1. Introduction

The I-7000 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. 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.

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 common features of the I-7021/21P, I-7022, I-7024, I-7024R, M-7022, M-7024, M-7024L, M-7024R, M-7024U and M-7028 modules are as follows:

1. 3000VDC, 2500VDC for M-7024U, inter-module

isolation

2. Programmable power-on value for analog output

3. Programmable slew rate

4. Software calibration

The I-7021 is a single channel analog output module with 12-bit resolution and output read-back function. The I-7021P is similar to the I-7021 but with 16-bit resolution. The I-7022/M-7022 is a 2-channel analog output module with 12-bit resolution and output read-back function. The I-7024/M-7024 is a 4-channel analog output module with 14-bit resolution and supports bipolar voltage output. The M-7024L is a 4-channel analog output module with 12-bit resolution and supports bipolar voltage output. The I-7024R/M-7024R is I-7024/M-7024 added 5-channel digital inputs. The M-7024U is a 4-channel analog output module with 16-bit resolution and supports bipolar voltage output. There is also 4-channel digital inputs and 4-channel digital outputs for the M-7024U. The M-7028 is a 8-channel analog output module with 12-bit resolution.

1.7.5 Wiring Recommendations

 Use 26-12 AWG wire for signal connections.  Strip the wire to a length of 7±0.5 mm.

 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.

I-7021/22/24, M-7022/24/28 User Manual, Rev: B2.3

1.8 Quick Start

To install the module, follow the steps below:

1. For current output, adjust the jumper setting for the

I-7021/21P, I-7022 and M-7022. See Section 1.6 for the jumper settings.

2. Connect the output load. See Section 1.2 for the

terminal assignment and Section 1.7 for the wiring diagram.

3. 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.

4. 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 to the module should be in the range of +10 to +30 VDC.

5. For I-7000 modules, configure the module by sending

the %AANNTTCCFF command. See Section 2.1 for details. To configure the I-7022, the $AA9NTS command must also be sent. See Section 2.24 for details. For M-7000 modules using the Modbus RTU protocol, configure the module using the following Modbus registers: 40485, 40486, and 40487. The Modbus registers started at 40257 are required for configuring M-7022, M-7024U and M-7028. The default settings for the module can be found in Section

1.9.

6. For I-7000 modules, in order to write data to the analog

output channels, send the #AA(data) or #AAN(data) commands to the module. See Sections 2.2 and 2.4 for details. For M-7000 modules using the Modbus RTU

I-7021/22/24, M-7022/24/28 User Manual, Rev: B2.3

protocol, use Functions 06h or 10h to write the data to the analog output channels. See Section 3.6 and 3.8 for details.

7. 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 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.

Please 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).

1.10 Calibration

Warning: It is not recommended that calibration be performed until the process is fully understood.

I-7021/21P Current Output Calibration

1. Set the jumper JP1 to select internal power and connect

a current meter to the current output terminal of the module. If there is no current meter then you can use a voltage meter with a shunt resistor of 250 ohm and

0.1%. The current (I) can be calculated using the equation, I = V (voltage) / 250.

2. Warm up the module for at least 30 minutes.

3. Set the type code to 30, 0 ~ 20 mA. Refer to Section

2.1 for details.

4. Send command to output 4 mA. Refer to Section. 2.2

for details.

5. Repeat to send the trim command and check the meter

until the meter’s reading is nearest to 4 mA. Refer to Section 2.10 for details of sending the trim command.

6. Send the 4 mA calibration command. Refer to Section

2.5 for details.

7. Send command to output 20 mA. Refer to Section. 2.2

for details.

8. Repeat to send the trim command and check the meter

until the meter’s reading is nearest to 20 mA. Refer to Section 2.10 for details of sending the trim command.

9. Send the 20 mA calibration command. Refer to

Sections 2.7 for details.

I-7021/22/24, M-7022/24/28 User Manual, Rev: B2.3

I-7021/21P Voltage Output Calibration

I-7022/M-7022 Current Output Calibration

1. Set the jumper JP1 to select internal power and connect

a current meter to the current output channel 0 terminal of the module. If there is no current meter then you can use a voltage meter with a shunt resistor of 250 ohm and 0.1%. The current (I) can be calculated using the equation, I = V (voltage) / 250.

2. Warm up the module for at least 30 minutes.

3. Set the type code to 0, 0 ~ 20 mA. Refer to Section

2.24 for details.

4. Send command to output 4 mA. Refer to Section. 2.4

for details.

5. Repeat to send the trim command and check the meter

until the meter’s reading is nearest to 4 mA. Refer to Section 2.11 for details of sending the trim command.

6. Send the 4 mA calibration command. Refer to Section

2.6 for details.

7. Send command to output 20 mA. Refer to Section. 2.4

for details.

8. Repeat to send the trim command and check the meter

until the meter’s reading is nearest to 20 mA. Refer to Section 2.11 for details of sending the trim command.

9. Send the 20 mA calibration command. Refer to

Sections 2.8 for details.

10. Repeat steps 1 to 9 for channel 1.

Note:

The M-7022 must be switched to the DCON protocol mode before calibrating. Refer to Sections 1.12.1 and 3.3.4 for details of the switching protocol.

I-7022/M-7022 Voltage Output Calibration

1. Connect a voltage meter to the voltage output channel

0 terminal of the module.

Short the current output terminal for the read-back requirement

2. Warm up the module for at least 30 minutes.

3. Set the type code to 2, 0 ~ 10 V. Refer to Section 2.24

for details.

4. Send command to output 10 V. Refer to Section. 2.15

for details.

5. Repeat to send the trim command and check the meter

until the meter’s reading is nearest to 10 V. Refer to Section 2.18 for details of sending the trim command.

6. Send the 10 V calibration command. Refer to Section

2.21 for details.

7. Repeat steps 1 to 9 for channel 1.

Note:

The M-7022 must be switched to the DCON protocol mode before calibrating. Refer to Section 1.12.1 for details of the switching protocol.
