Page 29: Setup And Wiring
4 Setup and wiring 4.1 EMC/safety/shielding The TB20 IO system complies with EU Directive 2004/108/EC (“Electromagnetic Compatibility”). One effective way to protect against disturbances caused by electromagnetic interference is to shield electric cables, wires, and components. When setting up the system and laying the necessary cables, make sure to fully comply with all standards, regulations, and rules regarding shielding (please also consult the relevant guidelines and documents published by the PROFIBUS User Organization). -
Page 30: Front Connectors
It is also possible, for example, to connect two 0.75 mm² wires to a single spring-type terminal, provided the maximum cross-sectional cable area of 1.5 mm² per terminal is not exceeded. The cables can be attached to the underside of the front connector with a cable tie. TB20 DeviceNet Coupler | Version 2 | 2017-05-29... -
Page 31: Wiring The Coupler
The coupler and the modules are grounded via the shield contact to the DIN rail. The DIN rail must be grounded. The surface of the DIN rail must be clean and conduct electricity well. TB20 DeviceNet Coupler | Version 2 | 2017-05-29... -

• Integrated power supply unit for powering peripheral modules (2.5 A) • Supplies the system’s I/O voltage (24 VDC) • Six LEDs, four of them bi-color (three DeviceNet LEDs and one TB20 specific) • USB device port for online diagnostics, configuring parameters, setup, and firmware updates with "TB20-ToolBox"... -
Page 37: Configuration And Use
The DeviceNet™ coupler uses an “Open Style” connector to connect to the DeviceNet™ network. Since the coupler uses its internal 24 VDC for network power, connecting 24 VDC to pin 1 (V+) is used only for network power detection failure.

Page 42: Simulation Mode
To ensure that this does not lead to accidents or malfunctions in the physical system and the higher-level controllers, the TB20 terminal will remove itself from the bus system and TB20-ToolBox will show a message to this effect once the simulation starts. -
Page 43: Firmware Updates
The latest firmware files will be automatically installed after setting up TB20-ToolBox and will be available so that the TB20 coupler's operating system can be updated through a USB connection. The TB20-ToolBox program can be downloaded at any time from the Downloads area at www.helmholz.de. - Page 44 A progress bar will indicate the transfer's progress. Once the update is successfully completed, the active firmware version will be shown in the Info pane in online mode. TB20 DeviceNet Coupler | Version 2 | 2017-05-29...

The three following events will all trigger a DeviceNet™ coupler (re)start: 1. Power on 2. "Reset" command from the DeviceNet™ bus (on the Identity object instance 1) or TB20-ToolBox 3. A physical change to the module setup There are two different possible startup flows for the DeviceNet™ coupler: Startup flow 1: A project is already stored in the coupler's non-volatile memory. - Page 46 If there are no gaps, the modules will be switched to STOP and then start running (RUN) with their standard configuration. Once this is done, the coupler will carry out its mapping routine based on the modules that are plugged in. TB20 DeviceNet Coupler | Version 2 | 2017-05-29...
