Sinec-H1 is an Ethernet-based protocol that executes the transport layer function. Developed by Siemens, it is used for telecontrol. Its large bandwidth makes it ideal for the transmission of large data volumes.
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.
