KNX_Read_DPT_6x

KNX_Read_DPT_6x (FB)

FUNCTION_BLOCK KNX_Read_DPT_6x EXTENDS SlaveBasic

Overview

Read function for DPT 6.x (8-bit signed).

Inputs

Inputs	Initial value	Description
xRequest	FALSE	Trigger for single read
xRequestVisu	FALSE	Trigger for single read (visualization)
tRequestTime	T#0S	Interval for cyclic reading
eDPT_Format	-	DPT 6.x format selection
byAdrGroup	0	Group address (0-255)
byAdrMiddleGroup	0	Middle group address (0-7)
byAdrMainGroup	0	Main group address (0-31)
iInitValue	0	Initial value at InitOption.InitValue
eInitOption	-	Initialization option

Outputs

• iValue (INT): Received integer value

• sUnit (STRING[10]): Unit of the value

• xStatus_A to xStatus_E (BOOL): Status bits (only for DPT 6.020)

• xMode_0 to xMode_2 (BOOL): Mode bits (only for DPT 6.020)

• tNextRequest (TIME): Time until next read operation

Usage

1. Select the DPT 6.x format with eDPT_Format.

2. Configure the read options as with the previous blocks.

3. Monitor iValue for received values and sUnit for the unit.

4. For DPT 6.020: Note the additional status and mode bits.
