Modicon Momentum Unity CBU RTC

bluenoser337 · Sep 4, 2016

First time with Unity Pro and a new Unity CBU (Central Brocessing Unit??)

Trying to read the RTC but having no luck at all. Can't be that difficult so I must be missing something simple.

Thanks!

You need system words for this.

it is years, when I programmed momentum PLC and it was Concept programmed.

On concept time was on some %4X registers

Try: RRTC or RRTC_DT -blocks, it looks like that momentum don't use system words to this

also make sure the clock is actually set. I think data can be zeroes if clock is not set!
