NETWORK_IN
This functional block implements a Network connection
input interface; it generates an LL1 in the OUT output
when the line is high, otherwise an LL0.
Parameters
Type of input:
- Single - enables the connection of Signalling outputs of an external MZERO unit.
- Double - enables the connection of OSSD outputs of an external MZERO unit.
Filter (ms): Enables the filtering of signals from an external MZERO unit.
This filter can be set to between 3 and 250ms. The length of the filter affects the calculation of
the unit's total response time.
➔ This input must be used when MZERO OSSD outputs are connected to the inputs of a second
downstream MZERO or together with the NETWORK operator.
SENSOR
The SENSOR function block verifies the status of the
input of a sensor (not a safety sensor). If the beam of the
sensor is occupied (sensor output FALSE) the output is 0.
Otherwise, with the beam clear and an output of 1 (TRUE)
then the output is 1.
Parameters
Manual reset: If selected this enables the request to reset
each time the area protected by the sensor is occupied.
Otherwise, enabling of the output directly follows the
input conditions.
There are two types of reset: Manual and Monitored.
When Manual is selected the system only verifies the
signal's transition from 0 to 1. If Monitored is selected the double transition from 0 to 1 and then
back to 0 is verified.
➔ If the Manual Reset is active, a consecutive Input have to be used. Example: Input 1 is used
for the functional block, then Input 2 have to be used for the Reset Input.
