KNX_Read_DPT_5x (FB)

FUNCTION_BLOCK KNX_Read_DPT_5x EXTENDS SlaveBasic

Overview

Read function for DPT 5.x (8-bit unsigned).

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 5.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

• tNextRequest (TIME): Time until next read operation

Usage

1. Select the DPT 5.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.
