SIEMENS Modbus/TCP Software
MODBUS is a worldwide communication protocol which is open to all users and is used by many manufacturers. On this basis, MODBUS/TCP has been developed for the use in modern networks. In today’s industry, this protocol has become a de facto standard which has been introduced in the Internet Engineering Task Force (IETF) – an organization responsible for Internet standardization.

The SIMATIC Modbus/TCP software packages offer ready-to-use blocks for simple and quick implementation of a MODBUS communication in SIMATIC controllers.
