Description
The BODAS CAN I/O extension module RCE serves to provide
a simple and inexpensive extension of the I/O capacity exten-
sion of the RC controllers in the event that the number of
controller inputs and outputs is insufficient for the specified
application.
The RCE is connected to the RC controllers via the CAN bus.
The standardized CANopen protocol is used for communication
between the controller and extension module. The RCE is deliv-
ered with a standardized software package; no programming of
the RCE is, therefore, necessary. The RCE can be easily config-
ured with commercially available CANopen configuration tools.
This is performed via standardized CANopen routines by means
of so-called Service Data Objects (SDO).
