How to represent all of these digits in one word ?

Hi

it is best to write comms block as an FC and you can have one for ABB drive

and re-create it for Parker which have different process image.

in general, status and control word may be different as well.

Scaling for command may be different too.

Hello «Crocodiel;

As Piotr has stated, there is very little chance that an ABB drive command structure will work with your SSD 590+ drive. ABB follows Profidrive, so the number and order of registers in a telegram will be the same as for a Micromaster drive for example, even though the order and selection of bits in the Control Word would not match the ones in a Siemens drive. But the SSD drive follows a very different command structure.

It seems that in the Parker SSD family all you can do from Profibus is to read or write parameters, with specific values. I seem to recall pointing out parameter 212 (JOG) with a value of 4 as a Run command, in one of my earlier posts.The same document that parameter list was taken from used specific command formats to read/write the parameters to the drive.

Now, have a look at one more documents from Parker's website:

http://www.parker.com/Literature/Electromechanical%20North%20America/App%20Notes/Technical%20App%20Notes%20for%20Communications.pdf

Look at Document 7703 :  To setup communications between a Siemens PLC S7-315 Master to SSD Drives Profibus communication module L5353.

It gives a step by step configuration of a SSD drive as a slave  for Profibus communications. Once you have set it up properly, contact Parker support directly and ask for details on the exchange structure, how to start/stop the drive, how to give it and change a speed setpoint, and how to read process values from the drive. That would be the best source at this point.

Hope this helps,
