1. Purpose of <strong>PC</strong> <strong>Control</strong> <strong>645</strong>-<strong>12M</strong><br />
Introduction<br />
Automation more and more frequently relies on the use of<br />
<strong>PC</strong>s which are applied either for process visualisation and<br />
data acquisition or even for control operations.<br />
<strong>PC</strong> <strong>Control</strong> <strong>645</strong>-<strong>12M</strong>, a PLC in the shape of <strong>PC</strong> slot card,<br />
corresponds to this trend.<br />
2 Models<br />

<strong>PC</strong> <strong>Control</strong> <strong>645</strong>-<strong>12M</strong> <strong>645</strong>.425.11<br />
-- with 24 V DC external power supply:<br />

<strong>PC</strong> <strong>Control</strong> <strong>645</strong>-<strong>12M</strong> NT <strong>645</strong>.425.10<br />
In the following chapters we are using the term "<strong>PC</strong> <strong>Control</strong><br />
<strong>645</strong>-<strong>12M</strong>" synonymously for both device types. Text passages<br />
making reference to the differences between the two<br />
are marked.<br />
Tasks<br />
-- as a PLC, the device is used for process control relying<br />
on PROFIBUS for signal and data exchange with processlevel<br />
components or other controllers<br />
-- if used in a <strong>PC</strong> environment, it interacts with the <strong>PC</strong>, serving<br />
as process control system and interface between the<br />
process to be controlled on the one hand and process<br />
visualisation and process data processing on the other<br />
