5.2 CAN gateway
The CAN gateway is the interface between the process level and the master bus
system. The control signals at the process level are transmitted by the electronic
modules. These modules are connected with the CAN gateway via the backplane
bus (EPM-T9XX). CAN gateway and the connected electronic modules
communicate via the backplane bus. A configuration is not required.
