| This site is
intended to provide support for users of Programmable Logic
Controllers in the Research Sector.
The supported PLCs are primarily the general purpose PLCs of the
manufacturers selected by the CERN PLC Working Group:
- Siemens (contract CERN-SIEMENS. B1130A/GEN 01-08-1999);
- Schneider (contract CERN-SCHNEIDER. B1129/GEN 12-11-1999);
We were supporting as well the Wago bus controllers for the low
cost small projects.
In addition to general information about PLCs, developers can find
examples describing how to program PLCs, to access special devices
from PLCs, to integrate PLCs in the experiment Detector Control Systems (DCS) and FAQ.
The section helps users in:
- Selecting the proper PLC hardware;
- Using the programming environment;
- Using special libraries;
- Integrating the PLCs in DCS.
Running PLC-based applications are demonstrated in the IT-CO-FE
Show Case. A set of hardware component is available in the Hands-on
for users wishing to do practical exercises.

The IT-CO-FE section acts as a first line support for the research
sector, a CERN-wide support is offered, for the two recommended
PLCs, by AB-CO-IS.
