Sinamics Telegram

Hi guys

I am currently doing a Project with ET200sp CPU 1510 and Sinamics drive G120C PN. Everything in TIA portal. I want to use Standart Telegram1 PZD 2/2 but I have some questions:

1. That telegram does not include PKW Words and If I understand rigth I dont need them if I am not using any CP modules, PC/PG  and I have Everything conneted to Profinet. Am I right?

2. Which case actually I need to use PKW Words in telegram?

3. In case I will use Siemens telegram 353 PZD2/2, PKW4/4 and I have data area 1..12 byte should I use first 4byte as Control/status Words and rest 8 bytes for PKW?

Thanks

The PKW is a drive parameter read/write channel. It's a legacy of old times when async services on a Profibus DP hadn't existed yet.

It may be needed when using a Profibus-DP master or a ProfinetIO controller which does not support those services.

The PKW, AFAIK, goes first in the telegram. Find the functional charts in the engineering manual for your drive. All telegrams are shown there.

Thanks

May be somebody can help with Another question

I use Sinamics_telegram_library_V13_SP1_1 and noticed that bytes are swapped in telegram 1

Is it some fault or it is ok?

Hi again

I read some manuals and found that  SIMATIC use BIG-Endian and SINAMICS uses LITTLE-Endian

IS it right?
