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

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.

M-7026 User Manual Rev: 1.5 Date: 2016/03/10

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.

M-7026 User Manual Rev: 1.5 Date: 2016/03/10

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.
