TB20-C, Bus coupler
ModbusTCP
ModbusTCP
The ModbusTCP bus coupler makes it possible to access data from peripheral modules using the ModbusTCP protocol, but can accommodate up to 64 modules of any kind connected in series with the bus coupler.
The ModbusTCP bus coupler features an integrated two-port switch that allows for star and line topology configurations.
A large I/O image table size of 2 kbytes makes it possible to implement comprehensive and complex systems.
The control and status registers can be used to configure and monitor the coupler's behavior with ModbusTCP.
TB20 ToolBox can be used to easily configure the system structure 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)
- 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 functionality (I/O check)
- Concealed "factory reset" switch for restoring the module to its factory settings
- Connection watchdog for connection monitoring
- Simultaneous access to up to 10 stations (TCP connections)
- Integrated two-port switch
- Up to 64 peripheral modules
- 2 x RJ45 connections
- 2048 bytes of input, 2048 bytes of output data
- 126 bytes of parameter data per module
- The coupler's behavior can be configured using control registers
- The coupler's status can be read out using status registers
- 7 LEDs, one of them bi-color
