Command Syntax
Siemens Building Technologies, Inc. 3-37
DISCOV (Disable COV)
Unitary pre-APOGEE APOGEE BACnet
Syntax
DISCOV(pt1,...,pt16)
pt1
through
pt16
Point name that should not report updated changes-of-value
(COV).
Use
Stops devices from reporting updated values (COVs) to the Insight
workstation. When this command is executed, all operations that use
COVs to function will stop.
Until the points defined in this command are enabled, updates to
graphics, archiving, COV printing, alarming, and in some cases
evaluation of equations, will stop.
A maximum of 16 points can be controlled with one DISCOV
command.
Notes
Points defined in the statement must reside in the same device as
the DISCOV command.
Example
50 IF (SFAN.EQ.OFF) THEN DISCOV(ROOM1, ROOM2)
ELSE ENCOV(ROOM1,ROOM2)

DPHONE (Disable phone)
Unitary pre-APOGEE APOGEE BACnet
2.1 only
Syntax
DPHONE(pn#1,...,pn#16)
pn#1
through
pn#16
Telephone ID numbers that are defined in the device.
Use
Disables telephone ID numbers. The telephone ID number is a
numeric code that represents the actual telephone number defined in
the device.
A maximum of 16 telephone number IDs can be disabled with one
DPHONE command.
Example
532 DPHONE(1,2,3,5,6)
Notes
Do not use the DPHONE command over the network.
