TB20 bus coupler
EtherNet / IP
A functioning TB20 configuration will always require a bus coupler and at least one peripheral module.
Note: Individual modules cannot be combined with the IO systems of other manufacturers.
The EtherNet/IP bus coupler makes it possible to access data from peripheral modules using the EtherNet/IP protocol. It can accommodate up to 64 modules of any kind connected in series with the bus coupler.
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.
A functioning TB20 configuration will always require a bus coupler and at least one peripheral module. The bus coupler supports hot-swapping for replacing modules during operation.
Note: Individual modules cannot be combined with the IO systems of other manufacturers.
- Modules can be replaced during operation (hot-swapping)
- 24 V DC power supply
- Integrated power supply unit for powering peripheral modules (2.5 A)

- 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 functionality (I/O check)
- Concealed "factory reset" switch for restoring the module to its factory settings
- 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 memory image within the assemblies
