Telegrams adaptive

Hello,

in general you can receive only parameters that are named with "CO:..." or "BO:....". Those parameters are connectable BiCo parameters and can be assigned to a telegram word.

So at the drive side you set up a standard telegram (e.g. telegram 1). After that you can add supplementary data with a certain length to it or you change the standard telegram to "free BiCo" and extend the length of this telegram. In the new free words you can put the BiCo parameters to be transfered to the PLC.

At the PLC side I would recommend to create a DB with the structure of the telegram. With the system functions "GETIO" or "GETIO_PART" you can read the telegram data and store it in the DB. Please see the attached short PDF.

Note that STW1 should be always the same and the communication is only running if Bit 10 is send from the PLC to the drive.

Please also note that this is no official application description and is not described completely in detail. Also there are of course other methods available to program and set up the communication! This is just one idea.
