TB20-C ProfiNet Slave head for TB20 I/O system Includes internal Power module Up to 64 modules per rack (Siemens ET200S only allows 12) Hotswap module capable Free Software Toolbox for simulation and diagnosis in addition to information available from Siemens STEP7 / TIA Portal, or WinPLC7 software. Detailed status indication of all modules in use in the system Fault Tracking and fault repair Galvanic isolation between fieldbus and backplane bus TB20-C, Bus Coupler PROFINET IO The PROFINET bus coupler is designed to connect a PROFINET bus to TB20 peripheral modules. A functioning TB20 configuration will always require a bus coupler and at least one peripheral module, but can accommodate up to 63 modules of any kind connected in series with the bus coupler. The bus coupler supports hot-plug for replacing modules during operation. In addition, it will recognize all connected peripheral modules and assign each module the corresponding inputs/outputs from the process image table. PROFINET bus coupler with Power over Ethernet (PoE): A PROFINET bus coupler version featuring Power over Ethernet (PoE) will soon be available as well. This bus coupler will make it possible to run a distributed I/O station with nothing more than an Ethernet cable. Note: The 24 V power supply connector, the final bus cover, and the base module are included as standard. TB20 ToolBox makes it easy to methodically design TB20 systems. Integrated terminal mapping, system width calculations, and Current-carrying capacity monitoring all make it possible to quickly design systems without making any mistakes.
