Output
Description
Enable
Data type: Boolean
Resets the safety device.
•
When the
Release
input = 1 and the function block detects a valid
restart pulse on the
Restart
input, the
Enable
output switches to 1.
•
The
Enable
output remains = 1 as long as the
Enable
input = 1.
Restart required
Data type: Boolean
The output pulsates at 1 Hz to indicate that the function block is
expecting a valid restart pulse at the
Restart
input so that the
Enable
output can switch to 1.
When the
Release
input = 1 and the function block detects a rising
signal edge at the
Restart
input, the
Restart required
output switches
permanently to 1.
You can use this output to control an indicator lamp.
Ready for restart
Data type: Boolean
The output switches to 1 when a valid pulse at the
Restart
input leads to
activation of the
Enable
output.

Complementary information
To evaluate the minimum length of the restart pulse (here: 100 ms), the restart signal
must be sampled twice after a 0→1 transition is detected. The required minimum
length of the restart signal is therefore extended by one logic execution time.

Multi operator V1
Overview
You can use this function block to operate up to three two-hand control devices at the
same time (e.g., for press applications with more than one operator).
