Input description
FbStat Starter status word. Feedback signal from I/O scanning
ATS_Meas Starter measures. Feedback signal from I/O scanning
The measure variable depends on the rst register address
Output description
QCrtl Starter control word, sent to the starter via I/O scanning
In-output description
(HMI) Structure with command from HMI or SCADA and feedback to HMI or SCADA
Used structures
HMI_MOTOR_B
Auto_Man Bool Command to set the block in Auto or Manu
Run_Stop Bool Command to run or stop the pump
Rst_Fault Bool Command to acknowledge internal and external errors indicated at the output
Error. Acknowledgement is done with a rising edge.
Speed_Output Int Output speed from the ATS.
Meas_1 Int Object to be congured in I/O scanner and to be displayed in HMI
(eg: current, power consumption,…)
Meas_2 Int Object to be congured in I/O scanner and to be displayed in HMI
(eg: current, power consumption,…)
Meas_3 Int Object to be congured in I/O scanner and to be displayed in HMI
(eg: current, power consumption,…)
Meas_4 Int Object to be congured in I/O scanner and to be displayed in HMI
(eg: current, power consumption,…)
Nb_start Int Number of starts performed in the last 24 hours, displayed on HMI
(calculated value)
Min_time_stop Int Minimum time between stop and start
Discrepancy_time Int Maximum time between and order and the right feedback
Time_to_start Dint Time before themotor restart, calculated when
Param_Min_time_stop<>0..
Sts_Auto Bool Automatic mode is activated. The process sequence manages the motor
Sts_Manual Bool Manual mode is activated. The commands come from HMI or SCADA.
Sts_Local Bool Local mode is activated. The commands are hardwired.
Sts_Off Bool The ATS is powered off by the hardwired.
Sts_Locked Bool Indicates that the operation is blocked by an interlock (input Lock).
Sts_Error Bool Indicates that the operation is blocked by an internal or external (Input Err)
error, which is not acknowledged.
Sts_TimerProtect Bool Number start control is activated (Nb_start_day <>0) and the max starts
number is reached.
Sts_ATS_Ready Bool Starter ready to switch on
Sts_ATS_Run Bool The motor is running (Status from starter)
Sts_ATS_PTC Bool Motor monitoring by PTC probe
Sts_ATS_Estop Bool ATS emergency stop activated
Sts_ExtErr Bool External error from the process or the system
Sts_NoVoltage_Err Bool No voltage in ATS
Sts_ATS_Err Bool ATS in error
Sts_Discrepancy_Err Bool Discrepancy error. The discrepancy control is activated
( Discrepancy_time<>0 ).
