    The rolling average operation applies the average at every sample position to the last length samples of the input to determine a new output sample. output[i] = Average(input[i-length+1], …, input[i]) Here the reduction function "average" is used by the reduction behavior "rolling".

  • Page 131: Appendix

    MDA V7 uses the decimal() function automatically for binary operations (e.g. in the function Binary_AND). MDA V8 will emulate this behavior by call- ing the Raw() function. If you use a calculated signal, MDA V8 does not do this and will use the physical value instead.

  • Page 132: Constants

    MDA V8 has a "Symmetric round half up". In MDA V7 the Shift (>>, <<) and binary operations (&, |, ^) use the raw value of a signal. MDA V8 will emulate this by calling the Raw() function. MDA V8 | User Guide...

  • Page 133: Operations Of Type "Single Bit

    Calculated signals of integer type in MDA V7 will be converted into double type in MDA V8. This leads to differences in handling of arithmetical over- flow. E.g. the value ‘-1’ in MDA V7 is represented as '4294967295.00’ which is ((uint32)’-1’), and in MDA V8 is real ‘-1.00’.

  • Page 134: Operations Of Type "Limit Monitoring

    For each limit to monitor, a condition is defined, together with a message to be shown if the limit is not met. For MDA V8 such an operation is migrated into a calculated signal of type Boolean. The associated message will not be migrated.
