====== lamaPLC Communication: Sinec H1 ======
**Sinec H1** is an [[com:basic_ie|Industrial Ethernet]] communications protocol that provides the transport layer function widely used in automation and process control applications. The protocol was developed by //Siemens// and is used mainly for control applications. It has large bandwidth and is well suited to the transmission of large volumes of data.

It is based on the ISO/IEC 8073 standard which defines different transport methods. Sinec-H1 applies class 4 (CONS or Connection Mode Network Service).

This protocol has no application layer, which is defined in a project or product-specific way. The application layer protocols XMAT and Simadyn-D need to be mentioned in this context.

It is used as part of the control infrastructure of CERN and LHC.

Sinec H1 was introduced with Siemens' Simatic-S5 series. Sinec H1 was replaced by [[com:basic_profibus|Profibus]] as //"basic communication"// at Siemens, when the Simatic-S7 PLC family was introduced.
