5.4.4
Wiring the terminal interface
As an alternative the PC may be connected to the terminal interface.
Figure 5-2
shows the wiring of the terminal interface.
Note
The terminal interface is a TTL level interface.
5.4.5
Wiring the "Sensor" switching input
If a reading process is to be triggered via an external sensor, connect the sensor to the
"Sensor" switching input. This triggering type is selected as the default setting of the CLP
100.
Figure 5-3
shows the wiring of the "Sensor" switching input.
Table 5-5
lists the
characteristic data of this switching input.
