What is the maximum of exchanged data over Profibus DP on a PCD?
The maximum of exchanged data over a Profibus DP interface (or Profi-S-I/O) interface is depending on the system (the amount is not the same for a PCD7.F750 or a PCD3).
PCD7.F750 placed on a PCD2.M1x0 (non SBC-NT)
The Profibus DP manual states that the maximal amount of exchanged data per PCD7.F750 is 2942 bytes.
PCD3, PCD2.M5 or PCD2.M480 and PCD1.M2 (SBC-NT)
The limitation mentioned above does not apply for SBC-NT systems where the maximal amount of exchanged data is 2048 bytes.
