I-7000 and M-7000 DIO User Manual, Rev: B2.7 7PH-013-B27
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 bidirectional 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 I7000 series, with the exception that the M-7000 series offers
extended support for the Modbus RTU protocol.
Some I-7000 modules feature
a new design for the frame
ground and INIT switch as
shown in the figure (rear
view). The frame ground
provides enhanced static
protection (ESD) abilities and
ensures the module is more
reliable. The INIT switch
allows easier access to INIT
mode. Please refer to Sections
A.1 and A.3 for more details.
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.

command. See Section 2.1 for details. For M-7000
modules using the Modbus RTU protocol, configure the
module using the following functions.

Sub-function 04h of Function 46h, see Section 3.7.2

Sub-function 06h of Function 46h, see Section 3.7.4
The default settings for the module can be found in
Section 1.9.
5. To read data from the input channels, send either the
$AA6 or @AA commands to the module. See Sections
2.13 and 2.21 for details. For M-7000 modules using the
Modbus RTU protocol, use Function 02h to read the data
from the input channels. See Section 3.2 for details.
6. To write data to the output channels, send the @AA(data)
command to the module. See Section 2.22 for details.
Refer to Sections 2.3 ~ 2.8 for other setting digital output
commands. For M-7000 modules using the Modbus RTU
protocol, use Function 05h or 0Fh to write the data to the
output channels. See Sections 3.5 and 3.6 for details.

1.12 M-7000 Notes
The main difference between the I-7000 and M-7000 series is
that the M-7000 series has additional support for the Modbus
RTU communication protocol, which is the default protocol
of the M-7000 series. The communication Baud Rates for the
Modbus RTU protocol can be in the range of 1200 bps to
115200 bps, and the parity, data and stop bits are fixed as no
parity, 8 data bits and 1 stop bit.
Modbus functions supported by the module are described in
Chapter 3.
1.12.1 Protocol Switching
To switch to the DCON protocol:
1. Uses sub-function 06h of the function 46h and set byte 8
to a value of 1. See Section 3.7.4 for details.
2. After a power-on reset, the communication protocol will
be changed to DCON.
To switch to the Modbus RTU protocol:
1. Sends the $AAPN command and set N to a value of 1.
Note that for the modules without frame ground, the
INIT* terminal should be connected to the GND terminal,
and for the modules with frame ground, the slide switch
on the rear side of the module should be set to the INIT
position, see the figure on the next page. See Section 2.20
for details.
2. After a power-on reset, the communication protocol will
be changed to the Modbus RTU protocol.
80
I-7000 and M-7000 DIO User Manual, Rev: B2.7 7PH-013-B27
1.12.2 INIT Mode
When the module is powered on, with the rear slide switch set
to the INIT position as shown in the figure below for modules
with frame ground, or with the INIT* pin connected to the
GND pin for modules without frame ground, the module is in
INIT mode, (see Section A.1 for details), and the
communication settings are as follows:
1.
2.
3.
4.
Address: 00
Baud Rate: 9600 bps
No checksum
Protocol: DCON
If communication with the module is not possible, set the
module to the INIT mode and use the above settings to
communicate with the module. To read the current settings,
send the commands $AA2, (see Section 2.10), and $AAP,
(see Section 2.19). To set new settings, send the commands
%AANNTTCCFF, (see Section 2.1) and $AAPN, (see
Section 2.20). The new communication settings will be
effective after the next power-on reset.

I-7000 and M-7000 DIO User Manual, Rev: B2.7 7PH-013-B27
2. DCON Protocol
All communication with I-7000 modules consists of
commands generated by the host and responses transmitted by
the I-7000 modules. Each module has a unique ID number
that is used for addressing purposes and is stored in nonvolatile 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 2.24), which are sent to all
modules, but in both of these cases, the modules do not reply
to the command.
Command Format:
Leading
Character

1.10 (Data Format Setting) and 2.1 for details.
End of command character, carriage return
(0x0D)
I-7000 and M-7000 DIO User Manual, Rev: B2.7 7PH-013-B27
87
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.

The Modbus protocol is developed by Modicon Inc., originally
developed for Modicon controllers. Detailed information can be
found at http://www.modicon.com/techpubs/toc7.html. You can also
visit http://www.modbus.org to find more valuable information.
M-7000 series modules support the Modbus RTU protocol. The
communication Baud Rates range from 1200bps to 115200bps. The
parity, data bits and stop bits are fixed as no parity, 8 data bits and 1
stop bit. The following Modbus functions are supported.

4.1 Communicating with the module
If you attempt to communicate with the module and receive
no response, first check the following:

Ensure that the supplied power is within the range of +10
to +30 V DC. If the supplied power is OK, then the power
LED should be on.

When the module receives a command, the power LED is
set to “off”. The power LED is shown as “on” after the
module responds. This method can be used to check
whether the module has received a command sent from the
host.

If possible, use another device to check whether the host
can communicate with the device through the same RS485 network.

If the host is a PC installed with a Windows operating
system, then execute the DCON Utility to determine
whether the module can be found. The DCON Utility can
be downloaded from the ICP DAS website
http://www.icpdas.com. The DCON Utility
documentation can be found in the ”Getting Started For
I-7000 Series Modules” manual.

Set the module to “INIT mode” and communicate with the
module using the following settings: address 00, Baud
Rate 9600bps and no checksum. See Section A.1 for
details.

A. Appendix
A.1 INIT Mode
Each I-7000 and M-7000 module has a built-in EEPROM to
store configuration information such as module address, type
code, Baud Rate, etc. Occasionally, the configuration of a
module may be forgotten and there are no visual indications
of the configuration of the module. It is difficult to
communicate with the module when the configuration of the
module is unknown. To help avoid this problem, the I-7000
and M-7000 series has a special mode called “INIT mode”.
When the module is powered on in “INIT mode” the
configuration of the module is reset as follows, allowing it to
be operated as normal.
1.
2.
3.
4.
Address: 00
Baud Rate: 9600 bps
No checksum
Protocol: DCON
The configuration information stored in the EEPROM is not
changed and can be read by sending the $002(CR) command
at 9600bps.
There are commands that require the module to be in INIT
mode. They are:
1. %AANNTTCCFF when changing the Baud Rate and
checksum settings. See Section 2.1 for details.
2. $AAPN, see Section 2.20 for details.

I-7000 and M-7000 DIO User Manual, Rev: B2.7 7PH-013-B27
Originally, the INIT mode is accessed by connecting the
INIT* terminal to the GND terminal. New I-7000 and M7000 modules have the INIT switch located on the rear side of
the module to allow easier access to the INIT mode. For
these modules, INIT mode is accessed by sliding the INIT
switch to the Init position as shown below.

A.2 Dual Watchdog Operation
Dual Watchdog = Module Watchdog + Host Watchdog
The Module Watchdog is a hardware reset circuit that
monitors the operating status of the module. While working
in harsh or noisy environments, the module may be shut down
by external signals. The circuit allows the module to work
continuously without disruption.
The Host Watchdog is a software function that monitors the
operating status of the host. Its purpose is to prevent
problems due to network/communication errors or host
malfunctions. When a host watchdog timeout occurs, the
module will reset all outputs to a safe state in order to prevent
any erroneous operations of the controlled target.
I-7000 and M-7000 series modules include an internal Dual
Watchdog, making the control system more reliable and
stable.
For more information regarding the Dual Watchdog, please
refer to Chapter 5 of the “Getting Started For I-7000 Series
Modules” manual that can be downloaded from the ICP DAS
website http://www.icpdas.com.

A.3 Frame Ground
Electronic circuits are constantly vulnerable to Electro-Static
Discharge (ESD), which become worse in a continental
climate area. Some I-7000 and M-7000 modules feature a
new design for the frame ground, which provides a path for
bypassing ESD, allowing enhanced static protection (ESD)
capability and ensures that the module is more reliable.
Either of the following options will provide a better protection
for the module:
1. If the module is DIN rail mounted, connect the DIN rail to
the earth ground because the DIN rail is in contact with the
upper frame ground as shown in the figure below.
2. Alternatively, connect the lower frame ground terminal to
a wire and connect the wire to the earth ground, as shown
in the figure below.
I-7000 and M-7000 DIO User Manual, Rev: B2.7 7PH-013-B27
189
New DIN rail models are available that can easily be
connected to the earth ground. Each is made of stainless steel,
which is stronger than those made of aluminum. There is a
screw at one end and a ring terminal is included as shown in
the figure below. Refer to Section 1.13.1 for more
information about the new DIN rail models.

A.4 Reset Status
The reset status of a module is set when the module is
powered-on or when the module is reset by the module
watchdog. It is cleared after the responding of the first $AA5
command. This can be used to check whether the module had
been reset. When the $AA5 command responds that the reset
status is cleared, that means the module has not been reset
since the last $AA5 command was sent. When the $AA5
command responds that the reset status is set and it is not the
first time $AA5 command is sent, it means the module has
been reset and the digital output value had been changed to
the power-on value.
I-7000 and M-7000 DIO User Manual, Rev: B2.7 7PH-013-B27
191
A.5 Safe Value and Power-on Value of
Digital Output
Besides setting by the set digital output commands, the digital
outputs can be set under two other conditions.
When the host watchdog is enabled and a host watchdog
timeout occurs, the “safe value” is loaded into the digital
output ports. The set digital output commands have no effect
on the digital output ports until the host watchdog timeout
status is cleared. The host watchdog timeout status is saved in
the EEPROM. The status is not changed even after power-on
reset. It can be cleared only by the reset host watchdog
timeout status command ~AA1. See Section A.2 for host
watchdog details.
When the module is powered on and the host watchdog
timeout status is cleared, the “power-on value” is loaded into
the digital output ports. If the host watchdog timeout status is
not cleared on power-on, then the safe value is loaded into the
digital output ports.
Both the safe value and power-on value are set by the ~AA5V
command. Refer to Section 2.30 for details.

A.6 Latched Digital Input
The I-7000 and M-7000 DIO modules provide commands to
read the latched high digital input and latched low digital
input status. Following is an example to show the usefulness
of the latched digital input. When we want to read the key
stroke of a key switch connected to the digital input channel
of a module, the input signal of the key stroke is a pulse signal
as shown in the following figure.
If we just use the read digital input status command to read
the signal and we cannot send the command during the B
period due to some reasons, then we will lose the key stroke
information. However, with the read latched digital input
command, we can still get the key stroke information even we
are not able to send command in B period. For details of the
read latched digital input command, please refer to Sections
2.17 and 3.1.

A.7 DN Module
The DN modules are the I/O extension of the I-7000 and
M-7000 modules. They can drive more power and heavy load.
User may use I-7000 and M-7000 modules to control the DN
modules to drive the loads. Following is an example of using
the I-7043 with the DN module.
