1.Introduction
The I-7000 series is a family of network data acquisition
and control modules, providing analog-to-digital,
digital-to-analog, digital input/output, timer/counter and
other functions. The modules can be remotely controlled
using a set of commands, which we call the DCON
protocol. Communication between the module and the
host is in ASCII format via an RS-485 bi- directional
serial bus standard. Baud Rates are software
programmable and transmission speeds of up to 115.2
Kbps can be selected.The functionality of the M-7000
series is the same as the I-7000 series, with the exception
that the M-7000 series offers extended support for the
Modbus RTU protocol.
The I-7000 and M-7000 DIO modules support TTL
signal,photo-isolated digital input, AC voltage digital
input, relay contact output, solid-state relay output,
photoMOS output and open-collector output.

How do I set the configuration of the modules ?
ICP DAS M-7065 DIO module are command based. A series of
commands are provided to allow the configuration and DI/O
functions to be set. The basic DI/O and configuration commands are
listed below. Refer to the following links for more information.
ftp://ftp.icpdas.com/pub/cd/8000cd/napdos/7000/manual/modbusdio.pdf
The Configuration command structure of the Modbus RTU is as
follows:
*n: This value depends on the Sub-function code. Please refer to the
“Modbus DIO User’s Manual” for more details.
Ex: To modify the power-on value of the module from 01, the
following command should be sent:
01 46 27 0F BB F9
The supported DI/O commands are as follows:
Function code Description
0x01 Read coils
0x02 Read discrete inputs
0x03 Read multiple registers
0x04 Read multiple input registers
0x05 Write single coils
0x0F Write multiple coils

M-7065 User’s Manual Ver2.0, Dec. /2008---14
Ex: To read the current DI value of channels 0 to 5, the following
command should be sent:
01 02 00 00 00 05 B8 09
Ex: To write the DO value 0x0F from channels 0 to 4, the following
command should be sent:
01 0F 00 00 00 04 01 FF 7E D6
Ex: To only set the DO value of channel 2 to 1, the following
command should be sent:
01 05 00 02 FF 00 2D FA
The Configuration command structure of the Modbus ASCII is
as follows:
Command Format:
Response Format:
Using Modbus ASCII Protocol, all command are coded in
hexadecimal values, represented with readable ASCII characters.
Only the characters 0...9 and A...F are used for coding.
Leading

Module
Address Command
[LRC] CR LF
Leading
Character
Module
Address Data [LRC] CR
LF

M-7065 User’s Manual Ver2.0, Dec. /2008---15
Using Modbus ASCII Protocol, characters are used to start and
end a frame. The Leading Character ':' is used to flag the start of a
command and each command is ended with a CR•LF combination.
The LRC characters are appended to the command preceding the
CR•LF characters.
LRC Calculation:
All characters except for Leading Character (:) and delimiter
(CR•LF) are added with a carry being discarded. Total value is
converted to binary notation, is converted to 2’s complements, then
to hexadecimal figures, that is, LRC.
Example :
Modbus RTU => 01 46 00 [ 12 60 ]
Modbus ASCII => :014600B9(CR•LF)
(1.) hexadecimal = 01h+46h+00h = 47h
(2.) 2’s complement: = B9h (LRC)

2. DCON Protocol
All communication with M-7000 modules consists of
commands generated by the host and responses transmitted
by the M-7000 modules. Each module has a unique ID
number that is used for addressing purposes and is stored in
non-volatile memory. The ID is 01 by default and can be
changed using a user command. All commands to the
modules contain the ID address, meaning that only the
addressed module will respond. The only exception to this is
commands #**(Section 2.2) and ~** (Section 2.26), which
are sent to all modules, but in both of these cases, the
modules do not reply to the command.
Command Format:
Leading

CR
CHKSUM 2-character checksum which is present when
the checksum setting is enabled.See Sections
1.1 (Data Format Setting) for details.
CR End of command character, carriage return
(0x0D)

M-7065 User’s Manual Ver2.0, Dec. /2008---19
Checksum Calculation:
1. Calculate the ASCII code sum of all the characters in the
command/response string except for the carriage return
character (CR).
2. The checksum is equal to the sum masked by 0FFh.
Example:
Command string: $012(CR)
1. Sum of the string = “$”+”0”+”1”+”2” =
24h+30h+31h+32h = B7h
2. Therefore the checksum is B7h, and so
CHKSUM = “B7”
3. The command string with the checksum = $012B7(CR)
Response string: !01200600(CR)
1. Sum of the string =
“!”+”0”+”1”+”2”+”0”+”0”+”6”+”0”+”0” =
21h+30h+31h+32h+30h+30h+36h+30h+30h = 1AAh
2. Therefore the checksum is AAh, and so
CHKSUM = “AA”
3. The response string with the checksum
= !01200600AA(CR)
Note:
All characters should be in upper case.
