SICK Flexi Compact User Manual

Synchronization time
T
he synchronization time is the amount of time for which the two inputs are allowed to
have different values.
Fixed value: 500 ms in accordance with EN 574
Sequence monitoring
T
he Enable output is set to 1 if both inputs were inactive at the same time for at least
the logic execution time before being activated.
If the Enable output = 1 and then at least one input becomes inactive, then the Enable
output = 0.
Complementary information
Dif
ferent propagation times of the input signals can lead to a lengthening or shortening
of the synchronization time.

Overview
T
his function block provides the logic for monitoring the inputs of a two-hand control
device. The category 1 (Type IIIA) or category 4 (Type IIIC) according to EN 574 depends
on the wiring and parameterization.

Output Description
Enable Data type: Boolean
•
0 = no
t enabled
•
1 = enabled
The Enable out
put is set to 1 if the following conditions are met:

Bo
th input pairs are inactive at the same time for at least the
duration of the logic execution time
°
Both input pairs are then active
Status input pair 1 Data type: Boolean
•
0 = Er
ror
Input pair has not gone into a complementary status within the
discr
epancy time.
•
1 = N
o error or unknown
Status input pair 2
Synchronization status Data type: Boolean
•
0 = Er
ror
Synchronization time exceeded.
•
1 = N
o error or unknown
