Page 28: Multi-Host Mode
With the increase of the number of hosts, the Modbus timeout time should be increased accordingly. If multiple hosts are required to make continuous high-speed requests, it is recommended to use a "storage gateway", and it is recommended to configure "simple protocol conversion" when no multiple hosts are used.
