Program Methodology—Point Status Indicators
Siemens Building Technologies, Inc. 1-79
When a point is at HAND status, PPCL continues to issue
commands to that point. Since the HOA override switch is controlling
the point, the PPCL commands do not take effect. When the HOA
override is switched back to the AUTO position, the last command
issued to that point, while in HAND status, is executed.
See Table 1-9 for a comparison of the point status while using the
HOA override switch.
Table 1-9. Point Status with the HOA Override Switch.
HOA
Switch
Setting
Point is being
controlled by…
Result
HAND HOA switch Digital points: *ON* or *OFF*
Analog points: Value of the current
HAND position. This value could differ
from the last commanded value.
OFF HOA switch Equipment being controlled is OFF.
AUTO Operator interface
or PPCL
Equipment is being controlled by
operator interface or PPCL.
CAUTION:
Be aware of how your system will react before
attempting to control equipment by using an HOA
override switch. Manually controlling equipment can
cause the system to react in an unstable manner.
Once control is returned to the system, you may
need to perform other functions before normal
operations can resume.
