Note 1: The transition from any state to the Idle state due to i_bActivate=OFF is not shown. However these transitions have the highest priority (0).
Note 2: Within muting substates, transitions due to Error Muting sequence (priority 1), Error Timer (priority 2), Safety demand AOPD (priority 3) or Error Muting
lamp (priority 4) have higher priority than transitions to Muting substates (priority 5). If the FB is in the timing error state, the simultaneous occurrence
of C006H and C007H lead to the C006H state.
Note 3: Muting condition 1-6 and wrong muting sequences are shown in the following.
• Muting conditions: Page 63 Muting conditions
• Wrong muting sequences: Page 63 Wrong muting sequences
Note 4: Time parameter error (condition of transition from 8001H to C005H) is detected in either of the following two cases.
1) i_dDiscTimeEntry has been set to a value less than 0ms or greater than 4 seconds. (0 > i_dDiscTimeEntry OR i_dDiscTimeEntry > 400)
2) i_dMaxMutingTime has been set to a value less than 0ms or greater than 10min. (0 > i_dMaxMutingTime OR i_dMaxMutingTime > 60000)
