Devicenet / CM-DEV
communication
DeviceNet interface CM-DEV fulfils ODVA/CIP specification. It supports 2 types of
connection: explicit message and I/O message.
For I/O data exchange the following CIP defined output assemblies and input
assemblies for AC drives are available: output assemblies 20, 21, 22, 24, input
assemblies 70, 71, 72, 74.
In addition, the vendor specific output assembly 100 and input assembly 101 are
available.
CM-DEV is equipped with a 5-pole open style plug connector, designed in accordance
to ODVA standard.
CM-DEV benefits from the same design of other communication modules which allows
an easy plug and play mounting and connection to the drive.
Several very high transmission rates are supported, that are set according to the
transmission cable length.
Cable lenght Max Baud rate
up to 500m 125000
up to 250m 250000
up to 100m 500000
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.
