Hi Experts,
I'm new to Siemens world. At the present time I'm programming a drive in TIA Portal.
My setup is: Inverter G120 + CU 250S-2 + S7-1500.
I'm at 90% of the job but I still need to improve some things. For that I need to read some bits of of the telegram that is sent from/to the CU.
I programmed the system with Telegram 111 (now switched to free telegram to have more control on the drive but the basic mapping is the same), so the structure is this:
The CU communicates to the PLC through:
I tried to read the bits from I6.0 to I7.7 to see the third word but the result doesn't match with the word that I can read from the startdrive (It should be the same, shouldn't it?):
So I am doing something wrong.
What sould I do to read the bits in the last picture?
Thanks
