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.
