moving M0.0 to Db0:0.0

ni lar

Hello,

Thanks for yours attension to my question.

I want to see all alarms history from HMI alarm history page.
In PLC program , I used M1.0, M1.1 , M1.2...for the error bits trigger from PLC.
But in HMI software , there is no M bits for Memory Desigination in PLC .
DB, IW,QW,MW,T,C only have.
So I do not know how to solve this problem.

So please advise me.

Thanks.

Best Regards,
Ni Lar

Hello

Here is one solution in Stl source

DATA_BLOCK DB 4
TITLE =
VERSION : 0.1

STRUCT
DB_VAR : INT ;//Temporary placeholder variable
alarm1 : BOOL ;
alarm2 : BOOL ;
alarm3 : BOOL ;
alarm4 : BOOL ;
alarm5 : BOOL ;
alarm6 : BOOL ;
alarm7 : BOOL ;
alarm8 : BOOL ;
END_STRUCT ;
BEGIN
DB_VAR := 0;
alarm1 := FALSE;
alarm2 := FALSE;
alarm3 := FALSE;
alarm4 := FALSE;
alarm5 := FALSE;
alarm6 := FALSE;
alarm7 := FALSE;
alarm8 := FALSE;
END_DATA_BLOCK

FUNCTION FC 10 : VOID
TITLE =
VERSION : 0.1

BEGIN
NETWORK
TITLE =Bit by bit

A M 0.0;
= DB4.DBX 2.0;
NETWORK
TITLE =8 bit at once

L MB 0;
T DB4.DBB 2;
NOP 0;
END_FUNCTION

Attached, code in FBD
