The operating hours count can be installed for the point types of physical basic
functions "signalling" and "switching" as well as for virtual digital point types to integrate
subsystems:
Point
type
Brief description OH... RT...
ML Status signal (digital input) x
SB1 1-step switching command x
SBR1 .. 3 1- to 3-step switching commands, with feedback x
DI Digital Input; link point to adopt data x
DO Digital Output; link point to transfer data x
RWI AEROGYR ventilation controller RWI on FLN bus x
SEZ MONOGYR switching unit SEZ81… on M-bus x
Activation and control of operating hours count occurs via the corresponding
parameters
of the respective points. The parameters have designation:
– OH... (for Operating Hour) with physical basic functions
– RT... (for Run Time) with link points, MONOGYR, and AEROGYR points
Below is a short description of the operating hours count functions:
Function Description
Activate operating hours
count
Activation occurs by setting the corresponding parameter
in the respective point such as:
OHACT=1 for point type ML; RTACT=1 for point type DI
Add operating hours
count
The corresponding parameter contains the added
operating hours for point or operating states.
Range: 0.00 .. 65534.99 hrs at OH... / 0 ..1E36 at RT...
Define limit value The corresponding parameter defines the operating hours
limit value.
Compare operating hours
to limit value
On limit value violations, the corresponding error state
(OPSTA=13) of the respective point in the BPS is set.
If the BPS itself is supposed to trigger such action on limit
violations, programming is required (COLBAS task).
Transfer operating hours
to DCS
Defines the intervals at which a transfer is supposed to
occur. Value range: 0, 0.25, 1.00, 24.00 hrs
Range limits
(for DI, DO, RWI, SEZ)
For multi-stage point states, two point status ranges can be
defined during which operating hours are acquired.
All involved parameters can be queried at the VISONIK BPS. BPS reactions occur only
if they have been programmed in a COLBAS task.
