THERMOKON_WRF07_TEMP_HUM_AO2V_REV_A_H (FB)

FUNCTION_BLOCK THERMOKON_WRF07_TEMP_HUM_AO2V_REV_A_H

Representation

General

The setpoint / parameter ‘eDeviceMode’ currently (29.10.2024) only influences the formation of the room setpoint temperature ‘rSetpTemp’ and the setpoint temperature offset ‘rOffset’.

The configuration registers (R2 - R46) or coils (C0 - C6) are always set for operation of the WRF07 as a pure room control unit (i.e. without its own internal regulation).

Setpoint / parameter ‘rOffsetRange’: A change is transmitted immediately without error, however the new offset is only used after a cold start of the WRF07.

This function block can be used for all device types except the ‘4DI’ variant.

Depending on the function code, only a respective maximum number of resources may be read/written:

Read registers: <= 20 registers Write registers: <= 20 registers Read coils: <= 16 coils Write coils: <= 8 coils

Only one temperature sensor is present!!!

* Device configuration *

* Thermokon - Configuration Software *

The configuration can be read and written independently of this function block using Thermokon software ‘WRF07-RS485-MODBUS Version 1.7’. The captured configuration data can be saved in a readable file and transferred to a new device.

* Function Block *

In this function block the configuration is read (see Function 1) and, if necessary, the parameters set here are rewritten (Function 2). Parameters that are not set here remain unchanged. The default values according to the documentation can be restored by Function 3.

* Function 1 *

The current device configuration is stored in registers 0 - 46 or in coils 0 - 6.

This is read a) once at startup b) once at every rising edge on input ‘xUpdateConfigRead’ c) cyclically (time interval ‘tTimeUpdateConfigRead’) d) before every write operation (see Function 2)

read (FC03, FC01) and stored in the arrays ‘_arwKonfiguration_0’, ‘_arwKonfiguration_1’, ‘_arwKonfiguration_2’ and ‘arbyKonfiguration_3’. Additionally, the selected outputs are updated.

* Function 2 *

During operation registers 2 - 46 or coils 0 - 6 are written a) once at startup b) on every value change of the relevant parameters c) once at every rising edge on input ‘xUpdateConfigWrite’

written (FC16, FC15) (arrays ‘_arwKonfiguration_4’, ‘_arwKonfiguration_5’, ‘_arwKonfiguration_6’ and ‘arbyKonfiguration_7’).

This write access must not be performed cyclically because the number of write cycles is limited (EEPROM).

* Function 3 *

The device configuration cannot be restored to factory state; the default values are stored in the arrays ‘_arwKonfiguration_8’, ‘_arwKonfiguration_9’, ‘_arwKonfiguration_10’ and ‘_arbyKonfiguration_11’ and can be loaded/written into the device via input ‘xResDefault’ (rising edge).

* Device setpoints *

* Thermokon - Configuration Software *

The setpoints can be read and written independently of this function block using Thermokon software ‘WRF07-RS485-MODBUS Version 1.7’. The captured setpoints can be saved in a readable file and transferred to a new device.

* Function Block *

In this function block the setpoints are read (see Function 1) and, if necessary, the setpoints specified here are rewritten (Function 2). Setpoints not specified here remain unchanged.

* Function 1 *

The current device setpoints are stored in registers 512 - 517 or in coils 256 - 264.

These are read a) once at startup b) once at every rising edge on input ‘xUpdateActual’ c) cyclically (time interval ‘tTimeUpdateActual’) d) before every write operation (see Function 2)

read (FC03, FC01) and stored in the arrays ‘_arwIstwerte_1’, ‘arbyIstwerte_2’ and ‘arbyIstwerte_3’. Additionally, the selected outputs are updated.

* Function 2 *

During operation registers 512 - 517 or coils 256 - 264 are written a) once at startup b) once at every rising edge on input ‘xUpdateSetp’ c) cyclically (time interval ‘tTimeUpdateSetp’) d) on every value change of the relevant setpoints

written (FC16, FC15) (arrays ‘_arwSollwerte_0’, ‘arbySollwerte_1’ and ‘arbySollwerte_2’).
