For each parameter there are four registers associated; the first two contain the value of the parameter in float data type, and the last two are the value scaled by 100 in Int16 format, and the status of the parameter in Uint16.
The table uses PDU addressing; addresses start at zero. Depending on the PLC used it might be required to add 1 to the addresses in the table below.
