How to Select 5 or 6-Digit Registers
In Master or Snooper Mode, it is possible to select either a five-digit or a six-digit Register Number. Once
the operator has enabled a PV, entered a Slave ID, and chosen a Function Code, the scanner will arrive at the
Register Number menu (reg.nbr). Press the Right arrow to display and then the Up arrow to change the
setting for the number of digits used for the Register Number (5 dig or 6 dig), then press ENTER.
Notes:
1. If Function Code 03 is selected, the Register Number defaults to 40001; if Function Code 04 is
selected, the Register Number defaults to 30001.
2. Default Data Type is Float
3. Default Slave ID for PV1=001, for PV2=002, for PV3=003, etc.
Short
Long
The Master ignores the decimal point setting for slave devices that specify a Short or Long integer. For
example, a slave that is displaying 12.34 is read as 1,234. Floating point data may or may not utilize the
decimal point. Refer to the slave’s operating manual to make sure.
The Register Number range is based on the Function Code and the number of digits selected. See the
following table:
Function Code 5 Digit 6 Digit
03 40001 – 49999 400001 – 465536
04 30001 – 39999 300001 – 365536
65 65001-65999 N/A
