Failure Management

The failure management system concept implemented in CP-8000/CP-802x ensures the indi-
vidual identification of data of failing system components and the correct system and process
behavior in disturbance events. For this purpose, the failure management function includes
·
a system function for failure detection (for instance for modules, communication)
·
derived therefrom a system signaling in the form of status information in spontaneous
messages and in the form of special data points for the open-/closed loop control function
·
a parameter-settable behavior of I/O Master Modules with output function.
This way, the state for each process information is available at all data sinks (peripheral out-
puts, open-/closed-loop control function, process control system), and it is possible - depending
on the requirement and functionality - to elicit an appropriate counterreaction therefrom.
3.1.11

Diagnostics and Signaling

The diagnostics function manages the system states and error information detected by the
various functions and their watchdogs. It permits the indication of the internal system and error
information, and of the process states by means of the engineering tool.
System and error states are filed in tables as current and saved information. This information
can be displayed in detail locally and from remote locations. The saved information can be
acknowledged and can therefore be updated again. For the sake of better clarity, these tables
are divided into various classes.
The internal I/O Modules supply the detected system and error states together with additional
information (for instance cause of error, originator description).
A sum information about the detailed errors is transmitted via the communication to the clos-
est automation units, where it is managed.
Important detailed and sum information is indicated by means of LEDs, process states via the
display at the front panel.

Storage of Application Data

With engineering via the SICAM TOOLBOX II, application data are stored in a data base on
the engineering PC. From there they can be loaded into a target system, or else be written on
a suitable SD card.
With engineering via the web browser, application data are written directly on the SD card in
the target system.
The application data of a project created via the web browser can be saved in a file on the en-
gineering PC. With the aid of the program Sicam_first_startup this data can be written on a
suitable SD card (for instance for the duplication of a project).
After putting a written SD card into a target system, the target system transfers changed or
added data into its main memory during a subsequent startup.
