I'm struggling to find any descriptions of the different functions provided by these various relays in the mitsubishi documentation (surprise surprise)
Can anyone offer me some definitions, are these typically the same across the PLC board?
Where might I use a step relay instead of an annunciator relay etc..
Are there such things as annunciators and step relays in AB, Siemens, GE,
etc..?
Whats a link register when compared to a data register? or even link special?
Kind Regards,
UKB.
