Step 2: Connecting the power supply
As described in Chapter 5.4 "Electrical connection of the device", the power supply is
connected to the controller.
13.4
Step 3: Programming the PLC
For programming, the controller is connected to a computer via the Ethernet interface.
The PLC is programmed using the EX_PRESS 5 software. After successfully compil-
ing and fitting the program code, it can be transferred to the control (see chapter 1.6.2
"Calling the programming tool" in the EX_PRESS 5 manual).

Step 4: Connecting the inputs
Fig.32
shows
the
connection
of
the
digital
and
analog
inputs.
Special attention must be paid to wiring with the correct terminal.
In this example, terminal 1 is the light barrier 1, terminal 3 is the light barrier 2,
terminal 5 is the push button switch and terminal 7 is the proximity switch. No shielded
cable is used for this purpose. The connection is made according
to
chapter
5.5.2
"Connection
of
the
digital
inputs".
