CAN and CANopen
Standardized device parameter access
The neMESYS syringe pumps are connected via the CAN bus and use the CANopen protocol for standardized access to all device parameters. If your PLC has a CAN interface, you can connect it directly to the pumps using an appropriate adapter cable.
If your PLC has no CAN interface, you can also access the pumps via RS232 interface. Each neMESYS pump has an RS232-CAN gateway. You only connect your PLC to the first pump via RS232 and then have immediate access to all other pumps on the internal neMESYS CAN bus.
With the appropriate adapter cable you simply connect your CETONI devices to the CAN bus or RS232 interface of your controller. The 24V for the power supply of the CETONI devices can be connected via the two cable strands.
