RS-485 and Modbus

THGO3, THR23, GS23 integrate a RS-485 interface for digital communication as an option feature. Based on Modbus protocol makes the general convenience on PLC, HMI and PC connection. For Modbus protocol information please download the file from website. Besides the PLC, HMI application, the user software provide the device setting and data logging function, it also can free download from website.

Technical Data :

Max. network size : 32 transmitters
Communication : with COM-Port (serial interface) of PC
Max. network expansion : 1200m (3937ft) total length at 9600 baud
Transmission rate : 9600, 19200, 38400, 57600, 115200 Baud
Parity : None, Even, Odd
Data length : 8bit
Stopbit : 1or2 bit
Factory default Station address 1, Data format 9600, N81

Configuration

Download the software from eyc-tech official website, decompress it and execute it. Planning software operating system requirements: Windows XP SP2 or above.

Hardware connection: Connect the THG03 / THR23 / GS23 to PC through USB to RS-485 or RS 232 to RS-485 cenverter
Check the COM port number from Device Manager in Computer Management. e.g. COM1in illustration
Open the Ul, go to function ” Interface” , clickitem ” Config” and then setting COM port, BAUD rate, data format and Station ID, pressed ” Apply” for connection
Scan RS-485 connection
Open the U, go to function ” Interface” , clickitem ” Config” and then setting COM port, pressed ” Scan” bottom for scan devices and pressed ” Close and Export ” when the interested devices found.
Pick up the device that you want to connect to and then press “Apply” to go.
Setting on Analog Output
In the group of OUT1(OUT2), Output tab. Both outputl and output2 related setting could be found
Quantity : Temperature, Relative Humidity, Carbon Dioxide (CO3)
Analog type : Voltage or Current
Analog Range : 0…20 mA /4 … 20 mA (if output current) / 0 … 10 V (if output voltage)
Range for Upper and Lower
Alarm Mode: Check the box if analog output pretends an alarm switch output
Alarm Trigger Point: Upper and Lower
Alarm Output Level: Upper and Lower
Display Panel
In the Monitor tab. There is a large display of available measurements.
Setting on RS-485, Data Transmission Test and environment parameters There are 3 groups in setting tab. The description of each item as below.

The environments as From Room/ Office with the condition as midnight period & nobody status, the CO, concentration usually measured as 400ppm. Thus, eyc-tech use the average statistics values for 7 days to implement Self-Correcting feature. This feature is not adaptive to use in special environment as Factory/ Plant Greenroom where the CO, concentration may keep on high value & keep for long period. Others
