Glad you got it working. Thanks for letting us know.

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/

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.

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?

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/

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/

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.

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/

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?

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

Thank you!

Thanks!  

Thanks Mickey and Izzybe.  It means a lot!
