INPUT OBJECTS
E-STOP (emergency stop)
E-STOP function block verifies an emergency stop
device inputs status. If the emergency stop button has
been pressed the output is 0 (FALSE). If not the output
is 1 (TRUE).
Parameters
Input type:
- Single NC – allows connection of one-way
emergency stops
- Double NC – allows connection of two-way
emergency stops .
Manual reset: If selected this enables the request to
reset each time the emergency stop is activated.
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.

WARNING: If the Manual Reset is active, a consecutive Input have to be used. Example: Input 1
and Input 2 are used for the fuctional block, then Input 3 have to be used for the Reset Input.
Output test: This is used to select which test output signals are to be sent to the emergency
stop (mushroom pushbutton). This additional test makes it possible to detect and manage
any short-circuits between the lines. This additional control permits detection and
management of any short-circuits between the lines. To enable this control, the test output
signals must be configured (amongst those available).
Test at start-up: If selected this enables the test at start-up of the external component
(emergency stop). This test is performed by pressing and releasing the pushbutton to run
a complete function test and enable the output. This test is only requested at machine
start-up (when the unit is switched on).
