Sutraction of FW and DW

hello guys,

Yours help is required more than ever before , I have step into complete confusion due to one of the  elements in the program exactly with subtraction in my PB33 I have got in the program simple subtraction FW and DW but the whole problem is that this value is different in status variables and different at the destination block  

T FW 108

L DW 35

-F

T FW 106

JU PB65

don't know why but cant attached more pictures so I explain:

in status variables value of these are as below

FW 108               KF+ 20

DW 35                 KF+731

FW 106                KF+10      ?????

but at the destination in PB65 this value equals to -1 ?????          

  Everything is happening in within DB4

Please see the attached picture , thanks for any hints and explanation in advance .

Regards

Konrad

The Step 5 Status will be updatet at end of OB1 scan.

I am quite shure that FW106 will be written also on an other position as that one that yo are watching.

So, the first result is overwritten at some other Position (direct or perhaps indirect).

Hello,

Status variable must be not at the point in your PB. Maybe the FW is written more times. Please show a screenshot from the PB with "status block".

Hello Gents,

thank you for your fast reply

to/Andre I do have picture that represents this value in block PB 65 I am attaching it.

this picture was taken at the same time when other values were measured .

to/IBN-Service at the end of this network there is unconditional jump to PB 65 so how could this value be change. 

 Kind Regards

Konrad

Hello,

i only need the values before you jump to the PB. Screenshot like the last..

Andre,

I just have figure out that the reason for my problems is DW 109

and everything else is fine , merely I was looking for a value of 10

at PB 65 but have realized where the issue is after checking values that you

have requested .thank you for your help.

I am attaching picture.
