ASIMON V3 - Configuration software for AS-Interface safety monitor
Programming and Operating Manual, Edition 09/2008, GWA 4NEB 333 1558 02 DS 02 63
Description
With the double channel conditionally dependent monitoring device, both switching signals
of the respective safe AS-Interface slave each act on 2 bits of the transmission sequence. In
order for the second, dependent switching signal to be accepted in this case, the first switching
signal must be present. Which contact is dependent on which can be freely selected. It is an
error if the second, dependent switching signal arrives before the first switching signal.
Example: A door switch with locking. One contact is operated by the door switch (independent
contact), the second by the lock monitor (dependent contact). Only if the door is closed, the
lock can be opened and closed. An opened door contact with the lock closed is an error.

Caution
Double channel conditionally dependent monitoring devices offer only limited safety, as they
cannot be checked for simultaneousness. Check carefully to ensure that the use of a double
channel conditionally dependent monitoring device fulfils the requirements of the desired sa-
fety category.
Example: Contact with bit address In-1 is the independent contact
0026 INDEX: 33 = "Name"
0027 TYPE: 25 = double channel priority safety input
0028 SUBTYPE: in-1 is independent
0029 ASSIGNED: channel one
0030 SAFE SLAVE: 4

Example: Contact with bit address In-2 is the independent contact

0021 TYPE: 25 = double channel priority safety input
0022 SUBTYPE: in-2 is independent
