Introduction

Modbus enables communication among many devices connected to the same network, for example, a system that measures temperature and humidity and communicates the results to a computer. Modbus is often used to connect a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems.

Many of the data types are named from its use in driving relays: a single-bit physical output is called a coil, and a single-bit physical input is called a discrete input or a contact.

Modbus Service is a Windows/Linux system service for WISE Agent to read sensor data from Modbus device or write data into Modbus device. After sensor data are acquired, WISE Agent will upload the data to the WISE-PaaS Cloud.

 

 

Features

EdgeSense Modbus-Master aims to collect data from Modbus Slave.

Feature:

  • Support connection with multiple Modbus slave.
  • Support access both Modbus TCP and RTU in one service.
  • Support individual read interval by connection.
  • Configurable sensor alias.
  • Support byte swap.
  • Support Modbus Coil, Descrete input, Input register & Holding register data.
  • Support maximal 10 links, 5 devices for each link, and 10 sensors for each device.
