CAN and CANopen (DS402)
Standardized device parameter access
CETONI devices are connected via the CAN bus and use the CANopen protocol for standardized access to all device parameters. Many PLC controllers, such as the devices from Beckhoff, B&R or WAGO, already have CANopen interfaces for direct connection of our devices or can be extended by CANopen capabilities via Bus Couplers.
The neMESYS Firmware Specification provides detailed information about access to the device parameters via CANopen and how to control the pump with your Beckhoff or WAGO PLC.
All our pumps have CAN and RS232 interfaces. The PLCs from Beckhoff, B&R or WAGO already have CANopen interfaces and can therefore be connected directly to the CAN interface of the neMESYS pumps.
With the appropriate adapter cable you simply connect your CETONI devices to the CAN bus of your controller. The 24V for the power supply of the CETONI devices can be connected via the two cable strands.
