System manual CECX / System overview
3.2 Working mode of the control
3.2.1 Program processing
The control operates according to the following principle: “Reading Inputs,
Processing, writing Outputs”. The CECX modular control system carries out
the following tasks during processing of each task defined with CoDeSys:
Reading inputs:
The actual states of the inputs are read at the start of a cycle and writ-
ten into the process map of the inputs.
Processing:
The user program is being executed. The target state of the outputs is
copied into the process map.
Writing outputs: At the end of the cycle the target states of the outputs
stored in the process map are transferred to the physical outputs.
3.2.2 Configuration and addressing
The CECX modular control system can be made up of a host of modules
and linked with additional external devices.
The expansion of the CECX modular control system and its connected de-
vices is fixed during configuration in CoDeSys. The available I/O channels
are displayed in the control configuration of CoDeSys and can be used in
the CoDeSys application.
The CECX modular control system can be expanded with add-on modules.
External devices can be connected via serial interfaces and field buses
(onboard or via option modules).
