Message frame being received
Input Status, Function code 02, this data will come from the Digital Inputs from the JD
([01] [02] [01] [80] [a0] [28]).
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]
[02]
([01]) ([80])
[a0] [28]
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 02.
3) Data Received---Has 2 sets of numbers a [01] and [80]. The [01] represents the number of bites of value
status being received (black field), meaning for every single digit added to the length in the Modscan
screen the value status received (black field) will increase by two, except in function codes 01 (Coil
Status) and 02 (Input Status) in this format. Only one value can be polled at a time, so it is recommended
to leave the length at 1 when working in Input Status 02 in this format.
The [80] is the value status of the address being polled.
The status of the address being polled doesn’t necessarily mean it is going to come back in the form of a
1 or 0, on or off. It can also come back in the form of Odd # or Even #, but break down those numbers in
binary form and they will be 1 or 0. From the JD, here’s how it breaks down
The status of components in the Input Status is the opposite of the Coil Status.
Even # or 0 = N. C. normally closed or ON
Odd # or 1 = N. O. normally open or OFF
4) Cyclical Redundancy Check--- CRC, is a number assigned by the computer and cannot be changed by
the user.
