Semigraphic Ladder Symbols
Ladder logic which is in Semigraphic form and symbol library
By Shreeshail Joshi on 1 March, 2018 - 6:45 am

I have a Ladder logic which is in Semigraphic form, I do not understand its symbols {eg "]<[", "]=[", "+--[PULS]-----]=[------[K2]-------------------------------------------------------------------( )--"}

Please guide me if anyone knows these symbols. Aso i would like a symbol library for reference.

Defiantly uncommon to what I have seen, looks like a combination of ladder with logic gate terminology.

What brand of PLC is it? referring to the OEM manual might be the best source of information.


the specifics will be covered in the programming manual,
