Structure of the rho4.0
3.3 Operation with I/O-Gateway
PLC controls of different busses can be connected to each other with the
B~I/O gateway and the modular bus connections B~I/O M-DP or B~I/O
M-IBS and B~I/O M-CAN.
A rho4.0 can also change 8 or 20 bytes inputs and outputs per B~IO M
bus connection via other field busses (Profibus, Interbus S, CANopen).
The selection 8 or 20 bytes can be set at the switch S1 of the I/O gateway.
. The B~IO M-CAN groups can be only used from Firmware Version
1.3 for I/O-Gateway
