Inputs

VAR_INPUT
    bMovePos       : BOOL;
    bMoveNeg       : BOOL;
    fManSyncValue  : FLOAT;
    bSync          : BOOL;
    eMode          : E_CTRL_MODE;
END_VAR

Name	Type	Description
bMovePos	BOOL	Input that moves the simulated actuator in the positive direction.
bMoveNeg	BOOL	Input that moves the simulated actuator in the negative direction.
fManSyncValue	FLOAT	Input with which the simulated motor position can be set, or the value to which movement takes place in manual mode.
bSync	BOOL	A rising edge at this input sets the simulated motor position to the value "fManSyncValue".
eMode	E_CTRL_MODE	Input that specifies the operation mode of the function block.

Outputs

VAR_OUTPUT
    fMotorPositon      : FLOAT; 
    fMotorState        : FLOAT; 
    bUpperLimitSwitch  : BOOL;
    bLowerLimitSwitch  : BOOL;
    eState             : E_CTRL_STATE;
    eErrorId           : E_CTRL_ERRORCODES;
    bError             : BOOL;
END_VAR

Name	Type	Description
fMotorPositon	FLOAT	Simulated motor position in the range [ fMovingRangeMin ... fMovingRangeMax ]
fMotorState	FLOAT	Simulated motor position in the range [ 0 … 100.0 ]
bUpperLimit Switch	BOOL	Simulated limit switch at the actuator's positive stop
bLowerLimit Switch	BOOL	Simulated limit switch at the actuator's negative stop.
eState	E_CTRL_ STATE	State of the function block
eErrorId	E_CTRL_ERRORCODES	Supplies the error number when the output `bError` is set.
bError	BOOL	Becomes TRUE, as soon as an error occurs.

    stParams        : ST_CTRL_SERVO_MOTOR_SIMULATION_PARAMS;
END_VAR

Name	Type	Description
stParams	ST_CTRL_ SERVO_MOTOR_SIMULATION_ PARAMS	Parameter structure of the function block

stParams consists of the following elements:

TYPE ST_CTRL_SERVO_MOTOR_SIMULATION_PARAMS:
STRUCT
    tCtrlCycleTime   : TIME := T#0ms; 
    tTaskCycleTime   : TIME := T#0ms; 
    fMovingRangeMin  : FLOAT := 0;
    fMovingRangeMax  : FLOAT := 0;
    tMovingTime      : TIME := T#0ms;
    tDeadTime        : TIME := T#0ms; 
END_STRUCT
END_TYPE

Name	Type	Description
tCtrlCycleTime	TIME	Cycle time with which the control loop is processed. This must be greater than or equal to the TaskCycleTime. The function block uses this input value to calculate internally whether the state and the output values have to be updated in the current cycle.
tTaskCycleTime	TIME	Cycle time with which the function block is called. If the function block is called in every cycle this corresponds to the task cycle time of the calling task.
fMovingRange Min	FLOAT	Minimum position of the simulated actuator
fMovingRange Max	FLOAT	Maximum position of the simulated actuator
tMovingTime	TIME	The time required to move the simulated actuator from one stop to the other.
tDeadTime	TIME	Dead time of the simulated actuator
