Table E.D Digit 1 – Defines what logic must be met to jump to a step other than the
very next step.
Table E.E Digit 0 – Defines what logic must be met to jump to the very next step.
Setting Description Logic
0 Skip Step (jump immediately) SKIP
1 Step based on the time programmed in the respective [Stp Logic Time x]
parameter.
TIMED

6 Step if either “Logic In1” or “Logic In2” is active (logically true) OR
7 Step if both “Logic In1” and “Logic In2” is active (logically true) AND
8 Step if neither “Logic In1” or “Logic In2” is active (logically true) NOR
9 Step if “Logic In1” is active (logically true) and “Logic In2” is not active
(logically false)
XOR
A Step if “Logic In2” is active (logically true) and “Logic In1” is not active
(logically false)
