A Modbus <b>request</b> is way of obtaining data from Modbus slaves. The master a sends a request to a slave specifying which Modbus registers should be read. The slave then sends the requested data back to the Modbus master.

A Modbus <b>request</b> is way of obtaining data from Modbus slaves. The master a sends a request to a slave specifying which Modbus registers should be read. The slave then sends the requested data back to the Modbus master. You can create a maximum of 64 request configurations for each slave device.
