The RCNA-01 ControlNet Adapter module
The RCNA-01 ControlNet Adapter module can not originate
connections on its own, but a scanner node can open a
connection towards it. The ControlNet protocol is implemented
according to the ControlNet international specification for a
Communication adapter (profile number 12).
Through the RCNA-01 ControlNet Adapter module it is possible
to:
• give control commands to the drive
(Start, Stop, Run enable, etc.)
• feed a motor speed or torque reference to the drive
• give a process actual value or a process reference to the
PID controller of the drive
• read status information and actual values from the drive
• read and write drive parameter values
• reset a drive fault.
A connection to the RCNA-01 ControlNet Adapter can be opened
from a ControlNet scanner. The size of the connection can be up
to 450 bytes in each direction.
MacID (Node address) is selected by two decimal rotary switches.
The range is 1 to 99.
Bus length: 250 m (coax) with 48 nodes
