TB20-C, Bus coupler PROFIBUS-DPPROFIBUS-DP ■ Modules can be replaced during operation (hot-swapping) ■ 24 VDC 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 setting up the I/O system without a higher-level controller in order to test the system's operation (I/O check) ■ PROFIBUS DP slave as defined in EN 50170/IEC 61158 ■ Supports all PROFIBUS baud rates ■ DP-V0 and DP-V1 support ■ Up to 64 peripheral modules ■ Up to 244 bytes of input data and 244 bytes of output data ■ One class 1 master connection with 240 bytes of payload data ■ Up to three class 2 master connections with 240 bytes of payload data (as a DP-V1 slave) ■ I&M data ■ 3 LEDs, one of them bi-color ■ Concealed "factory reset" switch for restoring the module to its factory settings The PROFIBUS-DP bus coupler is designed to connect a PROFIBUS bus to TB20 peripheral modules. It supports the DP-V0 and DP-V1 protocols. It will recognize all connected peripheral modules and assign each module the corresponding inputs/outputs from the process image table. A functioning TB20 configuration will always require a bus coupler and at least one peripheral module, but can accommodate up to 64 modules of any kind connected in series with the bus coupler. The bus coupler supports hot-swap for replacing modules during operation. Bit packing: Starting with firmware version 1.20, the states of 2-bit and 4-bit I/O modules can be packed together in bytes, making it possible to take full advantage of all the space in the process image table.
