Diagnostics via AS-Interface
7.1 General procedure
ASIMON V3 - Configuration software for AS-Interface safety monitor
164 Programming and Operating Manual, Edition 09/2008, GWA 4NEB 333 1558 02 DS 02
If the data call changes from (0) to (1), the data set is stored in the AS-Interface safety monitor.
Bit D3 in the answer, however, remains reset until the process is concluded. As a result, the
PLC thinks it has received answers to data call (0). If D3 is set, a consistent data set exists.
If, with the bit D3 set, the answer from the AS-Interface safety monitor signals deactivation of
an output circuit, detailed diagnostic information can now be queried in the stored state with
the specific data calls (2) … (B). Depending on the setting in the configuration of the AS-Inter-
face safety monitor, data calls (4) … (B) return device diagnostic information sorted according
to output circuit (see chapter 7.3.2) or unsorted (see chapter 7.3.3).
A fresh data call (0) cancels the stored state again.
Note
If the AS-Interface safety monitor is in configuration operation, it is not possible to query the
detailed diagnostic information using the data calls (2) … (B).
