TB20-C, bus coupler
CANopen Slave
CANopen Slave
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.
- Modules can be replaced during operation (hot-swapping)
- 24 V DC power supply
- Integrated power supply unit for powering peripheral modules (2.5 A)
- Supplies the system’s I/O voltage (24 VDC)
- USB device port for online diagnostics, configuring parameters, setup, and firmware updates with "TB20 ToolBox"
- TB20 ToolBox simulation for commissioning the I/O system without a higher-level controller in order to test the functionality (I/O check)
- Concealed "factory reset" switch for restoring the module to its factory settings
- CANopen protocol as defined in DSP301 and DS401
- Transfer rates of 50 kbps to 1 Mbps
- 24 TPDOs / 24 RPDOs
- 1 SDO server
- Heartbeat producer
- Two heartbeat consumers
- Node guarding
- SYNC object
- Storable parameter configuration
- Up to 64 peripheral modules
