Configuration data memory layout
Both OMD devices, evaluator and sensor, use the same MCU type. For the cases when OMD
sensor is used with third party superordinate system instead of OMD evaluator, it is important
to consider configuration data memory layout of sensor device. This is critical for correct con-
figuration parameter set CRC calculation by superordinate system.
Configuration data memory layout features:
•
Little endian data format;
•
16-bit sized parameter data item;
•
2-byte parameter data alignment.
