GE Boolean for Series One Jr,

[ace 0]

Hi, I have a JR. on a press at the plant I work. The rung that is in question reads: STR 2 and 162 or 5 and 161 str 160 or str out 162. Next rung is the same but with different adderess. The problem is the OR STR, how would this rung read in ladder logic? I can understand everything on the rung but the OR STR. Any Help would be great. Thanks ACE

The OR STR instruction combines the three parallel branches. It may be helpful to think of it as a "Close Parenthesis". The Series One Junior manual is posted here on MrPLC.com http://forums.mrplc.com/index.php?autocom=downloads&showfile=370 The discussion of the OR STR and AND STR instructions starts on page 5-13.
