By selecting the Activate: checkbox, the global reset of error conditions via one of the stan-
dard/A/B slaves connected to the AS-Interface bus is activated.
If a device detects an error, the AS-Interface safety monitor enters the error state. The error
state is locked (error lock). With versions of the AS-Interface safety monitor before 2.0, the er-
ror state can be rectified only by resetting the AS-Interface communication or by resetting the
AS-Interface safety monitor by switching off and then switching back on the AS-Interface safety
monitor or by pressing the Service button on the AS-Interface safety monitor.
As of version 2.0 of the AS-Interface safety monitor, it is possible to differentiate the reset of
error conditions (Reset). Reset of error condition can be activated by an AS-Interface standard/
A/B slave, e.g. a button, and acts only on a device level. Thus, the complete safety monitor is
not reset, but rather only the device locked in the error. For a safety monitor with two indepen-
dent OSSDs, therefore, only that OSSD is reset in which the device locked in the error is con-
figured.
AS-Interface diagnosis
Monitor base address
You can assign an AS-Interface bus address for the AS-Interface safety monitor. In this case,
it is possible to query diagnostic information about the AS-Interface bus from your AS-Interface
master (e.g. the PLC). If you do not assign an AS-Interface bus address, the AS-Interface sa-
fety monitor functions strictly as a "listener", i.e. only as a monitor on the bus. It is not possible
to communicate with the safety monitor via AS-Interface in this case.
For assigned monitor base addresses, you can set under Data selection whether the dia-
gnostic data are to be output via AS-Interface sorted by OSSD or are to be left unsorted (all
devices) (see chapter 7).
Note
When performing diagnostics via the AS-i, the PLC is informed of the indices of the devices
which are switched off. Previously, if a device was added to or deleted from the configuration,
all subsequent indices were shifted. As a result, it was necessary for the user to modify the
diagnostics program in the PLC.
In the Edit menu of ASIMON version 2.1, you can now use the Device index assignment
menu item to freely assign the diagnosis indices to the devices for AS-Interface diagnostics
(see chapter 7.2 "Assignment of the AS-Interface diagnosis indices").
