Title: Energizing an ouput
Post by: grahm610 on January 16, 2013, 12:00:41 PM

I am trying to energize an output on a D2-32TD2 using a D2-260 processor.. the rung is true but the output is not suppying energy to the circuit. The wireing is correct , checked it twice , please help.

What is the PLC mode?  (Run vs. Stop/Program)?

Its in run mode , I think its a I/O config problem , how can I check that??

If the I/O config mode is set to 'auto', there isn't much you can do either way. When it powers up, the CPU scans the I/O and configures appropriately.

I was wrong on the wiring , if you use a ZL-RT40 feedthrough connector A0 is terminal 21 and A5 is terminal 1 on the connector. After I changed the wiring all was good , what a rookie mistake!!!

Don't feel bad.  I've been doing this for decades and I recently did a similar thing on a job with ZipLinks.  I arranged the ZipLinks on a vertical DIN rail with the terminals facing to the right with the first on top, then the second and so on.  With the overall flow being from top to bottom, I didn't stop to think till after I wired the first one, that the flow was still left to right within a particular ZipLink, which would be bottom to top in my layout!   :D
