Wiring the host interface (Connecting the PC)
The CLP 100 is operated and configured with the CLP Setup software. For this purpose it
must be connected to the PC via the host interface.
When the PC is connected, the communications parameters are set as described in
.
Figure 5-1
shows the wiring of the RS-232 host interface.
Damage to the interface module in the CLP 100!
Electronic components in the CLP 100 can be damaged if the host interface is wired
incorrectly.
¾
Wire the host interface correctly in accordance with
Figure 5-1
¾
Check the wiring before switching on the CLP 100.
¾
Connect the host interface of the CLP 100 EMC-compatibly to the host by means of
shielded cables (
refer to Figure 5-1
). Observe the maximum cable lengths (
refer to
Table 5-3
,
Page 16
).
Recommendation
¾
Apply the shielding at one end.
1. Switch off the PC and the supply voltage of the CLP 100.
2. Connect the desired port "COM x" of the PC to the CLP 100. To this purpose use an
RS-232 data connection cable (RxD and TxD transposed).
3. Switch on the PC and the supply voltage of the CLP 100.
4. Set the communication parameters of the PC (
refer to Section 10.2.3, Page 34
In the default setting the CLP 100 communicates via the RS-232 interface with the host
using the values listed in
Table 5-4
