16.2.8 Parameter Map
The Orbit ACS Modbus Parameter Map is Document “503116 Orbit ACS Modbus Parameter Map – SI100SI200 .pdf” , or “503166
Orbit ACS Modbus Parameter Map – SI400.pdf” , available on the Solartron Metrology Web Site.
The table at the bottom of the file shows descriptions for enumerated values.
16.2.9 ACS, Modbus Floating point
In order to provide 32 bit floating point type data for parameters, the ACS products provide a floating point interface to any parameter
by way of an address offset. This provides an alternate address to read over Modbus, providing a floating point representation of any
parameter.
To acquire an IEEE-754 floating point value for any parameter, add 8000 to the address of the parameter required and read 2, 16 bit
registers in a multiple register read command. The data returned will be a floating point number for the parameter at address
supplied -8000, i.e. Read address 8001 as a floating point will yield the floating point value for the parameter at address 1.
