◆ SE_SetPID()

int SE_SetPID	(	int	pidID,
		int	controlOutput,
		int	adChannels,
		int	measureUnit,
		int	targetValue,
		int	controlMaxValue,
		int	behavior,
		int	usbDevice
	)

Enable SESTILIO as a temperature controller. Four simultaneous temperature controls are performed at the same time. Default PID time base is 10mS. A Proportional-Integral-Derivative controller (PID-controller) is a negative feedback mechanism widely used in control systems. It is the most common feedback control system used in industry, particularly in PI (not action-derived) version. Thanks to an input that determines the actual value, the system will respond to an eventual positive or negative error and tend towards value 0. As the reaction towards the error can be adjusted, this system is very versatile.

Parameters

pidID	PID identifier. 0 - 3
controlOutput	Specify the PID output. /ref pidctrl
adChannels	Specify the used analog channel for the measurement. If more then one channel is set it calculate an average value for the measurement. PID Analog channel selection
measureUnit	Sets the unit of measure of the target value. When is selected temperature unit you must use as sensor an AD590. PID unit definitions
targetValue	Target value.
controlMaxValue	Maximum value to be used for the PID control.
behavior	0: PID action on value < target (heating), 1: PID action on target < value (cooling).
usbDevice	Specify a SESTILIO USB identifier.

Returns: Operation status. Operation Status
// Set a temperature control using as output DAC0 and as input AD channel 0 and 1 (average will be performed)
// Target temperature will be 270 Kelvin.
// AD590 are used for the temperature measurement.
SE_SetPID(0, SE_PID_OUT_DAC0, SE_PID_CHAN_00 + SE_PID_CHAN_01, SE_PID_UNIT_MK, 270000, 4095, 1, usbDevice);

// Set a temperature control using a power opto-isolated output (PWM mode) and as input AD channel 0
// Target temperature will be 270 Kelvin.
// AD590 are used for the temperature measurement.
SE_SetPID(0, SE_PID_OUT_PWM, SE_PID_CHAN_00, SE_PID_UNIT_MK, 270000, 255, 1, usbDevice);

◆ SE_SetPIDconstants()

int SE_SetPIDconstants	(	int	pidID,
		int	constantId,
		int	constantBase,
		int	constantDivider,
		int	usbDevice
	)

Set some intrinsic PID constants.

Parameters

pidID	PID identifier. 0 - 3
constantId	Constant identifier. PID constants identifier
constantBase	Numerator of the fraction that define the constant.
constantDivider	Denominator of the fraction that define the constant.
usbDevice	Specify a SESTILIO USB identifier.

See also: SE_SetPID, SE_SetPIDtimeBase.

Returns: Operation status. Operation Status

◆ SE_SetPIDtimeBase()

int SE_SetPIDtimeBase	(	int	timeBaseMultiplier,
		int	usbDevice
	)

The PID is a preset value and runs a cycle every 100 mS.This command enables modification of before mentioned value. The cycle time is calculated as follows: T (ms) = N * 100.

Parameters

timeBaseMultiplier	Cycle time divisor.
usbDevice	Specify a SESTILIO USB identifier.

See also: SE_SetPID, SE_SetPIDconstants.

Returns: Operation status. Operation Status
