TB20 bus coupler
CANopen
A functioning TB20 configuration will always require a bus coupler and at least one peripheral module.
Note: Individual modules cannot be combined with the IO systems of other manufacturers.
The CANopen bus coupler is designed to connect a CAN bus to TB20 peripheral modules.
It supports the CANopen protocol as defined in DS301 and uses the DSP-401 profile for digital and analog I/O modules.
Up to 64 modules of any kind can be connected in series with the bus coupler.
This coupler makes it possible to use SDOs to freely access all I/O values, parameters, and diagnostics, and can manage up to 192 bytes of I/O data with the PDO protocol.
A functioning TB20 configuration will always require a bus coupler and at least one peripheral module. The bus coupler supports hot-swapping for replacing modules during operation.
Note: Individual modules cannot be combined with the IO systems of other manufacturers.
