T100MD888+ can send out MODBUS ASCII or RTU command to the third party MODBUS device. You need to do the followings:
1. Choose the COMM port to use (COMM1 RS232 or COMM3 RS485, depending on your third party device interface).
2. Use
SETBAUD command to configure the baud rate, number of data bits, start bits and stop bits of the serial port to be the same as the modbus device.
3. In the T100MD888+, execute the
READMODBUS command to send modbus protocols to the 3rd party device to read the analog sensor data.
4. The analog data read into the T100MD888+ variable space is now viewable via the Internet using TRiLOGI or TRi-ExcelLink software. You can also write your own Java applet using our Java API library to access the analog sensor.
