7.17 Alarms
The DSB blocks report alarms based on the standard and/or extended diagnostic data received from the slave
devices. The following are the standard alarms generated by all DSBs.
• Communication break with PROFIBUS slave
• PROFIBUS slave configuration failure
The following table lists the generic DSBs that supports user-defined alarms and also the number of alarms
supported by each DSB.
DSB name
Number of user-defined alarms supported
GENDSB
34
GENIODSB
130
GENPADSB
16
GENPAGWDSB
132
Drive DSB
16
You can configure alarms to parse single bit, multi bit, and multi byte field from slave extended diagnostic data
and compare it with a given reference value. If the comparison with the given reference value is true, then an
alarm is reported with configured priority and severity. One user-defined alarm can be configured to parse a
maximum of 32 bits in extended diagnostic data.
You can also configure the priority and severity for each user-defined alarms.
With R410, Generic DSBs are enhanced such that in addition to reporting an alarm, you can choose to set the
status of individual channels to either “Good” or “Bad” based on your requirement and as per slave extended
diagnostic. For example, you can choose to set the status of the 8th channel of the 5th PDC to “BAD” based on
your requirement.
In R400, individual channel level status setting was not supported by the GENDSB. Either all channels were set
to “Good” or all channels were set to “Bad.”
Refer to the section “DSB block diagnostic alarms” on page 175 for information on the alarms generated by the
DSB blocks.
Alarms supported by GENPADSB
GENPADSB supports alarming based on diagnostics data defined in Profibus PA profile.
Note that PA profile diagnostics do not set the channel status or the PDC status as abnormal.
The
Extended Diagnostics
tab in the Monitoring view displays details of each diagnostic data of the
GENPADSB.
Alarms supported by GENPAGWDSB
GENPAGWDSB supports alarming based on diagnostic data received from Siemens IM-157 DP Link. For best
coverage, you must configure 160 byte diagnostics data length while configuring the
Parameters
page for
IM-157, which contains separate sections for Module diagnostic, module status, GW diagnostics and PA slave
diagnostic.
Note that IM-157 diagnostics activity do not set the channel status or the PDC status as abornmal.
The
Extended Diagnostics
tab in the Monitoring view displays details of each diagnostic data of the
GENPAGWDSB.
