4.1 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.
l Up to 32 modules can be connected to a CAN gateway
l Integrated power supply unit for the internal voltage supply and the voltage
supply of the connected electronic modules
Power supply unit is fed via an external DC voltage source
l Connection to the system bus (CAN) / CANopen via a 9−pole Sub−D plug
l Address and baud rate setting via coding switch
l The baud rate is stored permanently in an EEPROM in the module
l LED for status display
