The HN800+VBX01B ABB Bus Expansion Controller is a device supplied by ABB for industrial control systems. Based on the search results, here are some key information about the VBX01B ABB Bus expansion controller:
Model: VBX01BA, this is one of the models of ABB control system accessories.
Brand: ABB, a well-known manufacturer of industrial automation and control systems.
Product size: the net depth/length of the product is 180 mm, the net height of the product is 80 mm, the net width of the product is 160 mm.
Description: HN800/CW800 bus expander, vertical column, attached to the bottom of the HN800 device column and with conformal coating.
Function: Bus extender is a customized RS485 bus agent, and the market common RS485 hub is different, it uses 4 physical serial port CPU, through the software to achieve data exchange between different serial ports.
Application scenario: In practical engineering, it is often encountered that multiple devices read and write a 485 port at the same time, such as multiple computers need to read the same electricity meter at the same time, or local PLC and remote computer need to collect CTU data at the same time. VBX01BA bus extender can automatically queue in order of access and feedback the result to the request port to solve the problem of port conflict caused by multiple devices accessing the same 485 port.
