Please help improve the article with a good introductory style. The standard is suitable for multiple configurations like point-to-point, star, mutidropped etc.
IEC CRC source code
The control field data of IEC contains various types of mechanisms for effective handling of network data synchronization. The standard supports some specific protection functions and provides the vendor a facility to incorporate its own protective functions on private data ranges.

Hello, Maybe this will help you, it’s a versatile CRC-calculator: Part 5 provides a communication profile for sending basic telecontrol messages between two systems, which uses permanent directly connected data circuits between the systems. This article provides insufficient context for those unfamiliar with the isc. I’d really like a table driven version, but anything is OK.
