Hello:
I'll read out Module Information by SFC51, and there are nine items in the Module Information (General、Diagnostic Buffer、Memory、Performance Data、Identification....).
May I ask one qustion aboutWhich numberto choose SSL ID number to read out that information ,following
1.Time system
2.Scan Cycle Time
3.Stacks
4.Communication
I really need to know SSL ID number then to try again

Best regards !

Hello:
Excuse me , About my question is Ctrl+D (Module Information),It have nine items.Use SFC51
I read out General(SSL -IDxy11)、Diagnostic Buffer(SSL-IDxyA0)、Memery(SSL-IDxy13)、Performance Data(SSL-IDxy14,15)、Identification(SSL-IDxy11),

If focus on SFC51,How Can I read out the other ?
Time system----------------SSL-ID?
Scan cycle Time----------SSL-ID?
Stack--------------------------SSL-ID?
Communication------------SSL-ID?

Ok, now i got what you want. These data is read not through SFC51. Now
Time system - hascurrenttime,whichcanbereadoutwithSFC1.
has info on runtimemeters - which can be read out with SFC4/SFC101
Syncronization info - i think you can't read this one - it changes ONLY during HW reload

Scan cycle Time- contains last cycle time, shortest and longest
No SFCs required - just read OB1 temp variables corresponding times in ms)
OB1_PREV_CYCLE
OB1_MIN_CYCLE
OB1_MAX_CYCLE

Stacks- contains LOTS of diagnostic info - but only in STOP/ HOLD mode. In this modes programm inside PLC is not running - so you won't get any info even if you could - PLC is just not running.
Ok, supose you could read stacks - what would you get?
I stack contains registers contents - AR1/2,Db,DI,ACCU1-4,statusword.
Youcangetthisinfousingordinarycommands.
L Stack contains local data stack.Simplyuseload for local data like LLW21.
Bstack - don't know exacly

Communication- hm, here i'm unsure.
Transmission rate is changed with entire HW - whatfor do you need it in programm? Number of occupied communication resources may beinteresting,butican'trememberifthat'sinfoisavaible.
Guessnot

Hello:
I can read out "Time system" "Scan cycle max and min time" from OB1.
I also knew abut stackcan't read outthat reason is stop mode

and communication can't read out from CPU that reason is constant information unsupported.

Thanks for your kindness .

But now about "communication", I can't find in the HW Config.
The CPU order number is 6ES7 414-3XJ04-0AB0, It's so strange.
Couldyou please tell meabout that information?

Bestregards !
