21 R C S OR AS-Interface Safety at Work The diagnostic function of the AZM 200 solenoid interlock The operating condition of the solenoid interlock as well as possible failures and faults are signalled by means of three-colour LED’s, installed to the front of the device.

The energy for the locking solenoids is supplied separately (Aux). The connection to the AS-Interface system is realised by means of an M12 connector with A-coding. Solenoid control The control system with the AS-Interface Master can lock and unlock the solenoid interlock through output bit DO 0 of the AS-i slave AZM 200 AS. Reading the parameter port Parameter ports P0 to P3 of the solenoid interlock can be read out through the control interface of the AS-i master (see component description) by means of the “Write parameter” instruction (with hexadecimal value F). This (non-safe) diagnostic information from the answer to a “Write parameter instruction” can be used by the user for diagnostic purposes or for the control programme.
