Hi.
I have a application where I have to print som Alarms to serial printer.
I have CP340 RS232 card beside my 315 CPU.

I have install software that comes with CP340.
I have configure in HW CP card, and I have all my massages stored there, in SDB file.

I have P_PRINT FB too, in OB1.

Today, in my application, all alarms are trigging a memmory bit.

How shall I do, so my memory bit is throu P_Print are picking upp right file from SDB file, and prnt it?

I have read some documents allready, but I could not fing what I was looking for.



I have been following this : Print - Get Started .. But get crazy , it doesnt work as I wish...
/tf/WW/en/postattachments/download?attachmentId=18725

How ever, I do I just get out message nr 1.

Now I have 5 different messages in SDB file, and they are downloaded .
I do trigg in VAT table M1.0 and print is starting. But I can only get out message 1.
In vat table I even have DB8.DBD 0. But it does not matter how much I change value for DB8.DBD0 - I still only get out message 1 ???
I tried to change DB_NO to 6, I tried to change DBB_NO to 2....Nothing happend.


In OB1 I have following:

CALL "READ_CLK"
RET_VAL:=MW3
CDT :=#Date_Time

CALL "DT_TOD"
IN :=#Date_Time
RET_VAL:="DB VAR 1".DB_VAR

NOP 0
CALL "P_PRINT" , "Inst.DB för FB4"
REQ :="M1.0"
R :=
LADDR :=272
DB_NO :=5
DBB_NO:=2
DONE :="M1.1"
ERROR :="M1.2"
STATUS:="MW2"





In SDB file I have following;

0 TestMessage 0
1TestMessage 1
2 TestMessage 2
3 TestMessage3
4 TestMessage 4
and
5 TestMessage 5

All DB 5 to 10 are made as inlinked example above. ( except that in DB9 , in example , Initail value should be writen as0(???) , andI have B#16#0.

Instans DB4 is same too.

Vat table same too.

And when I trigg in VAT M1.0, Message 0 is comming out.
But how to get out message 2, 3, 4 .... ????????
