8 Replacing the EMF2172IB communication module (CAN)
Observe the following information when replacing the EMF2172IB (CAN) communication
module by EMF2178IB (CANopen):
ƒ The communication modules feature different plug connectors for connecting the
voltage supply and the system bus (CAN).
ƒ The DIP switches of the communication modules feature different assignments for
setting the CAN node address and the baud rate ( ^ 75). Furthermore there are
different adjustable CAN address ranges:
Communication module CAN address range DIP switch
EMF2172IB (CAN) 1 ... 63 S4 ... S9
EMF2178IB (CANopen) 1 ... 127 S1 ... S7
ƒ Depending on the standard device used, the 2. SDO channel is activated via code
C1865/1 or C2365/1 ( ^ 76).
