Logic Override of the Setting Group Control Function
Setting group selection can be overridden to allow manual setting group selection. Manual setting group
control and selection is achieved through the human-machine interface (HMI) Screen 2.3.1 or by using
the CS/CO-GROUP command. It cannot be achieved using BESTCOMS. The CS/CO-GROUP command
uses select-before-operate logic. A setting group must be selected using the CS-GROUP command
before the setting group is activated using the CO-GROUP command. The process of selecting and then
placing a setting group in operation is summarized in the following two paragraphs:
Use the CS-GROUP command to select the desired setting group. After the CS-GROUP command is
issued, there is a 30 second window during which the setting group can be activated using the CO-
GROUP command.
Use the CO-GROUP command to activate the setting group already selected. The setting group activated
with the CO-GROUP command must match the setting group selected with the CS-GROUP command. If
the setting group specified in each command doesn't match or the CO-GROUP command isn't entered
during the 30-second window, the CO-GROUP command is blocked and an error message is returned.
CS/CO-GROUP commands are executed without having to use the EXIT command to save setting
changes.
When a setting group change is made, any subsequent setting change is blocked for two times the
duration of the SGC alarm output time setting. Refer to the Setting Groups subsection for more
information about SGC Alarm settings.
CS/CO-GROUP Command
Purpose: Read or change logic override settings for setting group selection.
Syntax: CS-GROUP[=<mode>]
Comments: mode =Setting Group 0, 1 or L. L returns group control to the automatic setting group
logic. <mode> entry of CS-GROUP command and CO-GROUP command must match or
setting group selection will be rejected. If more than 30 seconds elapse after issuing a
CS-GROUP command, the CO-GROUP command will be rejected.
CS/CO-GROUP Command Examples:
Example 1. Read the current status of setting group override.
>CO-GROUP
L
Example 2. Override logic control and change the active setting group to SG1.
>A=password (Gains access)
>CS-GROUP=1
GROUP=1 SELECTED
>CO-GROUP=1
GROUP=1 EXECUTED
Example 3. Return control of the active setting group to the automatic setting group logic.
>CS-GROUP=L
GROUP=L SELECTED
>CO-GROUP=L
GROUP=L EXECUTED
>EXIT (Quits access)
Retrieving Setting Group Control Status from the Relay
The active setting group can be determined from HMI Screen 1.5.5 or by using the RG-STAT command.
Section 6, Reporting and Alarm Functions, General Status Reporting, provides more information about
determining the active setting group. The active group can also be determined using BESTCOMS
Metering screen.
Logic override status can be determined from HMI Screen 2.3.1 or through the RG-STAT command.
Section 6, Reporting and Alarm Functions, General Status Reporting, provides more information about
determining logic override status. Logic override cannot be determined using BESTCOMS.
