he EtherCAT bus coupler makes it possible to access data from peripheral modules using the EtherCAT protocol.
It can accommodate up to 64 modules of any kind connected in series with the bus coupler.
It detects peripheral modules that are plugged in and can assign the corresponding I/O data to an EtherCAT mapping automatically.
The EtherCAT bus coupler supports the Modular Device Profile.
A large I/O image table size of 1,024 bytes makes it possible toimplement 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.
Alternatively, the configuration can also be edited using the CoE object dictionary.
Finally, running TB20 systems can be diagnosed in real-time and set up for testing purposes if an EtherCAT master is not yet connected (simulation / I/O check).
A functioning TB20 configuration will always require a bus coupler and at least one peripheral module.
- EtherCAT slave with Modular Device Profile (MDP) support
- Two EtherCAT ports (RJ45, 100BASE-TX)
- Up to 64 peripheral modules
- Modules can be replaced during operation (hot-swap)
- Automatic module I/O data mapping
- 1024 bytes of input data; 1024 bytes of output data
- 24 V DC power supply
- Integrated power supply unit for powering peripheral modules (2.5 A)
- Supplies the system’s I/O voltage (24 V DC)
- 5 LEDs used as indicators for the current coupler, EtherCAT, and the link/activity status
- USB device port for online diagnostics, configuring parameters, setup, and firmware updates with “TB20 ToolBox”
- Can be alternatively configured, including its parameters, using the CoE protocol
- 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)
- Concealed “factory reset” switch for restoring the module to its factory settings
