Configurable I/O modules

Function modules generally have a configuration which is defined by their firmware and which can be modified to a certain extent by plug-in jumpers (e.g. inversion of manipulated vari- able, internal/external definition of setpoint etc.).

The standard system software of the AS 235 automation system also contains driver blocks for configurable function modules from the device spectrum of the TELEPERM ME process control system for power plants. In this case, the firmware of these mod- ules contains an interpreter which processes a user configura- tion generated using defined blocks. This user configuration is produced on a personal computer in the STEP M (BG) language, loaded into the module via a serial interface, and stored in an

EEPROM.

This principle enables the implementation of highly flexible, indi- vidual concepts on the modules for process-oriented prepro- cessing with direct intervention into the process whilst bypassing the automation system. Likely applications are e.g. balanced backup structures or particularly time-critical process operations.

An example of a configurable signal module is the analog input module 6DS1 731-8RR for temperature signals. The required data on the type of transmitter, measuring range, cold junction etc. must be defined by configuring for the input channels (max. 32, basic module and 2 extension modules). The config- uring data for this module are stored in a flash-PROM.

The STRUK-AS 220 EA program is required for loading/config- uring (see page 4/6).
