Hello!
I am using CPU 315-2 DP. Now i want to transfer the diagnostic buffer data to HMI device (touch screen panel),so that i can see the diagnostic buffer data on my touch screen.
If this operation is possible? If it is please somebody tell me how to do this.

Thanks for help,
Robi

Hi.
I would also do this, now I'm not need it. I'am stop in reading the manual and some test.
looks about the SFC 51 "RDSYSST" extraction lists.
Normaly I use SFC51 for read the Dp State and this way is good
good luck. bye

Thank you for answer.
Could you tell me some more information about using function SFC 51 "RDSYSST"?

Hi.
Start from link. There are some example but you must found the manual about SFC.
If in your S7 Manager put SFC51 after pres F1 and help online show up.

Forget. If you want know the value of scan time of plc write this code in OB1

L #OB1_MIN_CYCLE // LW6
T MW250

L #OB1_MAX_CYCLE // LW8
T MW252

L #OB1_PREV_CYCLE // LW10
T MW254

Value in mSec.
The register are in Temp of ob1
