  • Communication protocol: Honeywell Excel C-Bus
  • Station The station address is the C-Bus Id of the device in the range of 1 to 30.
  • You can execute an automatic synchronization of the real-time clock of EXCEL stations according to the time of the workstation. You must enable the synchronization and set the "Synchronization period" of real-time on tab the "Time parameters" tab in the configuration dialog box for the station. The recommended period is 3 to 12 hours. First The first synchronization is done when starting the D2000 KOM process.


Station protocol parameters

They influence a the behavior of access to the communication medium. You can define the following parameters:

Table 1

Key wordKeywordFull nameMeaningUnitDefault value
WREXPWrite Request Expiration TimeoutParameter The parameter defines a lifetime of request for writing a new value to the I/O tag. If this entry writing can not be done performed (e.g. because the communication with the station does not work), the request is cancelled canceled after elapsing this time elapses. An error message is written into the line trace file.sec60
IPTInit Point Response TimeoutTimeout until which the device must respond after sending the request for initialization of communication with I/O tag into the device. After elapsing this time elapses, an error message is written into the line trace file.sec6
WPTWrite Point Response TimeoutTimeout until which the device must respond after sending the request for writing the new value of I/O tag into the device. After elapsing this time elapses, an error message is written into the line trace file.sec4
PRPParameter Read PeriodePeriodRead The reading period of parameters from EXCEL devices. The changes in parameters (e.g. through EXCEL keyboard) are not transmitted automatically but they are read according to this period.sec600

Example:

IPT=10;WREXP=90;

If a key word keyword with a valid value has not been found in the initial string, the default value is used according to Table 1.

I/O tags: Ai, Ao, Di, Do, Co, TxtI, TxtO

    • I/O tag address is the name of the I/O object that is defined in the EXCEL device. It is a string of max. length of 18 characters. The address can contain also the attributes.
    • Reading and writing of values of EXCEL devices is are done by I/O tags with the following addresses:

$.Px-y

where x is a file number (0 to 127) and y is a parameter number (1 to 255) within a file. Example: $.P0-1 or $.P2-3

The reading/writing into time channels is done by I/O tags with these addresses:

AddressI/O tagMeaning
$.TPRFSHDoutBy writing the value FALSE into this I/O tag, the reading of all information about time programs is started. The reading is finished when the I/O tag acquires TRUE value.
$.TPLxTxtII/O tag acquires the name of the time program with index x (the index of the first time program is 1). If this time program does not exist, the I/O tag has will have an invalid value.
$.TPWSx-yTxtIName of the weekly schedule for time program with index x and day y (y in the range of 1 to 7 for Monday to Sunday).
$.TPDSx-yTxtIName of daily schedule with index y for time program with index x. If a daily schedule with this index does not exist, the I/O tag has tag will have an invalid value.
$.TPPLx-yTxtIName of the permitted object for control with index y in time program with index x. If an object with this index does not exist, the I/O tag has will have an invalid value.
$.TPADSPx-y-zTxtIName of an object in an action with index z, daily schedule with index y, time program with index x. If this action does not exist, the I/O tag has tag will have an invalid value.
$.TPADSTx-y-zTxtIExecution The execution time of action with index z, daily schedule with index y, time program with index x. If this action does not exist, the I/O tag has will have an invalid value.
$.TPADSVx-y-zTxtIValue The value assigned to object in the action with index z, daily schedule with index y, time program with index x. If this action does not exist, the I/O tag has will have an invalid value.
$.TPWWSx-yCoRecord of the new daily schedule in the weekly schedule. Day The day with index y (y in the range of 1 to 7 for Monday to Sunday), time program with index x. Recorded Written value is the index of dail daily schedule which was obtained by reading with the help of address $.TPDS addresses.
$.TPWDSx-yTxtOWriting/cancellation deletion of daily schedule with index y in time program x. The values:

"DEL" - cancels a daily program
"NEW;Name" - creates a new daily program with name "Name", the value of index y is ignored

$.TPADSWx-y-zTxtOWriting/change/cancellation deletion of action with index z in daily schedule with index y, time program with index x. The values:

"DEL" - cancels the action.
"NEW;HH:MM;ObjIndex;Value" - creates the action with time HH:MM, ObjIndex is the controlled object - i.e. index from a list which is obtained by $.TPPL address, and value Value. Index The index of action z is ignored.
"SET;HH:MM;Value" - changes the existing action over to the new time HH:MM or Value.


Note to the reading and controlling of the time programs:

To obtain the complex information about time programs by the static measurements I/O tags is virtually impossible because of their large quantity. Therefore there is enabled a dynamic change of address to read and write for all I/O tags for reading/writing of the time programs is enabled by Tell command SETPTADDR in all I/O tags SETPTADDR tell command. In combination of the with active pictures, you can implement a full displaying and controlling of the time programs. We created a sample solution as a template of for the D2000 configuration database.

...

AddressI/O tagMeaning
$.ALARMTxtIText variable that contains the last received alarm from the device (parent of I/O tag – station).
$.LISTTxtIText variable that contains the list of objects received from the device (parent of I/O tag – station).
$.CNAMETxtIText variable that contains the device name (Controller name).

...

You can obtain or modify the status M/A when you configure I/O tags Di, Dout with the address which contains the attribute - string ".MAN" string . True means that the object is in Manual status, False - the object is in Auto status. The both Both I/O tags must be defined so that this object could work properly. E.g. I/O tag with address "TeplTemp_vin_MiestnostiRoom_01" and another one with address "TeplTemp_vin_MiestnostiRoom_01.MAN". The change of I/O tag with the ".MAN" attribute means the change of the Manual/Auto status of object in the device.

...

Manual/Auto status can be gotten read or modified also by the setting of the A flag in object value. The object with ".MAN" attribute is not necessary then. If A flag is set, the object is in Auto status. If it is not set, the object is in Manual status.
