Simulate slaves
If less than four safe or unsafe AS-Interface slaves are connected to the AS-Interface bus, you
must set Simulate slaves to zero in order for the AS-Interface safety monitor to function
correctly.
The number of simulated slaves can be 1 (for large AS-Interface networks) or 3 (for small
AS-Interface networks).
If the Simulate slaves function is activated (number of simulated slaves: 1 or 3), the state of
the relay- and message outputs can be queried by the AS-Interface master (PLC) via the
AS-Interface at monitor base address+1, data bits D3… D0. Bit state 0 identifies an inactive
output, bit state 1 an active output, corresponding to the substitute value in the process image
of the AS-Interface master.
According to this, the AS-Interface safety monitor occupies a different number of bus
addresses in the AS-Interface network:
Note
If Simulate slaves is set unequal to zero, either 1 or 3 additional AS-Interface slaves are
simulated internally. These slaves are automatically assigned the first or first three bus
address(es), respectively, which follow on the AS-Interface safety monitor.

Number of

addresses
Meaning
0No bus address was assigned to the AS-Interface safety monitor. No communi-
cation and, thus, no diagnostics possible via AS-Interface with the safety moni-
tor.
1One bus address was assigned to the AS-Interface safety monitor. Diagnostics
possible via AS-Interface with the safety monitor. Number of simulated slaves
equal to 0.
2One bus address was assigned to the AS-Interface safety monitor. Diagnostics
possible via AS-Interface with the safety monitor. Number of simulated slaves
equal to 1. State of relay- and message outputs can be accessed via AS-Inter-
face at monitor base address+1 (monitor version 2.12 and higher).
4One bus address was assigned to the AS-Interface safety monitor. Diagnostics
possible via AS-Interface with the safety monitor. Number of simulated slaves
equal to 3. State of relay- and message outputs can be accessed via AS-Inter-
face at monitor base address+1 (monitor version 2.12 and higher).
