Server srv (Tcp, '127.0.0.1', '1502') // new Modbus Server on TCP/IPīufferedSlave & slv = srv.addSlave (10) // Adding a new slave to the server Slave & slv = mb.addSlave (33) // to the slave at address 33

Master mb (Rtu, 'COM1', '19200E1') // new master on RTU To do this, Modbus::Master is associated with the Modbus::Slave class which allows to perform the read and write operations, here are an example of use: uint16_t values // array to store the values of the input registers That is, Modbus::Master can read or write data to slaves.

The Modbus::Master class allows you to design clients (also called masters), who communicate with servers (also called slaves). Like libmodbus, libmodbuspp is cross-platform and can be compiled on Gnu/Linux and other Unix, Windows™ and macOS™. libmodbussp will be used in version 2 of the utility mbpoll. libmodbussp allows you to implement MODBUS servers and clients. This library supports RTU (serial) and TCP (Ethernet) communications.

libmodbuspp is a free software library to send/receive data according to the MODBUS protocol. Also available is a demoThe libmodbuspp library provides a C++ overlay to libmodbus, a wrapper, having no other dependency than libmodbus and libstdc++. Profiles of the simulated data points, and all OPC interfaceĬalls are displayed in a logging window.
