4.13.2. Input elements
Figure 138 List of input units
Input elements create the digitial connection between one or more connected sensors or other
subordinate switching devices in the SCU system. They provide data about the operating status of
the plant that is monitored by the SCU module. These components, which, from the point of view of
the SCU module, are situated outside the device, can be added or configured only in the terminal
scheme or in the circuit diagram. Except the operation mode switch, every input element provides
a logic output signal
“0” or “1” for further processing in the SPC. The units are structures according
to their application, and according to the type of the input signal. Thus, a targeted resource
monitoring of the SCU module is possible. The input blocks are structured according to their
application (e.
g. “Enable” button).
The following paragraphs contain deta
ils about this type (e. g. the “Confirm“ button
).
