If a COLBAS Pool number is given in a Maintenance Reaction entry the respective
measured operating hours are added to the specified Pool value approximately every 5
minutes. There, the accumulated total is always available to any COLBAS program for
further processing
(Statement: DIM #k= v(x,y), where k=COLBAS Pool number as per the Maintenance
Reaction entry).
Manual changes to the accumulated count do NOT influence the COLBAS Pool variable
value! If necessary the COLBAS Pool variable can be changed to another value through
a COLBAS program.

A VISONIK Server can only measure the number of hours a point is in operation if every
change of the related point's status is reported to the Server.
This can only be carried out in DC Server mode OPMO=C,Cf,CfR.
When OPMO=DSb,DSbe, the hours counted as held in parameters OH1, OH2, OH3,
OS1, OS2, OS3 as well as configuration parameter OPS are taken from the respective
process station.
In process stations (PS) fitted with EKL-X/S Controllers, points can be operated (under
parameter OPMO = Operating Mode) such that only error states are reported to the DC
Server (but no operating hours) which therefore makes counting of operating hours
impossible
.
However, EKL-X/S controllers can measure operating hours locally (parameters
OPS/OHx/OHR).
The locally measured operating hours are then automatically used in a central
Maintenance Reaction Register under the following conditions:
•
process station is of the EKL-X/S-Controller type.
•
The related point must be type SC (=Switch command) or ST (=Status).
•
Parameter OPMO for the point involved must be set to "Local".
•
The local point status to be registered (OPS) must agree with that in the relative MRR
entry.
Now, when the occasion arises, but at least once per day the local EKL measured
difference in operating hours will be transmitted to the Server and added to the
operating hours counter in the respective MRR entry.
If the above conditions are not fulfilled the Server's MRR entry has no function!
Local (EKL) operating hours counting is indicated in a MRR listing by the abbreviation
"(PS)" printed in front of the "ACCU" hours counter.
