulating 16 points at a time. Have a look at the bit instructions. Here's a link to help you. https://www.theautomationstore.com/rslogix-500-training-xic-xio-ote-program-scan-step-by-step/
  8. Unconfigured I/O Address Used

    The I/O is addressed as I:S.W/B where S is the slot, W is the word, and B is the bit.  So you Inputs are I:0.0/0 - I:0.0/13 and your outputs are O:0.0/0- O:0.0/9.
  9. Unconfigured I/O Address Used

    The 1200 doesn't have I/O past I:0.1 on it's base unit.  Are you using expansion I/O?  Can you attached your program?
  10. Machine Step Sequence

    Here is a lesson series we did on different ways to sequence machines including counters, word/bit manipulation, multiplying integers, and sequencing instructions. https://www.theautomationstore.com/rslogix-500-training-programming-machine-sequences-to-do-an-automatic-process/
  11. A decent USB to RS232 adapter should work for connecting your cable to your laptop's USB port.  Here is one we sell. https://www.theautomationstore.com/industrial-usb-rs232-usb-serial-adapter-plc-programming/
  12. When to use HSC

    Yes that is exactly what the high speed counters are for.  While your application is low speed for a high speed counter, you risk missing pulses with regular inputs and ladder logic.
  13. Micrologix 1200 Fault

    Here are instructions on how to navigate to the fault code.  https://www.theautomationstore.com/rslogix-500-the-big-red-fault-finding-understanding-and-clearing/
  14. ML 1100

    It depends on the particular model of the PLC.  Some are 24VDC powered, some are 120VAC powered, and one is 12VDC powered.  What is the complete part number?
  15. Rockwell Automation You Make It Challenge

    He is in the top 3!  Now he must work on a presentation for Automation Fair and will be posting updates on his progress at  https://www.youtube.com/channel/UCqr9nnJswUG2-yAbHxQ8OAw
