F 3221 Hima HIQuad X Safety-related Input Module

Safety-related inputs may be used for safety-related as well as for non-safety-related signals. Non-safety-related signals, however, may not be used for safety functions!

The safety-related input modules without processor system are automatically subjected to a high-quality, cyclic self-test during operation. The input modules include wiring elements

ensuring that the module function is tested with special test routines integrated in the operating system (I/O processing module). These test routines ensure the safe functioning of the corresponding input module.

Detection of faults during the self-tests automatically triggers a safety-related response of the I/O processing system and generates the corresponding error messages. The detailed error messages can be evaluated in the user program by reading out the error codes. To ensure the module's proper operation, HIMA cable plugs must be used.
