4.2 CAN GatewayECO
The CAN GatewayECO 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 8 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 Only supports the electronic module types EPM−T2xx and EPM−T3xx
l Connection to the system bus (CAN) / CANopen via a 9−pole Sub−D plug
l Address and baud rate setting via DIP switch
l The baud rate is stored permanently in an EEPROM in the module
l LED for status display
