Select Function (Read Holding Registers).It should appear like in the example and then press Edit. Go back to the Slave configuration window and create Slave request by writing a name, pressing Add button. Type in Slave ID (any number from 1 to 255).Now create RS232 slave by writing a name, pressing Add button. Select Baud rate (9600, it must match slave‘s baud rate).Open router’s WebUI, navigate to Services > Modbus > Modbus Serial Master and apply the following configuration. Select the Port which you connected RS232 cable to (to find which port you are using go to Windows search bar and write Device Manager then select Ports and see which one you are using).Click Setup the communication Serial or TCP/IP port.When you are done with that, open the app and apply the following configuration. To do so you will need to install modRSsim application, which you can download here. In this example we are going to be using our Windows 10 computer as a slave. To find more information about this feature visit RUT955 Modbus and RUT955 RS232/RS485 pages. This article provides a brief example on how to use Modbus serial to monitor a slave device, send data to server and how to configure slave alarms. 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 is often used to connect a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems. 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. moves raw bits or words without placing many restrictions on vendors.developed with industrial applications in mind.The main reasons for the use of Modbus in the industrial environment are: Modbus has become a de facto standard communication protocol and is now a commonly available means of connecting industrial electronic devices. Modbus is a serial communications protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs). 6.2 RUT Modbus data to server configuration. 4 Configuring Modbus serial slave device.NET 4.6 to build a powerful tool with rich features and user friendly GUI. Modbus Examiner makes use of WPF, C#, and. You are free to make use of the tool but keep in mind that the tool is provided AS IS, so I am hereby free of responsibility of any problems that occur from using the Modbus Examiner tool. I provide the tool for download here for free. The tool works in the Windows operating system. Modbus examiner is the product of numerous late night coding sessions, that I invested in order to enrich my knowledge and skills. The tool is capable of performing periodic data pulls to keep your readings up to date. The main purpose of the tool is to read and write data from and to TCP Modbus slave devices. Modbus examiner is an open source TCP Modbus client tool, built from the ground up with newer software technologies and modern user interface.
