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.

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-7005 and M-7005 modules are as follows:

1. 24-bit sigma-delta ADC to provide excellent accuracy

2. Direct thermistor connection

3. Software calibration

The i-7005/M-7005 is an 8-channel thermistor input and 6-channel digital output module

i-7005/M-7005 User’s Manual, Rev: B1.8 7MH-018-B18

1.11 User-defined Types

For a typical thermistor, the relationship between resistance and temperature can be expressed by the Steinhart–Hart equation

1/T = A + B lnR

+ C (lnRT)

where RT is the resistance in ohms at temperature T in degrees

Kelvin (K = °C + 273.15). The values of A, B, and C are called

Steinhart Coefficients. The error of the equation is less than +/-

0.01°C in a 100°C span.

i-7005 and M-7005 support user-defined types by specifying the Steinhart coefficients using the @AASxTttC(data) command, see Section 2.30. The data sent is a 32-bit hexadecimal value in IEEE-754 standard format:

Bits Description 31 (sign) 0 = positive, 1 = negative 30-23 (exponent) The exponent base is 2. The actual exponent is

calculated by subtracting 127 from the stored value.

22-00 (mantissa) The mantissa is expressed as 1.f where f is the

fractional part and is stored in this field.

Example: For the hexadecimal value C3694000h

1. Bit 31is 1, indicating a negative number.

2. The value of bits 30-23 is 10000110 binary or 134 decimal. The exponent is 7, 134-127.

3. The mantissa is 1.11010010100000000000000 binary.

4. Adjust the mantissa for the exponent. The adjusted mantissa is 11101001.0100000000000000 binary. That is 233.25 decimal.

5. Considering the sign bit. The floating-point number of C3694000h is –233.25.

The following methods can be used to obtain the Steinhart Coefficients of a thermistor.

i-7005/M-7005 User’s Manual, Rev: B1.8 7MH-018-B18

1. Ask the manufacturer. Usually, thermistor manufacturers publish data for the Steinhart Coefficients for their thermisotr products.

2. Solve the coefficients by using three known data sets: (R1, T1), (R2, T2) and (R3, T3), which can be obtained by referring to the published Resistance versus Temperature data table of the thermistor. They can be obtained by measurement if no published data table is available. In order to achieve the most accurate results, the following values are recommended:

-40°C ≦ T1, T2, T3 ≦ 150°C and |T2 – T1| ≦ 50°C, |T3 – T2| ≦ 50°C.

The DCON Utility, available for downloaded from the ICP DAS website (

http://www.icpdas.com), can assist with the calculation

of the Steinhart Coefficients and the conversion to IEEE-754 format. Documentation for the DCON Utility can be found in

the ”Getting Started For i-7000 Series Modules” manual.

1.12 Digital Outputs and Alarms

The i-7005/M-7005 supports digital outputs that can also be used as alarm outputs. When a host watchdog timeout occurs, the “safe value” is loaded into the digital output ports. The digital output command @AADODD, see Section 2.36, has no effect on the digital output ports until the host watchdog timeout status is cleared. See Section A.2 for host watchdog details. If the host watchdog timeout status has not been cleared when the module is powered on, then the safe value is loaded into the digital output ports. Otherwise, the “power-on value” is loaded into the digital output ports.

The alarm function is performed by comparing the analog input value to the high/low limits stored in the non-volatile memory. The result of the limit check can then be used to control a digital output port. All digital output ports can be used as an alarm output and are programmable. When a digital output port is associated with an alarm, it is not affected by the safe value, power-on value or the digital output command @AADODD. There are two types of alarm:

1. Momentary alarm: The alarm status is set only when

the analog input value exceeds the alarm limitation. When the analog input value is within the limit, the alarm status is cleared.

2. Latched alarm: The alarm status is set when the analog

input value exceeds the alarm limitation. After that, it is cleared only when the clear latched alarm command

is sent. Use the set high/low alarm commands, see Sections 2.37 and 2.38, to set the alarm limit, alarm type, alarm checking channel and alarm port.

1.13 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.

1.13.1 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 3.6.4 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 M-7005, 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 2.19 for details.

2. After a power-on reset, the communication protocol will be changed to the Modbus RTU protocol.

i-7005/M-7005 User’s Manual, Rev: B1.8 7MH-018-B18

1.13.2 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 the M-7005, 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 2.7), and $AAP, (see Section 2.18). To set new settings, send the commands %AANNTTCCFF, (see Section 2.1) and $AAPN, (see Section 2.19). The new communication settings will be effective after the next power-on reset.

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 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 2.43), which are sent to all modules, but in both of these cases, the modules do not reply to the command.

Command Format:

Leading

Data [CHKSUM] CR

CHKSUM A 2-character checksum which is present

when the checksum setting is enabled. See Sections 1.10 (Data Format Setting) and 2.1 for details.

CR End of command character, carriage return

(0x0D)

i-7005/M-7005 User’s Manual, Rev: B1.8 7MH-018-B18

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.

status, the ~AAI and %AANNTTCCFF

commands should be sent consecutively and the

time interval between the two commands should

be less than the soft INIT timeout. If the soft

INIT timeout is 0, then the Baud Rate and

checksum settings cannot be changed using

software only. The power-on reset value of the

soft INIT timeout is 0.

Command: %0101000700 Response: ?01

Attempts to change the Baud Rate of module 01 to 19200 without first altering the INIT * status. The module returns an invalid response because the soft

INIT timeout value is 0. Command: ~01T10 Response: !01 Sets the soft INIT timeout value of module 01 to 16

seconds and returns a valid response. Command: ~01I Response: !01

Sets the soft INIT of module 01 and returns a valid

response. Command: %0101000700 Response: !01

Changes the Baud Rate of module 01 to 19200

without first altering INIT * status. The module

returns a valid response.
