1. Introduction
A number of M-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 (ESD) protection abilities
and ensures that the module is
more reliable. The INIT switch
allows easier access to INIT mode.
Refer to Sections 5.1 and 5.3 for
more details.
The M-7000 series is a family of network data acquisition and
control modules that provide 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
called 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 common features of the M-7000 series are as follows:
1. Voltage or Current Input
2. +/-240 Vrms Overvoltage Protection
3. High Resolution: 16-bit
4. 2500 VDC Intra-module Isolation
5. Photocoupler Isolation
6. Support for Relay Outputs
7. DIN-Rail Mountable
8. Dual Watchdog
9. Wide Operating Temperature Range: -25 to +75°C

Warning: It is not recommended that calibration be performed until the
process is fully understood.
1.8.1 Analog Input
The Analog Input calibration procedure is as follows:
1. Warm up the module for 30 minutes.
2. Set the Type Code to the type you wish to calibrate. Refer to
Section 2.18 for details.
3. Enable calibration. Refer to Section 2.47 for details.
4. Apply the zero calibration voltage/current.
5. Send the Zero Calibration command. Refer to Section 2.8 for
details.
6. Apply the span calibration voltage/current.
7. Send the Span Calibration command. Refer to Section 2.6 for
details.
8. Repeat steps 3 to 7 three times.
Notes:
1. The calibration voltage/current source should be connected to
channel 0.
2. When calibrating Type Code 0D, the jumper for channel 0 should
be set to the “current input” position.
3. Calibration voltages and currents are shown below.

2. Set the Type Code to the type you wish to calibrate. Refer to
Section 2.23 for details.
3. Enable calibration. Refer to Section 2.47 for details.
4. Set the zero Analog Output voltage/current. Refer to Section 2.5
for details.
5. Check the meter and trim the output until zero output is achieved.
Refer to Section 2.11 for details.
6. Send the Analog Output Zero Calibration command. Refer to
Section 2.7 for details.
7. Set the span Analog Output voltage/current. Refer to Section 2.5
for details.
8. Check the meter and trim the output until the span output is
achieved. Refer to Section 2.11 for details.
9. Send the Analog Output Span Calibration command. Refer to
Section 2.9 for details.
Notes:
1. For Analog Output channels, calibration must be performed for
each channel individually, so the calibration voltage/current
source should be connected to the specific channel that is to be
calibrated.
2. When calibrating Types Codes 0 and 1, the jumper for the
corresponding channel should be set to the “current input”
position.
3. Calibration voltages and currents are shown below.

1.10 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.
1.10.1 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 3.4.4 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
the slide switch on the rear side of the module should be set to
INIT position, see the figure on the next page. See Section 2.34
for details.
2. After a power-on reset, the communication protocol will be
changed to Modbus RTU protocol.

1.10.2 INIT Mode
When the module is powered on, with the rear slide switch set to
INIT position as shown in the figure below, the module is in INIT
mode (Section 5.1), 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
INIT mode and use the above settings to communicate with the
module. To read the current settings, send the commands $AA2
(Section 2.10), and $AAPN (Section 2.34). The new
communication settings will be effective after the next power-on
reset.

All communication with the M-7026 module consists of commands
generated by the Host and responses transmitted by the module.
Each module has a unique ID number that is used for addressing
purposes and is stored in non-volatile memory. The ID is set to 01
by default and can be changed by sending the appropriate user
command. All commands to the modules contain the ID number as
the address, meaning that only the addressed module will respond.
There are two exceptions to this, however: the #** command
(Section 2.2) and the ~** command (Section 2.36), which is sent to
all modules, but, in these cases, the modules do not respond to the
command.
Command Format:
Response Format:
CHKSUM A 2-character checksum that is present when the
checksum setting is enabled. See Sections 2.1 and 5.1
for details.
CR End of command character, carriage return (0x0D)
Calculating the Checksum:
1. Sum the ASCII codes of all the characters contained in the
command/response string, except for the carriage return
character (CR).
2. The checksum is equal to the sum value masked by 0FFh.

Example:
Command $012(CR)
1. The sum of the string = “$” + “0” + “1” + “2” = 24h+30h+31h+32h
= B7h
2. Therefore the checksum is B7h, and so CHKSUM = “B7”
3. The DCON command string with the checksum = $012B7(CR)
Response !01200600(CR)
1. The 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 DCON response string with the checksum
= !01200600AA(CR)
Note:
All characters should be expressed in upper case.

2.1 %AANNTTCCFF
Description:
This command is used to set the configuration for a specific module.
Syntax:
%AANNTTCCFF[CHKSUM](CR)
% Delimiter character
AA The address of the module to be configured in hexadecimal format
(00 to FF)
NN The new address of the module in hexadecimal format (00 to FF)
TT Not used by the M-7026 and should be set to 00.
CC The new Baud Rate code, see Section 1.9.1 for details. To change
the Baud Rate, the module should first be switched to INIT* mode.
FF The command used to set the data format, checksum, and filter
settings. See Section 1.9.3 for details of the data format. To change
the checksum settings, the module should first be switched to INIT*
mode.
Response:
Valid Command: !AA[CHKSUM](CR)
Invalid Command: ?AA[CHKSUM](CR)
! Delimiter character to indicate a valid command
? Delimiter character to indicate an invalid command
(Note that if the Baud Rate or checksum settings are changed without
first switching to INIT* mode, the module will return a response
indicating that the command was invalid.)
AA The address of the responding module in hexadecimal format (00 to
FF)
There will be no response if the command syntax is incorrect, there is a
communication error, or there is no module with the specified address.
Note:
Changes to the address, Type Code, Data Format and Filter settings take
effect immediately after a valid command is received. Changes to the Baud
Rate and checksum settings take effect at the next power-on reset.
Examples:
Command: %0102000600 Response: !02
Changes the address of module 01 to 02 and returns a response
indicating that the command was successful.
Command: %0202000602 Response: !02
Sets the data format for module 02 to type 2 (2’s complement
hexadecimal). The module returns a response indicating that the
command was successful.
