KNX_Read_DPT_19x (FB)

FUNCTION_BLOCK KNX_Read_DPT_19x EXTENDS SlaveBasic

Overview

Read function for DPT 19.x (date and time).

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 19.x format selection
byAdrGroup	0	Group address (0-255)
byAdrMiddleGroup	0	Middle group address (0-7)
byAdrMainGroup	0	Main group address (0-31)
dtInitValue	-	Initial value (not effective)
eInitOption	-	Initialization option

Outputs

• wYear (WORD): year

• wMonth (WORD): month

• wDayOfMonth (WORD): day of the month

• wDayOfWeek (WORD): day of the week

• wHourOfDay (WORD): hour

• wMinutes (WORD): minutes

• wSeconds (WORD): seconds

• tNextRequest (TIME): Time until next read operation

Usage

1. Select the DPT 19.x format with eDPT_Format.

2. Configure the read options:

   • For cyclic reading: tRequestTime > T#0S

   • For event-based reading: use xRequest or xRequestVisu

3. Set eInitOption for initialization (note that dtInitValue is not effective).

4. Monitor the individual time components (wYear, wMonth, etc.) for received values.
