Message frame being received
Holding Register, Function code 03, Refers to the setpoints from the IVT
([01] [03] [02] [07] [cf] [fa] [20]).
1) Device I.D. in
Modscan screen has
to be the same as the
IVT 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] [03] ([02]) ([07] [cf]) [fa] [20]
The first two sets of numbers are going to be the same as the previous.
1) Is the device ID 01.
2) The Function code 03.
3) Data Received---Has 3 sets of numbers a [02] and a [07] [cf]. The first set of numbers [02]
represent the number of bites of the value status being received (black field), meaning for every
single digit added to the length in the Modscan screen two bites of data will be received, so if the
length is 1 in the Modscan screen, a [02] is sent back in the message frame being received (black
field). If the length in the Modscan screen were 2 the data sent back 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 [07] [cf] in hex is 1999 in
decimal, and this is the number identifier for that particular IVT. If the length were 2, in the
Modscan screen, from the statement previous, the data received would be [07] [cf] [00] [78]. It
would send back the first 2 sets of values in the Holding Registry from Address (HEX) 0001 which
