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. 35 shows the connection of the digital inputs. Special attention must be paid to the
wiring with the correct terminals. In this example the height sensor is connected to
terminal 1, the first light barrier to terminal 2, the colour sensor to terminal 3 and the
second light barrier to terminal 4. No shielded cable is used. The connection is carried
out according to chapter 5.5.1 "Connection of the digital inputs".
