AVENTICS | DDL | R499050020–BDL–001–AD
Missing solenoids can be determined when the system is
switched on. In cyclical operation, diagnostic messages are
only sent if there have been any changes. "Open load" is
reported immediately and the valve does not have to be
controlled.
W
Bit 3 = 0: If the bus coupler malfunctions, the output data in
the valve system will be set to 0.
W
Bit 3 = 1: If the bus coupler malfunctions, the output data in
the valve system will be stored and the solenoids will
continue to be controlled (freeze values).
Changed parameters only become effective when the
device is switched off and then on again or if it is initialized.
