Soft starter monitoring I/O data structure

Master > Slave output byte is structured as follows:
Table 5-3 Monitoring I/O data structure
Operating data request (Data request numbers 1 to 14)
Slave > Master input bytes, in response to an operating data request, are structured as follows:
Echo data request number
Bits 7 to 1 Reserved
Data value - high byte
Data value - low byte
An invalid data request number will result in the Invalid data request number bit being set = 1.
NOTE
Data values are defined as follows:
Table 5-4 Data values

1 Soft starter product type code:
4 = Digistart CS
8 = Digistart IS

Voltage data is only available from the Digistart IS if the voltage measuring card is installed.
Data request numbers 5 to 14 are only valid for Digistart IS starters. Digistart CS starters will return zero values.
NOTE
Input bytes for data request numbers 6 and 7 are defined as follows:
Bit 7
High Byte
Low Byte
Powerscale functions as follows:
0 = multiply Power by 10 to get W
1 = multiply Power by 100 to get W
2 = Power is represented in kW
3 = multiply Power by 10 to get kW
