connection between Drive and PLC using D2D connection!

Hello everyone
Is it possible to make a connection between AC500(PM554) PLC and ACS800 drive using D2D connection on ACS800?
What is needed for this!?

Hi

the use of the D2D is generally used for specific applications between drives, for example master follower.
What you ask can be done using the same terminals on the drive side, but by configuring the connection as ModBus RTU, and in the same way on your PM554.

To get an idea of how this connection can be made, you can use my app as a trace regarding the connection between a drive and a CP600 panel

Thank you Flavio
Yeah, you're right! I know that it's possible to make a connection between them using modbus RTU! as I found in related documents we need an additional module for this connection, FSCA01!! because of some reasons I don't want to use FSCA01!
Actually I wanna to find a way to make this connection without using FSCA01! Is it possible!? Do you have any hint on it!?

It's not necessary - IMHO - the use of FSCA module, try to read the manual very well regarding the parameters of group 58.

Thank you Flavio
so what is the necessity of using FSCA01!? I mean what is the advantage of it!?

HI
I read the acs880 firmware manual, automation builder help, and one another document of abb(since then i'll call it mentioned document)! I actually get confused!
based on information in "automation builder help" and the "mentioned document of abb" the connection between ACS880 and AC500(PM554-eth) could be happen just using FSCA-01 module on modbus rtu protocol! but coversely based on acs880 firmware manual it's possible to make this connection using "embedded fieldbus interface"(the 58 group)! this a serious contradiction that makes me confused!!
in link below I've attached some files to make it more clear!

Hi

In the same way that other ABB drives - and I refer, for example to ACS580 which is the "smaller" brother of ACS880 - can be connected in ModBus RTU with the terminals embedded on the drive, I believe that ACS880 is also connectable in the same way.
In reality, the FSCA-01 is used when for example the terminals on the drive are used for a D2D towards another drive (master-follower is a typical application with this connection method) and a further Modbus is needed towards, for example , a control PLC.
Therefore, as far as I can remember, you can safely use the terminals on the drive for your ModBus RTU
