PcoMotCon (FB)

FUNCTION_BLOCK PcoMotCon

This function block is designed for controlling a speed-controlled motor. The function block is similar to PcoMot (Fixed speed motor controller), but in addition to PcoMot the function block has build in a PID-controller, and software for manual positioning.

InOut:

Scope	Name	Type	Initial	Comment
Input	SpExt	INT	0	1: External setpoint. Calculated setpoint or output from another PID controller (e.g. PCO_PIDCON) in a cascade control system.
	PV	INT	0	2: Process value (to be controlled). Process value obtained from the system
	Track	BOOL	FALSE	3: Tracking mode. PCO_MOTCON can be set in Tracking mode if Track = TRUE. Output of the controller will be set to TRACK_VALUE. (Track mode has higher priority compared to balancing mode). Track is independent of operation mode of PCO_MOTCON.
	TrackSp	INT	0	4: Tracking value. Output of the controller will be set to TrackSp if Track = TRUE
	Bal	BOOL	FALSE	5: Balancing mode. PCO_MOTCON can be set in Balancing mode if Bal = TRUE and Track = FALSE. Output of the controller will be set to BalSp. Bal is independent of operation mode of PCO_MOTCON.
	BalSp	INT	0	6: Balancing setpoint. Output of the controller will be set to BalSp if Bal = TRUE
	RevAct	BOOL	FALSE	7: RevAct = FALSE, controller will increase output if Setpoint is less than Process value. RevAct = TRUE, controller will decrease output if Setpoint is greater than Process value
	EnAuto	BOOL	TRUE	Enable auto operation of PID controller
	AutoCmdStart	BOOL	FALSE	9: Force the motor to start, IF the motor is in automatic mode. E.g. AutoCmdStart could be
	AutoCmdStop	BOOL	FALSE	10: Force the motor to stop, IF the motor is in automatic. E.g. AutoCmdStop could be
	EnStart	BOOL	TRUE	11: Enable Motor to be started.
	EnStop	BOOL	TRUE	12: Enable motor to be stopped.
	EnAcc	BOOL	TRUE	13: Enable motor to increase speed
	EnDec	BOOL	TRUE	14: Enable motor to decrease speed
	EmcyStart	BOOL	FALSE	15: Emergency start, Motor will start if EmcyStart = TRUE.
	EmcyStop	BOOL	FALSE	16: Emergency stop. Motor will stop if EmcyStop = TRUE.
	ActPos	INT	0	17: Feedback speed of motor, Scaling 0-10000
	Run	BOOL	FALSE	18: Motor is running
	Stop	BOOL	FALSE	19: Motor is stopped
	Rdy	BOOL	TRUE	20: Motor is ready for operation. (Ready=FALSE results in external error)
	Remote	BOOL	TRUE	21: Motor can be controlled from OS (Remote=FALSE means local operation)
	InhibError	BOOL	FALSE	22: InhibError=TRUE : Suppress all alarm. InhibError=FALSE : No suppression
	Alarm1	BOOL	FALSE	23: Auxiliary alarm no. 1
	Alarm2	BOOL	FALSE	24: Auxiliary alarm no. 2
	Alarm3	BOOL	FALSE	25: Auxiliary alarm no. 3
	Alarm4	BOOL	FALSE	26: Auxiliary alarm no. 4
	Alarm5	BOOL	FALSE	27: Auxiliary alarm no. 5
	Alarm6	BOOL	FALSE	28: Auxiliary alarm no. 6
	BehaveOnError	BYTE	0	29: BehaveOnError = 0 Causes the output to remain unaffected in case of a functional error or an external error (Not ready).
	OutputHandling	BYTE	1	30: OutputHandling = 0 Causes the output to be reset at In or Out feedback.
	InhibFctErrTime	TIME	TIME#5s0ms	31: Maximum delay time from OS command to response from process.
	RampTime	TIME	TIME#30s0ms	32: Actuator time. (from 0% to 100 % speed)
	RampActive	BOOL	FALSE	33: RampActive= TRUE activates ramp under manual positioning.
Inout	Scada	PCO_MOTCON_TYPE		34: Structure variable for connection to Scada system
Output	Error	BOOL	FALSE	Operation continues with error. The output ErrorID gives more details about the error.
	CmdStart	BOOL	FALSE	1: Command output Start
	CmdStop	BOOL	FALSE	2: Command output Stop
	Out	INT	0	3: Output to the motor (0-27648)
	OutMax	BOOL	FALSE	4: Output limited to the high value
	OutMin	BOOL	FALSE	5: Output limited to the low value
	ErrorID	ERROR_ID	ERROR_ID.NO_ERROR	6: Err number, Output provides an error identifier if an invalid value was applied to an input
