3.5.6 CAN - DeviceNet port
DeviceNet is a CAN-based communication network in which components from many manufacturers can be instal-
led quickly and simply.
It is a handy solution for connecting low level peripherals in the network.
The structure lets you connect up to 64 devices (including masters) in a single network.

3.5.5 CAN - CANopen port
The optional CAN port lets terminal dialog via the serial standard (ISO 11898-1 of 2003) for the CAN (Controller
Area Network) field bus, also known as CAN-bus.
The GF_VEDO EL35CT implements the CANOpen Layer 2 standard.
The CAN port is optically isolated and uses a 9-pin (male) D-sub connector.
