CRC calculation
The check field allows the receiver to check the validity of the message. The check field value is the Cyclical
Redundancy Check (CRC) based on the polynomial x
16
+x
15
+x
2
+1. CRC is counted from all message bytes
preceding the check field.
Online CRC calculator: http://www.lammertbies.nl/comm/info/crc-calculation.html Use CRC-16 (Modbus)
Write LSB first.
For writing nominal power 100kW the CRC is calculated from this data: 01060BC00064
