TB20 bus coupler, PROFINET IO

TB20 bus coupler, PROFINET IO

The PROFINET bus coupler is designed to connect a PROFINET bus to TB20 peripheral modules. It can accommodate up to 63 modules of any kind connected in series with the bus coupler. The bus coupler supports hot-swapping 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.
A functioning TB20 configuration will always require a bus coupler and at least one peripheral module.

  • 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 system's operation (I/O check)
  • Concealed "factory reset" switch for restoring the module to its factory settings
  • I/O device as per PROFINET IO (IEC 61158-6-10)
  • Up to 63 peripheral modules
  • Conformance Class C
  • Media Redundancy Protocol (MRP)
  • Automatic addressing / hot-swapping (LLDP, DCP)
  • Topology detection
