8.3 Diagnostic messages
The F-CM AS-i Safety ST module generates one or more alarms when various events occur.
Note
When replacing an F-CM AS-i Safety module with firmware V1.0.0, the following must be
observed:
With firmware V1.0.1 or higher, the F-CM AS-i Safety ST module generates a modified range
of alarm messages compared with V1.0.0.
If the user program evaluates the error numbers of the generated alarms directly, the user
program may have to be adapted if the firmware version is changed (e.g. when changing a
device). If necessary, the firmware version of a replacement device can be modified to the
previously used firmware version (see Section "Firmware update (Page 24)").
It is expected that the upgrading of the firmware version from V1.0.0 to V1.0.1 will not usually
have any influence on the user program. The safety functionality of the F-CM AS-i Safety ST
module does not change when the firmware is replaced.
If, after the replacement of a device, an alarm message of the F-CM AS-i Safety module
appears in the message system (e.g. on an HMI panel), which contains an error code
instead of a message text, then the assigned message texts are not known to the message
system. In order to update the message texts, the project must be re-compiled with a current
version of the TIA Portal / STEP 7 and loaded into the controller or into the message system.
The function of the message system can be checked by generating an alarm (e.g. by
removing an assigned AS-i safety slave).
Diagnostic messages for firmware V1.0.0
The following applies for firmware V1.0.0: Which events lead to which alarm messages is
indicated in the description of data record DS 92 "Device-specific diagnostics" (Page 57).
The alarms use the diagnostic codes 0 to 31 according to the PROFIBUS Standard.
Diagnostic messages as from firmware V1.0.1
The following applies as from firmware V1.0.1: Which events lead to which alarm messages
is indicated in the description of data record DS 206 "Data record diagnostics" (Page 69).
The alarms use diagnostic codes in the extended range of values according to the
PROFINET Standard. The alarms allow a meaningful system diagnosis to be made,
specifying the type of error and the AS-i address affected.
