AB SLC500 Program Fault?

[tech1200]

Hi all,

I am new to PLC programming and decided to build a test rig (photo enclosed) to try and teach myself how to do it.

I have written a program which appears to run successfully although when I added in a section to flash pilot lights when the system is about to start, the pilot light outputs do not energize.

Any ideas? The suspect line in the program is 0010. It puzzles me because B3:05 in the line does become true.

I will enclose the program file, a photo of the rig and a note of my inputs and outputs.

Thanks in advance

Euan

Can I suggest that you attach the program file as simple text file or something similar, if possible.

There may be people here who can help but do not have the AB programming software instantly available.
