Unit Description
SetOn
SetOff
Act
En
On/Off Ctrl
A0034234-EN
This unit represents an on/off controller.
The input ports
SetOn , SetOff and Act adopt the largest numeric data type of all the output ports that
are connected to one of these input ports.
The unit switches its Boolean output port on or off if the value of the input port
Act exceeds or drops
below the values of the input ports SetOn and SetOff respectively. The Boolean input port En can be
used to enable the unit. If the value is 0 , the output port is always 0 .
If SetOn = SetOff , the unit behaves as illustrated in the diagram below. The output port is switched on
when Act > SetOn . The output port is switched off when Act ≤ SetOff .
SetOn = SetOff

A0034326
If SetOn > SetOff , the unit behaves as illustrated in the diagram below. The output port is switched on
when Act ≥ SetOn (broken blue line). The output port is switched off when Act ≤ SetOff (solid blue
line).

If SetOn < SetOff , the unit behaves as illustrated in the diagram below. The output port is switched on
when Act ≤ SetOn (solid blue line). The output port is switched off when Act ≤ SetOff (broken blue
line).

Stop
OpenVPN
A0034235
This unit can be used to control the OpenVPN client.
The client is started when the Boolean input port
Start switches from 0 to 1 . The client is stopped
when the Boolean input port Stop switches from 0 to 1 .
The Boolean output port Running indicates whether the client is running. The Boolean output port
Connected indicates whether the client is connected to a server.
Or
A0034237-EN
This unit performs a binary OR. The operation is performed in the largest integer data type of all the
output ports that are connected to the input ports of the unit. All the ports of the unit adopt this data
type. Input ports connected to floating point or string output ports are treated as if they were
connected to a 32-bit signed integer output port.
