After reviewing everyone’s private messages and comments, I found that there is a high demand for information on the Modbus master station, as well as interest in how to use DMA to improve communication efficiency. Lastly, there is also some interest in Modbus TCP. Over the past year, the timeline for introducing this series has … Read more
Modbus TCP is a mainstream communication protocol in the field of industrial Ethernet, based on the TCP/IP protocol stack for data transmission. It simplifies the verification mechanism based on Modbus RTU (relying on the TCP protocol’s own verification instead of CRC16), and implements device addressing and request-response matching in an Ethernet environment through the MBAP … Read more
The Inovance InoProShop software is used for programming its AM500 series PLCs. The communication configuration steps for the AM500 series PLC as a Modbus TCP server (slave) are straightforward, as it integrates standard Modbus TCP function blocks. Below are the detailed steps, divided into server (slave) configuration and client (master) configuration. Typically, the AM500 acts … Read more
1. Mitsubishi’s PLC Modbus TCP master station function is generally implemented through programming, requiring the use of “communication protocol support function“ 1)In the object device connection configuration settings, add “Active connection device” and select “communication protocol“. You need to fill in the local port number, the other party’s IP and the other party’s port number. … Read more
