Name	Unit	Area	Description
eControlMode	Obsolete	E_CTRL_MODE	Switches mode.
bSelSetpoint	Obsolete	[True, False]	Selects one of the two possible setpoints; TRUE selects the standby setpoint.
fW1	°C	LREAL	Setpoint
fW2	°C	LREAL	Standby setpoint (normally less than fW1, bSelSetpoint is used to switch between fW1 and fW2).
fX	°C	LREAL	Actual value
fYManual	%	[-100%, +100%]	Control value in manual mode
bOpenThermocouple	Obsolete	[True, False]	The thermocouple is open when TRUE; must be specified by the hardware.
bReverseThermocouple	Obsolete	[True, False]	The thermocouple is connected with incorrect polarity if TRUE; must be specified by the hardware.
bBackVoltage	Obsolete	[True, False]	The input voltage at the thermocouple is too high if TRUE; must be specified by the hardware
bLeakage	Obsolete	[True, False]	Leakage current was detected if TRUE; must be specified by the hardware.
bShortCircuit	Obsolete	[True; False]	Short circuit was detected if TRUE; must be specified by the hardware.
bOpenCircuit	Obsolete	[True, False]	Open circuit was detected if TRUE; must be specified by the hardware.
fD	Obsolete	LREAL	Actual value of the measured disturbance variable
bCompensateDisturbance	Obsolete	[True, False]	Disturbance compensation is enabled if TRUE.
sParaControllerExternal	Obsolete	Structure	An external controller parameter set was transferred to the controller.
