Message frame being received
Coil Status, Function code 01, this data will come from the Digital Outputs of the IVT.
([01] [01] [01] [02] [d0] [49]).
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] [01] ([01]) ([02]) [d0] [49]
The first two sets of numbers are the same as the previous.
1) The device ID (01)
2) The Function code (01).
3) Data Received---Has 2 sets of numbers a [01] and [02]. 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 Coil Status 01 in
this format.
The [02], 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 IVT, here’s how it breaks down.
Even # or O = N.O. normally open --- OFF
Odd # or 1 = N.C. normally closed --- ON
4) Cyclical Redundancy Check--- CRC, is a number assigned by the computer and cannot be
changed by the user.
Input Status,
Function Code 02, this data will come from the Digital Inputs on the IVT.
For a description of the digital inputs refer to ( Input Status Addresses ) below.

The first two sets of numbers are the same as the previous.
1) Is the device ID 01.
2) The Function code 02.
3) Data sent---will consist of 2 sets of data ([00] [00]), ([00] [01]), the first two sets of
numbers [00] [00] are the address (hex), meaning (Loop back of digital outputs, Mist
Tank Oil Level Sensor Switch, etc). To poll the value output status, type in the address in
the Modscan screen address (hex) box.
