CiA 443: Profile for SIIS level-2 devices

The CiA 443 CANopen profile for SIIS level-2 devices covers all simple sensors, multi-functional meters, and valves used in so-called Christmas trees. The default physical layer is ISO 11898-3 compatible. The default bit-rate is 50 kbit/s. The CANopen node-ID is assigned by Layer Setting Services (LSS). The profile specifies a boot-loader mode, and the starting and stopping of application programs. Simple sensors include pressure, temperature, and position sensors as well as inclinometer. It also supports multi-phase flow, wet-gas, oil-in-water and some other complex meters as well as dedicated detectors (e.g. PIG). There is no mapping defined for the four default TPDOs and RPDOs. The PDO communication parameters are pre-defined.
