DP / CM-PDP V1
Profibus Communication
Profibus DP interface fulfils fieldbus standard DIN 19245. This Profibus version, which
is optimized in order to provide excellent performance in terms of speed and low
connection costs, has been adapted for communication between automation systems
and decentralized peripheral devices.
Following “variable speed drive” profiles defined by Profidrive for electrical drive
technology are supported by CMP-DP: PPO1, PPO2, PPO3, PPO4.
CM-PDP interface supports different transmission rates in compliance with EN 50170
standard. The transmission rate automatically adjusts to the settings of the fieldbus
master.
CM-PDP module is equipped with a DIP switch to activate end-of-line terminating
resistor, included into CM-PDP.
Cable lenght Max Baud rate
up to 1200m 93.75
up to 1000m 187.5
up to 400m 500
up to 200m 1500
up to 100m 12000
Cable length limits the transmission
bandwith. Above table shows the match
between admissible cable lengths and
corresponding max kBaud rates. Values are
indicative and may significantly change
in relation to the transmission cable
characteristics.
