OB3x cyclic time of diff. CPU s7-1500 series. Lower bound.

Unreality

Try to measure on a real PLC - each organization block individually.

Then, all at once - by successive measurements.

Helped than he could, as they say)))

 that's clear! I'm doing that on real hardware.

I've put all blocks according to manual in OB1 and OB30.

Only thing I don't understand and TIA portal struggles on it also, that two FB can't work with the same instance DB. Look at the attachment.

The thing you suggested doesn't comply the manual. So... what assurance is that it will issue plausible results. We didn't follow the manual once at the beginning. Holy smoke!

Look at the attachment.

Also, please don't provide any Siemens quotes from manuals.

• I have got them too.

Frankly saying, I have it too...

From programming rules point of view there's nothing wrong in it.

Hello,

However - you can use multiple FB block calls - multi instance FB/DB

As for the manual - everything is simple - try what you need.

There may be errors in this example, it is not ideal.

You can so report it to Siemens to make it better - this will be the best help from you)

Profiling... I have gotten it working.If it may call so.

However, this stuff was never evaluating even similar results.

I mean that each time when I push button 'refresh' it shows different [snip].

That's all.

Hello,

Different results are just what we need.
