From firmware version 4.0.0, the Asycube offers a Modbus TCP slave (=server) interface in order to simplify the integration with PLCs and other Modbus TCP masters (=clients) over TCP/IP networks. More information on Modbus can be found in the protocol specification available on http://www.modbus.org.
This documentation is separated in multiple sections:
Configuration presents all necessary information to communicate with the Asycube through Modbus TCP.
Performance shows typical performances that can be achieved.
Asycube Modbus Register Table list all the registers that can be read or wrote.
Errors explains the different types of errors and the way to handle them.
Example of use gives a few useful examples, such as how to start a platform vibration through Modbus TCP.
