This ID is assigned by Siemens for each unique application.
It correlates directly to a particular point list approved at the
time of release. Therefore, this point list shall remain fixed
once approval is granted. Any changes to the point list shall
require a new Application ID and re-approval by Siemens.
The Application ID assigned to the E-Clipse bypass is 2737.

parameters 3001-3003.
PCB TEMP
DEG C of bypass board
KW HOURS
Bypass-mode kilowatt hours
RUN TIME
Bypass mode run hours
A-B VOLT
Phase A - Phase B voltage
B-C VOLT
Phase B - Phase C voltage
C-A VOLT
Phase C - Phase A voltage
OVRD TIME

compatibility with Siemens control systems. It has no
functionality in the bypass application.
MTR RUNNING
This point indicates the system's run status, regardless of
control source (1 = RUN, 0 = STOP).

2.
OVERRID CMD
This point is commanded by FLN to select override 2.
Override 2 is configured by parameters in bypass group 17.
