Basic functions:Support standard MODBUS devices such as text, touch screen and PLC with USB interface

• 32-channel thermocouple temperature output, minimum measurementPrecision Zero point onedegree C, no transmitter, direct thermocouple measurement, automatic temperature compensation.

• 1-way 485 communication port, optoelectronic isolation (supporting modbus-RTU protocol)

• 1-way USB interface, directly connected to the computer

• 1 RJ45 Network Interface, Direct Connection to Computer, Routing, etc.(Support modbus-TCP protocol)

• Thermocouple temperature range:From -200 to +1300 C

Data frame format description

1(Home Station Request Message)

Note 1: Sample host request message, read a hold register starting from 0 (4X0001).

For example: 01 03 00 00 00 10 44 06 (read the temperature values of the 1st to 16th routes)

2(slave station normal response message)

Note 1: N = the number of bytes of data in the response.

notes2The output data read from the example of normal response message of slave station is0x00DAThe corresponding temperature is:216 / 10 = 21.6Degree (Temperature:T = data / 10)

For example:01032000 DA00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 CRC(The temperature of the first route is 21.6 degrees)

1.1Module Parameter Modification Tool uuuuuuuuuuuNM_T.exeSoftware

Preparation tools:USBturn485Connect, orUSBConnecting cable (public to public) cable, computer,NM_T.exeSoftware.

Step one:adopt232perhapsUSBConnect cables to connect computers and modules.

The second step:Find the computerNM_T.exeSoftware/ /User manual/soft_software kit/NM_T.exeDouble click to open.

The third step:Select corresponding serial portClick the Connect Host button.The text file on the right will be prompted accordingly. Only after the prompt is successful can the parameters be set, otherwise errors will be prompted.

Step 4: Modify the correspondingMODBUSAddress and baud rate, click the "Set parameters" button. The blank area on the right side will prompt the operation status, and when the prompt is successful, it will indicate the setting.Set parameters successfullyPlease try to select the parameters in the drop-down menu, because the parameters entered manually may be invalid, which will cause the settings to be unsuccessful.

The fifth step:After prompting to set the parameters successfully, click on the uuuuuuuuuuuComplete exit"Button, exit the settings status.When the module is restarted, the corresponding parameters are updated.
