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 the number of digits being used
and then the Up arrow to change the setting for the
number of digits to be used for that register
(
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.
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
