s7->tp177b

hello!!
my name is Michał,first I'd like to apologize for my no good english
I've problem with change time in my touch panel by runtime, I read time from driver cpu313c-2dp and put on my visualization and i don't know how change system time, because I use system alarm logging and this system take time and date from windows CE, Is there any solution to this problem. I need control (write and read ) time from my cpu.

I amn't sure did the TP177b support PLC jobs or not, but if yes, this is a solution. I tried to insert PLC job in WinCC flexible for this panel now but without success...

This is the function you want. It uses Job 40 to syncronise time.

It is on the second page.

This is the outline of the code

AN "SET_TIME" // Start Read Time Sequence
JC end
L 40 // jobnr 40
T DB20.DBB 109 // in jobmailbox
SET
S M 5.1
R "SET_TIME"
end: NOP 0
AN M 5.1
JC ende

L W#16#0 // job finished?
L "WORK_DB".JobMailBox
==I
= #enable

A M 5.1
A #enable
L S5T#1S
SP T 20
LC T 20
T MW 70
A T 20
= M 5.2

SET
A #enable
AN M 5.2
JCN ende
CALL "SET_CLK"
PDT :="WORK_DB".OP_TIME
RET_VAL:=MW75
SET
R M 5.1
ende: NOP 0
