Software package for the development of Modbus-TCP Server devices

The Modbus-TCP Stack allows the fast and easy development of Modbus-TCP server devices. At this, the software supports the conformance classes 0 and 1 as well as parts of the conformance class 2.

To enable the best possible integration of the protocol software into the customer application, various options for configuration and adaptation of the software are available. This includes e.g. the possibility to manage the Primary Table data either by the customer application or directly within the software stack. The TCP/IP connection management is completely managed by the Modbus-TCP Server protocol software.

Due to independent abstraction layers for the operating system and the TCP/IP software, the Modbus-TCP Server protocol stack can be adapted easily and fast to various microprocessors or operating systems.
