TWO-HAND (bimanual control)
The TWO HAND function block verifies the status of the
inputs of a two hand control switch. Only if both the
press-buttons are pressed within 500 ms the output is 1
(TRUE). Otherwise the output is 0 (FALSE).
Input type:
- Double NO Allows connection of two-hand switch
with one NO contact for each button (EN 574 III A).
- Quadruple NC-NO - Allows connection of two-hand
switch with a double NO/NC contact for each button
(EN 574 III C).
Quadruple NC/NO correct connection
 Contacts NO to terminal corresponding to IN1, IN3
 Contacts NC to terminal corresponding to IN2, IN4
Parameters
Output test: This is used to select which test output signals are to be sent to the component
contacts. 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.
This test is performed by pressing the two buttons (within 500 ms) and releasing them 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).
Filter (ms): This is used to filter the signals coming from the mode selector. The filter can
be configured to between 3 and 250 ms and eliminates any bouncing on the contacts. The
length of the filter affects the calculation of the unit's total response time.
Enable Error Out: If selected reports a fault detected by the function block.
Item description: This allows a description of the component's function to be entered. The
text is displayed in the top part of the symbol.
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 M1/M1S unit.
- Double - enables the connection of OSSD outputs of an external M1/M1S unit.
Filter (ms): Enables the filtering of signals from an external M1/M1S 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 can only be allocated on M1

This input must be used when Mosaic OSSD outputs are connected to the inputs of a
second downstream Mosaic or together with the NETWORK operator.
