Output Description

Function Block TECT_TEMP_CONTROL

ERR (error)

Data type: BOOL

Output ERR indicates, whether an error occurred during control processing. In case of error, the error number can be read at output ERNO.

ERNO (error number)

Data type: WORD

Output ERNO provides an error identifier, if an invalid value was applied to an input or if an error occurred during request processing.

DUTY_CYCLE

Data type: INT

PWM (Pulse Width Modulation) output DUTY_CYCLE is displayed in percentage.

Positive value indicates heating, negative value indicates cooling.

DO_HEAT

Data type: BOOL

Pulse output for heating process. This variable can be connected to the digital output signal.

DO_COOL

Data type: BOOL

Pulse output for cooling process. This variable can be connected to the digital output signal.

HIGHHIGH

Data type: BOOL

This variable is TRUE, when output HIGHHIGH temperature error is active. The limit value is declared in the data type TECT_TEMPZONE_DATA_TYPE. Temperature Control Library

High temperature alarm and HighHigh temperature fault.

HIGH

Data type: BOOL

This output variable is TRUE, when HIGH temperature alarm is active. The limit value is declared in the data type TECT_TEMPZONE_DATA_TYPE. Temperature Control Library

LOW

Data type: BOOL

This output variable is TRUE, when low temperature alarm (LOW_TEMP) is active. The limit value is declared in the data type TECT_TEMPZONE_DATA_TYPE. Temperature Control Library

Example for LowTemp alarm and LowLowTempFault alarm.

LowTemp alarm, LowLowTempFault alarm

LOWLOW

Data type: BOOL

This output variable is TRUE, when LOWLOW temperature error is active. Limit value is declared in the data type TECT_TEMPZONE_DATA_TYPE. Temperature Control Library
