with a delay max. 100ms. The fast part is intended for fast changing values as e.g. currents, voltages or 
power. The parts are separated by a line in the record content list. 
 
 
 
1.  Values selection tree  
2.  Buttons for adding/removing values into/from the record structure  
3.  Buttons for ordering of the values in the record structure  
4.  Fast history separator. The fast part is located above the separator  
5.  Estimated number of records depending on record size  
6.  Record capacity usage indicator  
NOTE: 
Values that are displayed in green color are recomended to be placed in the fast part. 
If the checkbox Add modules to history automatically.. in the Modules tab is checked then all values of a 
module are automatically added into the history record when the module is inserted into the configuration. 
Time Stamp function 
The  controller  allows  user  to  define  when  the  history  records  are  written  even  though  there  is  no  other 
reason for history record (so called Time Stamp). 
It  is  possible  to disable time stamping  function (for example  when time  stamping  is  not  needed  and  just 
floods the history). It may be conditioned by activation of logical Binary Input function (TIME STAMP ACT) or it 
may be enabled always. 
Period of time stamping may be adjusted from 1 to 240 minutes. 
NOTE: 
Beware of History flooding by to many Time Stamps (vital information may be overwritten). 
Time and Date Intercontroller Sharing 
Time and Date are used mainly for History records. These values are shared between controllers that are 
connected to CAN. When the value is changed in one controller, it sends its new value to all other controllers 
that are connected to the same CAN bus and they update their time and date values and setpoints 
accordingly. 
Summer Time Mode 
Summer Time Mode function may be enabled and disabled by user. It is possible to set if the controller is 
located in the northern or southern hemisphere as well. 
SummerTimeMode implemented in ComAp controllers is based on CET summer time which means:  
  Clock goes forward 1 hour at 2:00 a.m. on the last Sunday in March  
  Clock goes backwards 1 hour at 3:00 a.m. on the last Sunday in Octorber  
NOTE: 
Please be aware that in other regions summer time adjustments may be done in different time.
