Digit 2 – Defines what logic must be met to jump to a step other than 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
2
Step if “Logic In 1” is active (logically true)
TRUE
3
Step if “Logic In 2” is active (logically true)
TRUE
4
Step if “Logic In 1” is not active (logically false)
FALSE
5
Step if “Logic In 2” is not active (logically false)
FALSE
6
Step if either “Logic In 1” or “Logic In 2” is active (logically true)
OR
7
Step if both “Logic In 1” and “Logic In 2” is active (logically true)
AND
8
Step if neither “Logic In 1” or “Logic In 2” is active (logically true)
NOR
9
Step if “Logic In 1” is active (logically true) and “Logic In 2” is not active (logically false)
XOR
A
Step if “Logic In2” is active (logically true) and “Logic In 1” is not active (logically false)
XOR
b
Step after [Stp Logic Time x] and “Logic In 1” is active (logically true)
TIMED AND
C
Step after [Stp Logic Time x] and “Logic In 2” is active (logically true)
TIMED AND
d
Step after [Stp Logic Time x] and “Logic In 1” is not active (logically false)
TIMED OR
E
Step after [Stp Logic Time x] and “Logic In 2” is not active (logically false)
TIMED OR
F
Do not step OR no “jump to”, so use Digit 0 logic
IGNORE
