THERMOKON_WRF06 (FB)FUNCTION_BLOCK THERMOKON_WRF06
Short description
Control of the device series WRF06 from Thermokon Typical application: room control unit in a zone\
Guidelines - Software creation
The following function codes (FC) are supported: 1 - 6, 15 - 16 For addressing, use the address specifications, not the register addresses. This room control unit can be delivered in different device types (without / with integrated temperature controller). The function block supports up to four digital inputs and two analog outputs. The two analog outputs can be written to directly. The four function keys F1 (right) - F4 (left) are supported by the function block. The function block exclusively supports use as a pure room control unit; the internal PI controller (present depending on device type) is not used. Calibration of the room temperature sensor is performed either on the room control unit (parameter mode, see documentation) or using the configuration software ‘WRF06-RS485_MODBUS_V_2_9’. The RCU monitors Modbus communication. If no valid Modbus telegram is received for more than 90 s, the analog/digital outputs are set to standard values (registers 53 and 54). Modbus addresses 1 - 32 can be set directly on the DIP switches in the RCU. The address range 1 - 247 can be used by a procedure described in the documentation. In the data area (ADR - FC - data area - CRC1 - CRC2) a maximum of 100 bytes (= 50 registers) may be transmitted (deviating from the Modbus standard). The following transmission parameters were tested: 19200 Baud, 8-N-1 Currently this function block only supports the device types ‘AO2V’ and ‘4DI’ with printing type 2. Setpoint temperature 1 can be changed using the UP / DOWN keys only during day operation (= comfort / occupied) (property of the room control unit) For the internal PI controller the following quantities are used: Actual value: address 258 (= room temperature) Setpoint: address 260 (= effective setpoint 1) Control signal: the control signal is output directly to the outputs. Measured values - calibration: Class 4
Configuration data
The data in the EEPROM (= configuration data) may be written a maximum of 10000x!!! Data in the EEPROM: Addresses 2 - 58: configuration registers Addresses 768 - 987: text message line 1 and 2 Addresses 1024 - 1080: unit line 1, 2 and 3 Coils 0 - 30: configuration bits These configuration data can be read from the room control unit, backed up, changed and written to a new room control unit using the software ‘WRF06-RS485_MODBUS_V_2_9’. Therefore no configuration data are present in the function block. In the function block addresses 0 - 58 are read if the configuration (xUpdateConfig, tTimeUpdateConfig, once after restart) is read. The device configuration cannot be reset to factory defaults (neither via Modbus nor using the configuration software). Register 528 (address 527) - preset of fan stage (FC06 / FC16): If a manual fan stage (0 - 3) is specified, it is displayed and reported back correctly on the RCU. If an automatic fan stage (65280 - 65283) is specified, it is — briefly — displayed and reported back correctly on the RCU. However, the write operation with an automatic stage activates the internal automatic mode which depends on the heating/cooling control signal (adjustable thresholds). Therefore this function block only supports the specifications of manual fan stages. Interfaces \

Function description
General
This function block controls room control units of the WRF06 device series from Thermokon via Modbus communication. Configuration is performed externally, e.g. by using the configuration software ‘WRF06-RS485_MODBUS_V_2_9’. Currently this function block only supports the device types ‘AO2V’ and ‘4DI’ with printing type 2. The function block exclusively supports use as a pure room control unit; the internal PI controller (present depending on device type) is not used.\
Analog outputs AO1 and AO2 (if present)
The current states of the analog outputs (0.0 - 10.0 V) are determined either by the internal PI controller (eAnalogOutputsMode = AUTOMATIC_MODE) or by the inputs ‘rAO1Manual’ and ‘rAO2Manual’ (0.0 - 100.0%) (eAnalogOutputsMode = MANUAL_MODE).\
Display of symbols on the room control unit
Various symbols on the display of the room control unit can be shown via the associated inputs with the prefix ‘xDsplSymb_X’ (FALSE = off, TRUE = on). Update of date/time on the room control unit
On every rising edge at input ‘xUpdateDateTime’ the parameters with the prefix ‘wDateTime_X’ are transferred to the room control unit. The parameters are checked for adherence to the limits.\
Display of external measured values
Up to four different external measured values can be transmitted to the room control unit via the inputs ‘rExtValueX’ (X = 1 .. 4), multiplied by the respective parameter ‘rExtValueXMult’, and brought up for display (see configuration).\
Fan stages
The number of switchable fan stages is specified in the configuration (output ‘wNbrOfFanStages’). The current operating mode is shown at the output ‘eFanModeDev’. The fan stage is primarily set in night or day operation by the input ‘wAutoFanStages’ in the range 0 - ‘wNbrOfFanStages’. Manual correction (day operation only): With each pulse at the output ‘xButtonFanStages’ in day operation the fan stage is incrementally increased from the lower limit ‘wMinFanStageManDay’ up to the upper limit ‘wMaxFanStageManDay’, taking into account the output ‘wNbrOfFanStages’. On the next pulse it then switches back to the lower limit ‘wMinFanStageManDay’ before the sequence starts again. The manually specified fan stage in day operation is not retained when switching to night operation. Switching from manual correction to automatic mode occurs:\
when switching from night to day operation\
when switching from day to night operation\
if the button to change the fan stage (parameter ‘eButtonSelectionForFanStages’) on the RCU is pressed continuously for more than 3 s.\
if the button to switch to automatic mode ‘xVisuAutoFanStages’ was actuated
Mode (night and day operation)
The input ‘xMode’ is monitored for changes. On every rising edge the switch to day operation occurs, on every falling edge the switch to night operation occurs. The current mode is shown at the output ‘xModeDev’.\
Setpoints in the room control unit
The room control unit has two setpoints (1, 2) which can be displayed and used for temperature control. Each setpoint consists of a base value and an offset (effective setpoint = base value + offset). In this function block setpoint 1 is primarily used. The associated inputs and outputs are each labeled with the prefix ‘rSetpTempX’ (X = 1 .. 2). The outputs ‘rSetpTempXOffMaxFb’, ‘rSetpTempXOffMinFb’, ‘rSetpTempXStepFb’ and ‘rSetpTempXResetFb’ are read from the configuration and displayed. The current values on the RCU can be read at the outputs ‘rSetpTempX’ and ‘rSetpTempXOff’.\
Setpoint temperatures in day and night operation
On each transition to day operation the current setpoint temperatures 1 and 2 for day operation are transferred to the room control unit. On the first transition or after parameter changes the following is transmitted: Base value = ‘rSetpTempXBaseDay, offset = 0.0 On subsequent transitions the following is transmitted: Base value = last current base value, offset = last current offset On each transition to night operation the current setpoint temperatures 1 and 2 for night operation are transferred to the room control unit. Base value = ‘rSetpTempXNight, offset = 0.0\
Adjustment of setpoint temperatures in day operation
The parameter ‘eSetpTempOpMode’ specifies which setpoint the adjustment in day operation should affect. In day operation the current setpoint is increased by the step ‘rSetpTempXStepFb’ on every rising edge at the output ‘xButtonSetpTempUp’, provided the associated limit ‘rSetpTempXOffMaxFb’ has not yet been exceeded. In day operation the current setpoint is decreased by the step ‘rSetpTempXStepFb’ on every rising edge at the output ‘xButtonSetpTempDown’, provided the associated limit ‘rSetpTempXOffMinFb’ has not yet been undershot. Output ‘xButtonPresence’
A pulse of duration ‘tTimeButtonPulse’ is generated at this output if \
on the parameter ‘xVisuPresence’ OR\
on the output of the selected button ‘xButtonX’ (X = 1 .. 4) (selection via ‘eSelectButtonForPresence’)\
a rising edge is detected (= actuation). This output can be linked to the input ‘xButton’ of the function block ‘HVAC.Button1’ to realize occupancy time extension.\
Output ‘xButtonFanStages’
A pulse of duration ‘tTimeButtonPulse’ is generated at this output if \
on the parameter ‘xVisuFanStages’ OR\
on the output of the selected button ‘xButtonX’ (selection via ‘eSelectButtonForFanStages’)\
a rising edge is detected (= actuation). Manual correction (day operation only): With each pulse at the output ‘xButtonFanStages’ in day operation the fan stage is incrementally increased from the lower limit ‘wMinFanStageManDay’ up to the upper limit ‘wMaxFanStageManDay’, taking into account the output ‘wNbrOfFanStages’. On the next pulse it then switches back to the lower limit ‘wMinFanStageManDay’ before the sequence starts again. The manually specified fan stage in day operation is not retained when switching to night operation. Switching from manual correction to automatic mode occurs: 1) when switching from night to day operation 2) when switching from day to night operation 3) if the button to change the fan stage (parameter ‘eButtonSelectionForFanStages’) on the RCU is pressed continuously for more than 3 s. 4) if the button to switch to automatic mode ‘xVisuAutoFanStages’ was actuated\
Output ‘xButtonSetpTempUp’
A pulse of duration ‘tTimeButtonPulse’ is generated at this output if \
on the parameter ‘xVisuSetpTempUp’ OR\
on the output of the selected button ‘xButtonX’ (selection via ‘eSelectButtonForSetpTempUp’)\
a rising edge is detected (= actuation). Two operating modes are distinguished (parameter ‘eSetpTempOpMode’): 1) SETPOINT_1: on each pulse at output ‘xButtonSetpTempUp’ in day operation the adjustment of setpoint 1 is increased by the step for setpoint 1 2) SETPOINT_2: on each pulse at output ‘xButtonSetpTempUp’ in day operation the adjustment of setpoint 2 is increased by the step for setpoint 2\
Output ‘xButtonSetpTempDown’
A pulse of duration ‘tTimeButtonPulse’ is generated at this output if \
on the parameter ‘xVisuSetpTempDown’ OR\
on the output of the selected button ‘xButtonX’ (selection via ‘eSelectButtonForSetpTempDown’)\
a rising edge is detected (= actuation). Two operating modes are distinguished (parameter ‘eSetpTempOpMode’): 1) SETPOINT_1: on each pulse at output ‘xButtonSetpTempDown’ in day operation the adjustment of setpoint 1 is decreased by the step for setpoint 1 1) SETPOINT_2: on each pulse at output ‘xButtonSetpTempDown’ in day operation the adjustment of setpoint 2 is decreased by the step for setpoint 2\
Buttons 1 - 4 (button 1 = right, button 4 = left)
Each button can be assigned a defined function in the configuration, which is shown at the associated output ‘eFunctionButtonXFb’ (X = 1 .. 4). Independently, each actuation of button X is detected and represented at the output ‘xButtonX’ depending on the operating mode (parameter ‘eButtonXOutpMode’).\
'eButtonXOutpMode' = RAW: The output is active in parallel with the actuation of the button.\
'eButtonXOutpMode' = PULSE: At the output a pulse of duration ‘tTimeButtonPulse’ is generated for each new actuation of the button
Digital inputs 1 - 4 (depending on version)
Each digital input can be assigned a defined function in the configuration, which is represented at the associated output ‘eFunctionDIXFb’ (X = 1 .. 4). Independently, the current state of each input X is detected and shown at the output ‘xDIX’ (FALSE = open, TRUE = closed).\
Display of faults
Faults are indicated at the collective output ‘xAlarm’ (= TRUE). It includes communication faults (time delay: gc_Parameters.gc_tOnDelayxAlarmCom, default = 60s) and device faults (direct). At the output ‘eErrorCodeCom’ a descriptive text is available in case of a communication error. It always shows the cause of the last communication error.
