Electronic coupler 600-151-1AA11

I/OPROFIBUS-DP bus

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. 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) 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) 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
