KNX_Read_DPT_2x

KNX_Read_DPT_2x (FB)

FUNCTION_BLOCK KNX_Read_DPT_2x EXTENDS SlaveBasic

Overview

Read function for DPT 2.x (1-bit controlled).

Inputs

Inputs	Initial value	Description
xRequest	FALSE	Trigger for one-time read
xRequestVisu	FALSE	Trigger for one-time read (visualization)
tRequestTime	T#0S	Interval for cyclic reading
eDPT_Format	-	DPT 2.x format selection
byAdrGroup	0	Group address (0-255)
byAdrMiddleGroup	0	Middle group address (0-7)
byAdrMainGroup	0	Main group address (0-31)
xInitValue	FALSE	Initial value at InitOption.InitValue
eInitOption	-	Initialization option

Outputs

• xValue (BOOL): Received Boolean value
• xControlBit (BOOL): Received control bit
• tNextRequest (TIME): Time until the next read operation

Usage

1. Select the DPT 2.x format with eDPT_Format.
2. Configure the read options as for DPT 1.x.
3. Monitor xValue for the main value and xControlBit for the control bit.
