Modbus is a Serial Communication protocol which was discovered by Modicon in 1979 and it is used for transmitting data over serial lines between the industrial electronic devices. RS-485 Modbus uses ...
The bridge listens on a configurable TCP port (default: 502) and expects standard Modbus TCP frames from clients. Each request is translated into a Modbus RTU frame, transmitted over UART, and the ...
Splitting single read/write requests into multiple requests with valid number of memory elements. Automatic reconnection to device. Support of multiple devices on the same serial port (VISA ...
BEKA associates have introduced three short video tutorials to assist the development of hazardous area applications using their BA484D and BA488C intrinsically safe serial text displays. These ...
This article provides an overview of both protocols and discusses their key strengths and applications. It also discusses which one works best in which applications – although there is some overlap in ...
Designed by Namnam in Vietnam, the ESP32 Modbus gateway is built to communicate with PLCs and industrial sensors over Modbus RTU (RS-485) or Modbus TCP/IP (Ethernet/Wi-Fi). Designed for use in farms, ...
LumenRadio has recently introduced a Wireless Modbus (W-Modbus) module built around Nordic Semiconductor’s nRF52840 SoC. The module can connect up to 100 nodes, integrates a power amplifier with 100mW ...
