When a monitored event occurs or a monitored variable changes state, the SER logs the time and date of
the event, the event or variable name, and the state that the variable changed to. For user-programmable
logic variables (contact sensing inputs, virtual switches and virtual outputs), the user-programmed
variable name and state names are logged in the SER report instead of the generic variable name and
state names. For more information, refer to Section 7, BESTlogic Programmable Logic, User Input and
Output Logic Variable Names.
Retrieving SER Information
SER information is retrieved through SER Directory Reports, the New Events Counter, and by obtaining
specific SER Reports.
SER Directory Report
A directory report lists the number of events currently in memory and the time span that the events cover.
Directory reports are accessed using the RS (report SER) command.
New Events Counter
The new events counter tracks how many new entries have been logged to the SER since the new
events counter was reset to zero. After SER information is checked, the new events counter can be reset.
Then, the next time that the relay is checked, it is easy to determine if there are new events that haven't
been evaluated. One line of an SER directory report contains the new events counter information. The
new events counter is reset by obtaining write access to Reports and using the RS=0 command. The new
events counter can be viewed but not reset at HMI Screen 4.2.
SER Report
A directory of SER reports can be obtained using the RS (report SER) command. Six sub-reports are
available through the RS command: RS-n, RS-Fn, RS-ALM, RS-I/O, RS-LGC, and RS-NEW. These sub-
reports give specific types of data without confusing the user with every internal state change and event
occurrence. Each sub-report is defined in the following paragraphs:
1. RS-n (report SER, number of most recent events)
Events are retrieved for the most recent entries. Entering RS-4 would view an SER report for the
last four events.
2. RS-F<n> (report SER, for Fault <event number>)
Events are retrieved for the period of time specific to a fault event. The report includes all events
within the time span of the fault plus one event before and after the fault. Entering RS-F9 views a
SER report associated with fault record 9.
3. RS-ALM (report SER, alarm)
This command retrieves all alarm events that exist since the last RS=0 command was issued.
(RS=0 resets the new records counter to zero.) This information can also be obtained using the
RA-SER command.
4. RS-IO (report SER, input/output)
This command reports all input and output events since the last RS=0 command was issued.
(RS=0 resets the new records counter to zero.)
5. RS-LGC (report SER, logic)
A report is retrieved for all logic events since the last RS=0 command was issued. (RS=0 resets
the new records counter to zero.)
6. RS-NEW (report SER, new events since RS=0 reset)
Events are retrieved for the period of time covered by the New Events Counter register.
RS Command
Purpose: Read/Reset Sequence of Events record data.
Syntax: RS-<n>, RS-F<id>, RS-AL, RS-IO, RS-NEW
Comments: <n> = number of events to be retrieved
<id> = fault record number to be retrieved
