Remember: In the Modscan screen Address (hex) 0001 means 00 in the message frame,
0002—01, etc.
The second set of numbers [00] [01] are the (length). In Input Status, only one value can
be polled at a time, it is recommended to leave the length at 1 when working in Input
Status for this format.
4) Cyclical Redundancy Check--- CRC, is a number assigned by the computer and cannot
be changed by the user.
Function code 02—in Modscan screen the address in HEX and the length cannot exceed 11
Or an error will occur in the receiving information in the form of ([01] [82] [00] [40] [a0]), the [82]
being the error code.
Input Status Addresses;
There are only 10 addresses (HEX) available in input status.
Address (HEX) Message frame address Description
01 = 00 -- Loopback of digital output #1
02 = 01 --- Loopback of digital output #2
03 = 02 -- Loopback of digital output #3
04 = 03 --- Loopback of digital output #4
05 = 04 --- Loopback of digital output #5
06 = 05 --- Loopback of digital output #6
07 = 06 -- Not Used
08 = 07 --- Mist Tank Oil Level Sensor
Switch
09 = 08 --- Mist Tank Low Oil Level
Sensor Switch
0a = 09 --- De-Mist Tank High Oil Level
Message frame being received
Input Status, Function code 02, this data will come from the Digital Inputs from the IVT
([01] [02] [01] [80] [a0] [28]).
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] [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.
