04 = 03 --- High Air Temp.
05 = 04 --- Air Temp.
06 = 05 --- Mist Density
07 = 06 --- Mist Press.
08 = 07 --- Regulated Air Press.
09 = 08 --- Supply Air Press.
a = 09 --- Supply Oil Press.
b = 0a --- High Air Pre-heater Temp.

Message frame being received
Input Register, Function code 04, this data will come from the JD
([01] [04] [02] [00] [44] [b9] [03]).
1) Device I.D. in
Modscan screen has to
be the same as the JD
location
2) In the Modscan
screen Modbus point
type & Function code are
the same thing 3) Data Received,
consisting of length and
the status being polled 4) Cyclical Redundancy
Checking or CRC
[01] [04] ([02]) ([00][44]) [b9] [03]
The first two sets of numbers are the same as the previous.
1) The device ID 01.
2) The Function code 04.
3) Data Received---Has 3 sets of numbers a [02] and a [00] [44]. The first set of numbers [02] represent the
number of bites of the value status being received (black field), meaning the length in the Modscan screen is
1 so a [02] is received in the message frame (black field). If the length in the Modscan screen were 2 the
data received would be [04], if it were 3 then it would be [06] and so on.
The second set of numbers is the value being polled in HEX, Example [00] [44] = 68 in decimal, this is value
that’s received for the Bulk Oil Reservoir Level. (This would be in gallons)
If the length were 2 in the Modscan screen and the starting HEX Address were 02, then from the previous
statement. The data received would be [00] [44] [00] [46]. The first two bites of data [00] [44] bulk Oil
Reservoir Level would have a decimal value of 68 in gallons and the second set of data bites [00] [46] would
be the Ambient Temp. with a decimal value of 70 (this would be degrees in Fahrenheit).
4) Cyclical Redundancy Check--- CRC, is a number assigned by the computer and cannot be changed by
the user.
