TB20, Bus Coupler

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.

TB20-C, Bus Coupler EtherNet/IP 

The EtherNet/IP bus coupler makes it possible to access data from peripheral modules using the EtherNet/IP protocol. 
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-plug for replacing modules during operation.
It detects peripheral modules that are plugged in and allows access to the modules` I/O data via input/output assemblies.
The EtherNet/IP bus coupler features an integrated two-port switch that allows for star and line topology configurations. 
A large I/O image table size of one kbyte makes it possible to implement comprehensive and complex systems.
TB20 ToolBox can be used to easily configure the system and the various module parameters and transfer the corresponding settings to the coupler.

Characteristics
• Supports unicast and multicast CIP connections
• 511 bytes of input assembly data; 511 bytes of output assembly data
• TB20 ToolBox can be used for easy access to assembly sizes and to the structure of the image table within the 
  assemblies
• Up to 64 peripheral modules
• Modules can be replaced during operation (hot-plug)
• Implicit messaging (transport class 1)
• Explicit messaging (transport class 3)
• TCP watchdog
• IP address can be set relative to a base IP address by using a DIP switch that can be covered
• DHCP (can be selected using DIP switch)
• Integrated two-port switch with two RJ45 connectors
• Module process data is automatically assigned to the EtherNet/IP mapping
• 24 VDC power supply
• Integrated power supply unit for powering peripheral modules (2.5 A)
• Supplies the system’s I/O voltage (24 VDC)
• 9 LEDs, three of them bi-color
• USB device port for online diagnostics, configuring parameters, setup, and firmware updates with "TB20 ToolBox"
• 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)
