TB20-C, Bus Coupler MODBUS TCP
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.
.
This bus coupler will make it possible to run a distributed I/O station with nothing more than an Ethernet cable.
Note:
The 24 V power supply connector, the final bus cover, and the base module are included as standard.
TB20 ToolBox makes it easy to methodically design TB20 systems. Integrated terminal mapping, system width calculations, and Current-carrying capacity monitoring all make it possible to quickly design systems without making any mistakes.
