emModbus

emModbus supports building master and slave devices which can even be combined in the same product. Also, multiple interfaces in the same product are supported. Each interface can be configured at runtime, making it possible to build a pretested library to be deployed in multiple projects for embedded solutions.

Requirements

TCP/IP stack

For usage of Modbus/TCP, emModbus requires a TCP/IP capable stack. emModbus can be used with any TCP/IP stack that supports BSD Standard Sockets.

Multi-tasking

Although emModbus can be used completely without a RTOS, it is recommended to use emModbus in a multi-tasking system, at least when implementing a Modbus master.
