1. Introduction

The M-2000 and M-6000 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 the DCON and Modbus RTU

protocols. Communication between the module and the

host is via an RS-485 bi-directional serial bus standard.

Baud Rates are software programmable and transmission

speeds of up to 115.2K baud can be selected.

The M-2018-16 and M-6018-16 are analog input modules

that include 16 differential analog input channels. The

voltage input range can be from ±15 mV to ±2.5 V, the

current input range can be either +4 to +20 mA, 0 to +20

mA, or ±20 mA, and types J, K, T, E, R, S, B, N, C, L, M,

LDIN43710 thermocouple can be used for the

thermocouple input. Overvoltage protection of up to 120

VDC is provided. The module also features per-channel

open wire detection for the thermocouple input types, and

provides 4 kV ESD protection as well as 3000 VDC intra-

module isolation.

1.6 Quick Start

To install the module, follow the steps below:

1. Connect the analog input. See Section 1.1 for the

terminal assignment and Section 1.5 for the wiring

diagram.

2. Connect the module to the RS-485 network using the

DATA+ and DATA- terminals. See Section 1.1 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 1.1 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 command. See Section 2.1 for

details. For Modbus RTU protocol, configure the

module using the following functions.

 Sub-function 04h of Function 46h, see Section 3.3.2

 Sub-function 06h of Function 46h, see Section 3.3.4

 Sub-function 08h of Function 46h, see Section 3.3.6

The default settings for the module can be found in

Section 1.7.

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 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

M-2018-16 and M-6018-16 User Manual, Rev: B2.7 7MH-020-B27

13

configuration and reading of data. The DCON Utility

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

the ICP DAS website (http://www.icpdas.com).

1.8 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 to the type you want to calibrate.

Refer to Sections 2.1 for details.

3. Enable calibration. Refer to Section 2.18 for details.

4. Apply the zero calibration voltage/current.

5. Send the zero calibration command. Refer to Section

2.5 for details.

6. Apply the span calibration voltage/current.

7. Send the span calibration command. Refer to Section

2.4 for details.

8. Repeat steps 3 to 7 three times.

Notes:

1. For the M-2018-16 and M-6018-16, connect the

calibration voltage/current to channel 0.

2. When calibrating type 06 for the M-2018-16 and M-

7018-16, a resistor of 125 ohms, 0.1% should be

connected. Refer to Section 1.5 for details.

3. Calibration voltages and currents are shown below.

4. The M-2018-16 and M-6018-16 modules must be

switched to the DCON protocol mode before

calibrating. Refer to Section 3.3.4 for details of the

switching protocol.
