TB20-C, bus coupler, 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.

    DETAILED DESCRIPTION

    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
