Controller structure
The controller has a modular structure. It essentially consists of:
-
a central module,
-
optional modules (in plug-in slots in the central module),
-
peripheral modules (installed to the right of the central module).
1.2.1
Central module
The central module is the centrepiece of the controller CECX-K-D1. It provides the neces-
sary resources for executing the application software (processor, RAM, etc.).
The central module offers three slots for optional modules that offer further connections
for interfaces to the central module. Three peripheral modules for extending the function
are installed on the right side of the central module.
