If it is needed to connect a controller to a single slave device, you can establish a serial communication by using an RS-485/USB converter, a PC, and specialized software or terminal. In this case, there’s no need for long testing followed by the analysis of numerous log files. So, ...
How to perform an RS232 loopback test A loopback test is a diagnostic test in which the signal returns to the transmitter after passing through the communication channel in both directions. Simply put, you can use loopback test to determine whether the device is working right. This test al...
Click Test Connect to check whether the device connects to the ECC800-Pro properly. If the connection succeeds, click Confirm. The connected devices are displayed in the Number of connected devices list. If the connection fails, check whether the device is properly connected to the ECC800-Pro,...
i am trying to connect the instruments and PLC(which is have a RS485) with IoT, currently my client have a Delta PLC that is installed in remote location so i can't go there to check the values with Modscan software, Yes i have shared modscan screen shot with you that is taken by...

RS485 remote temp and humidity sensor has two-wire and four-wire connections. The four-wire system can only achieve point-to-point communication, which is rarely used now. Nowadays, the two-wire connection method is mostly used. This wiring method is a bus topology. Up to 32 nodes can be...
RS485 communication configuration Click “Advanced”–”Serial Communication”, select “Enable” of “Enable Serial 485” Type in the relative parameters of baud rate, data bit, stop bit, parity according to your sensors or devices’ parameters. ...
Check Communication Ports Circuit boards with communication ports like Ethernet and RS485 have an increased risk of failure. When communication failure is detected, check for burns or cracked communication ICs or protective components like Zeners. ...
Today you will learn about RS485. If you are familiar withRS232, then you may already know a little bit about it. If not, check out our other blog postWhat is RS232. Just like it’s older brother RS232, RS485 is a form of serial communication. Think of RS485 as the younger, fa...
Digital output (SPI, UART, USB) performed by load cell ADC (analog to digital converter); Serial communication (RS232, RS485). If your PLC or DAQ requires analog output, digital load cell output, or serial communication, you will need a load cell amplifier module. Selecting the amplifier ...
