Light function
Contents

1.Description

This module is used in conjunction with the DCS IP gateway (Gira Article No. 2620xx). Light calls of the door communication system can be evaluated and functions in the HS/FS or KNX/EIB can be run.

With the optional assignment of the Inputs 2 to 3, the arriving telegrams can be filtered with regard to the sending bus address and the sender type.

This means that: With the input set, only telegrams are evaluated which match the filter properties.
Example:
With the bus address "0xABCDEF" set, only telegrams are evaluated which have been sent from the bus address "0xABCDEF".
Note
If no filters are set, then all telegrams from TC bus light functions are evaluated!
Determination of the optional filter parameters
Two different methods are available for determining the filter parameters:
  1. Use of the HomeServer cheat sheet in the DCS IP gateway.
  2. Use of the logic node Display basic parameters in the "Door communication\Additional nodes" folder.
After the parameters are known, it is recommended that the inputs be assigned either group addresses or fixed values.

2.Inputs

No.NameInitialisationDescription
1Door communication Receive""
(14 bytes – Text)
Here the internal communication object Door communication Receive is assigned by the DCS IP gateway.
2Bus address""
(14 bytes – Text)

Optional specification of a bus address to which filtering should be applied.
The bus address must have the following format:
Example: 0xABCD07 or 0x42A305
Note
If this input remains free, the telegrams of random bus addresses are evaluated.
If a communication object is assigned but is not written to or provided with an initialisation value, then the object is considered not to be set. This means the incoming telegrams of all bus addresses are evaluated.
3Sender type0
Optional specification of a sender type to which filtering should be applied.
The following parameters are possible:
160 = Door station
161 = Living area intercom
162 = Living area intercom receiver
163 = Bus control device
164 = Switching actuator
165 = TC gateway
166 = Additional gong/Bus chiming mechanism
167 = Button interface
168 = DCS IP gateway
4Release1
This input enables the module to be blocked with regard to the telegram evaluation (e.g. for a time-controlled light function).

Input value is not equal to 0
The module is completely calculated. Output 1 is calculated depending on the default values. Output 2 sends no telegram!

Input value = 0
The module is not completely calculated. Output 2 is calculated depending on the default values. Output 1 sends no telegram!

3.Outputs

No.NameInitialisationSBCDescription
1Trigger - Module active 0s
A 1 is sent on this output when the input telegram matches all filter properties. If filters are missing, then a 1 telegram will be sent each time the code command of a light telegram is received. For input telegrams which do not meet the filter criteria, the output sends a 0.
2Trigger - Module inactive 0s
In the case of a blocked module, the output sends a 1 when the input telegram complies with all filter properties. In the case of a blocked module, the output sends a 0 when the telegram does not comply with the filter properties.
3Bus address""s
(14 bytes – Text)

Output of the bus address in the format: 0xABEF07
4Sender type0s
Device type from which the TC bus telegram has been sent.

160 = Door station
161 = Living area intercom
162 = Living area intercom receiver
163 = Bus control device
164 = Switching actuator
165 = TC gateway
166 = Additional gong/Bus chiming mechanism
167 = Button interface
168 = DCS IP gateway
5Error output0s
The output can be routed to the outside as a diagnostic output if necessary or during start-up in order to obtain information about possible errors.
Values in the value range 0 to 4 are sent.
0 = An error has not occurred.
1 = The default values must be checked.
2 = The characters of the bus address must be checked.
3 = A telegram with a different structure has been received (e.g. a light call).
4 = The logic is blocked.
s = send, sbc = send by change
