Hi folks, I am trying to read through a ladder logic diagram, can somebody tell me what KEEP, SBS and SNXT on the right side of the ladder logic rung stand for.

Seems Omron commands. If you have CX.Programmer or Sys-Win, use help or find from http://www.omron.com/

In OMRON CX-Programmer, under topic: Ladder Grammar:

SBS is Subroutine Call

SNXT is related to the STEP-SNXT instruction pair.

no mention of KEEP anywhere.

KEEP is Omron's name for latch/unlatch relays. They treat it as a single device with two inputs. (AKA SET/RESET by other vendors)
