TB20 Bus coupler, PROFIBUS-DP

Name: TB20 Bus coupler, PROFIBUS-DP
Brand: Helmholz
SKU: 600-151-1AA11
Availability: InStock

The PROFIBUS-DP bus coupler is designed to connect a PROFIBUS bus to TB20 peripheral modules. It supports the DP-V0 and DP-V1 protocols.
It will recognize all connected peripheral modules and assign each module the corresponding inputs/outputs from the process image table.
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-swap for replacing modules during operation.

Bit packing:
Starting with firmware version 1.20, the states of 2-bit and?4-bit I/O modules can be packed together in bytes, making it possible to take full advantage of all the space in the process image table.
