1. Introduction
The M-2000 series is a family of network data acquisition
and control modules, providing analog-to-digital, digitalto-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, or
the standard Modbus RTU protocol. Communication
between the module and the host is via an RS-485 bidirectional serial bus standard. Baud Rates are software
programmable and transmission speeds of up to 115.2K
baud can be selected.
The M-2000 modules feature a new design for the frame
ground and INIT switch as shown in the figure below.
The frame ground provides enhanced static protection
(ESD) abilities and ensures the module is more reliable.
The INIT switch allows INIT mode to be accessed more
easily. Refer to Sections A.1 and A.3 for more details.
The M-2017 is an 8-channel voltage and current input
module, with the ability to connect various types of inputs
to a single module. It supports for fast mode, 60
samples/second. The M-2017 modules are designed for
industrial plant environments and have special input

Use 26-12 AWG wire for signal connections.
Strip the wire to a length of 7±0.5mm.
Use a crimp terminal for wiring.
Avoid high-voltage cables and power equipment as
much as possible.
For RS-485 communication, use insulated and
twisted pair 24 AWG wire, e.g. Belden 9841.

1.7 Quick Start
To install the module, follow the steps below:
1. Connect the analog input. See Section 1.2 for the
terminal assignment and Section 1.6 for the wiring
diagram.
2. Connect the module to the RS-485 network using the
DATA+ and DATA- terminals. See Section 1.2 for the
terminal assignment. If the host is only equipped with
an RS-232 interface, then an RS-232 to RS-485
converter will be required. Refer to the “I-7000 Bus
Converter User’s Manual” for more information.
3. Connect the module to the power supply using the +Vs
and GND terminals. See Section 1.2 for the terminal
assignment. Note that the voltage supplied should be
in the range of +10 to +48V DC.
4. For DCON protocol, configure the module by sending
the %AANNTTCCFF and $AA7CiRrr commands.
See Section 2.1 and 2.9 for details. For Modbus RTU
protocol, configure the module using the following
Modbus registers: 40257, 40485 and 40486. See
Section 3.4.1 for details.
The default settings for the module can be found in
Section 1.8.
5. For DCON protocol, in order to read data from the
input channels, send either the #AA or #AAN
command to the module. See Sections 2.2 and 2.3 for
details. For the Modbus RTU protocol, use Function
04h to read the data from the input channels. See
Section 3.2 for details.
6. If the host is a PC with a Windows operating system
installed, the DCON Utility can be used to allow easy
configuration and reading of data. The DCON Utility
M-2017 User Manual, Rev: B2.5

can be downloaded from the ICP DAS website
(http://www.icpdas.com). The documentation for the
DCON Utility can be found in the ”Getting Started
For I-7000 Series Modules” manual.
Refer to the “I-7000 Bus Converter User’s Manual”
and ”Getting Started For I-7000 Series Modules”
manuals for more details. The “Getting Started For I-
7000 Series Modules” manual can be downloaded from

1.9 Calibration
Warning: It is not recommended that calibration be
performed until the process is fully understood.
The calibration procedure is as follows:
1. Warm up the module for 30 minutes.
2. Set the type code of channel 0 to the type you want to
calibrate. Refer to Sections 2.9 for details.
3. Enable calibration. Refer to Section 2.17 for details.
4. Apply the zero calibration voltage/current to channel 0.
5. Send the zero calibration command. Refer to Sections
2.5 for details.
6. Apply the span calibration voltage/current to channel 0.
7. Send the span calibration command. Refer to Sections
2.4 for details.
8. Repeat steps 3 to 7 three times.
Notes:
1. When calibrating type 0D for the M-2017, the SW2
switch of channel 0 should be set to the ON position.
2. Calibration voltages and currents are shown below.
3. The M-2000 series modules must be switched to the
DCON protocol mode before calibrating. Refer to
Section 1.11.1 for details of the switching protocol.

1.11 M-2000 Notes
The M-2000 series support for the Modbus RTU
communication protocol, which is the default protocol of
the M-2000 series. The communication Baud Rates for
the Modbus RTU protocol can be in the range of 1200 bps
to 115200 bps.
Modbus functions supported by the module are described
in Chapter 3.
1.11.1 Protocol Switching
To switch to the DCON protocol:
1. Set the Modbus register 00257 to 0. See Section 3.4.1
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 the SW1 INIT switch on the bottom side of
the module should be set to the ON position, see the
figure on the next page. See Section 2.15 for details.
2. After a power-on reset, the communication protocol
will be changed to the Modbus RTU protocol.
M-2017 User Manual, Rev: B2.5
23
1.11.2 INIT Mode
When the module is powered on, with the SW1 INIT
switch set to the ON position as shown in the figure below,
the module is in INIT mode, (see Section A.1 for details),
and the communication settings are as follows:
1. Address: 00
2. Baud Rate: 9600 bps
3. No checksum
4. 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 2.6), and
$AAP, (see Section 2.14). To set new settings, send the
commands %AANNTTCCFF, (see Section 2.1) and
$AAPN, (see Section 2.15). The new communication
settings will be effective after the next power-on reset.

2. DCON Protocol
All communication with M-2000 modules consists of
commands generated by the host and responses
transmitted by the M-2000 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 command ~** (Section 2.23),
which are sent to all modules, but in these cases, the
modules do not reply to the command.
Command Format:
Response Format:
CHKSUM A 2-character checksum that is present
when the checksum setting is enabled. See
Section 1.10 and 2.1 for details.
CR End of command character, carriage return
(0x0D)
M-2017 User Manual, Rev: B2.5
26
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.
