Function Codes
Function Code Function
03 Read holding registers
06 Write single register
08 Diagnostics (Sub-function 00 – Return query data)
16 Write multiple registers
17 Report slave ID – Returns manufacturer, model name, and serial number (standard Veris format)
All of these values correspond to BACnet objects with the same name. See the BACnet Conformance Statement for
their definitions.
Note that an attempt to write to “read only” holding registers will give an error and the entire write command will
not be executed even if writing to read/write locations were also requested. Exception code 2 is given in this case.
“Preserved” means the values is maintained through power outages.
