State diagram
State transition of M+SF_MUTEP_R
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 or 6).
If the FB is in the timing error state, the simultaneous occurrence of C006H and C007H or C006H and C008H leads to C006H.
Note 3: Muting condition 1-6 and wrong muting sequences are shown in the following.
• Muting conditions:  Page 71 Muting conditions (forward direction), Page 72 Muting conditions (backward direction)
• Wrong muting sequences: Page 73 Wrong muting sequences
Note 4: Time parameter error (condition of transition from 8001H to C005H) is detected in one of the following three cases.
1) i_dDiscTime11_12 has been set to a value less than 0ms or greater than 4 seconds. (0 > i_dDiscTime11_12 OR i_dDiscTime11_12 > 400)
2) i_dDiscTime21_22 has been set to a value less than 0ms or greater than 4 seconds. (0 > i_dDiscTime21_22 OR i_dDiscTime21_22 > 400)
3) i_dMaxMutingTime has been set to a value less than 0ms or greater than 10min. (0 > i_dMaxMutingTime OR i_dMaxMutingTime > 60000)
