ASCII Command Reference
Command Description
SER CV and SER RV
The SER CV and SER RV commands clear any SER data records that have been
viewed from the present port. The two commands are equivalent.
If you issue the SER CV or SER RV command, the relay prompts you with
Clear viewed SER records for this port. Are you sure (Y/N)?. If you
answer Y <Enter>, the relay clears all SER records viewed from this port. The
data are still visible to other ports and to file transfer accesses, and they must be
cleared independently for those ports. Data not yet viewed remain available.
SER D
The SER D command shows a list of SER items that the relay has automatically
removed. These are “chattering” elements. You can automatically remove chat-
tering SER elements in the SER Chatter Criteria category of the Report settings;
the enable setting is ESERDEL.
If you issue the SER D command and you have not enabled automatic removal of
chattering SER elements (Report setting ESERDEL), the relay responds,
Auto-
matic removal of chattering SER elements not enabled
.
SET
Use the SET command to change relay settings. The relay settings structure is
ordered and contains these items (in structure order): classes, instances, catego-
ries, and settings. An outline of the relay settings structure is as follows:
Classes (Global, Group, Breaker Monitor, Protection, Automation, Outputs,
Front Panel, Report, DNP3, and Ports)
Instances (some classes have instances: Group = 1–6; Protection = 1–6;
Automation = 1–10; PORTs = 1–3, F, 5)
Categories (collections of similar settings)
Settings (specific relay settings with values)
The SET and SHOW commands contain these settings structure items, which
you must specify in order from class to instance (if applicable) to setting. The
order that specific settings appear in the relay settings structure is factory pro-
grammed.
