TB20 starter kit, PROFIBUS-DPThe 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.ParametersDiagnostic alarm: On | OffProcess alarm: On | OffPull/plug alarm: On | OffStartup when expected/actual configuration differ:  On | Off  (hot-swaping allowed: Yes | No)Identifier-related diagnostics: On | OffSubmodule status: On | OffChannel-related diagnostics: On | OffModules can be replaced during operation (hot-swapping)24 VDC power supplyIntegrated 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 ToolBoxTB20 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 61158Supports all PROFIBUS baud ratesDP-V0 and DP-V1 supportUp to 64 peripheral modulesUp to 244 bytes of input data and 244 bytes of output dataOne class 1 master connection with 240 bytes of payload dataUp to three class 2 master connections with 240 bytes of payload data (as a DP-V1 slave)I&M data3 LEDs, one of them bi-colorConcealed “factory reset” switch for restoring the module to its factory settings
