HIMA F3226 Digital Input Module

Safety and Availability of Safety-Related Input Modules

Due to their high complexity, some types of analog and digital input modules modules have their own 1oo2 microprocessor system that automatically performs safety-related tests during operation and provides safe data to the safe processing unit.

The safety-related input modules allow the diagnostics to be displayed and therefore the faults to be identified and located.

In safety-related systems, both safety-related and interference-free input modules can be used with mixed component configurations.

During operation, safety-related input modules automatically perform high-quality, cyclic selftests within the H41q and H51 systems. The input modules include wiring elements ensuring that the input module function is tested with special test routines integrated in the operating system. These test routines are TÜV-tested and ensure the safe functioning of the corresponding module. If faults are detected, error messages are displayed. Detected faults automatically trigger a safety-related reaction of the system. The error messages are diagnostic information for the operator. It is thus possible to flexibly create a diagnostic system when planning and implementing the system.

To increase availability, the safety-related input modules can also be used redundantly.

The use of redundant input modules does not affect the system safety.

Safety-related input modules can be used for both safety-related signals and non-safety-related signals.

The following conditions must be observed when using the slots permitted for input modules within the system subracks, and the H41q and H51q systems within the I/O subracks:
