HMK_Brightness

Inputs

Entering the HMK_Brightness function block gives an overview about the block’s signals.
To avoid compiler errors, use only the data types specified in this table.
Function Block Inputs
Input Type Range Unit Description CAN.Port PORT -- -- Determines which physical CAN port of the hardware to receive data from.
Red U16 0 to 10000 0.01%
Green U16 0 to 10000 0.01%
Blue U16 0 to 10000 0.01%
White U16 0 to 10000 0.01%
Send BOOL T/F --
This variable can be found in the CAN sub-bus if using the Main Template. Global brightness of RED Color.
0: No Change 1: Min Brightness … : 10000: Max Brightness
Global brightness of GREEN Color. 0: No Change 1: Min Brightness … : 10000: Max Brightness
Global brightness of BLUE Color. 0: No Change 1: Min Brightness … : 10000: Max Brightness
Global brightness of WHITE. 0: No Change 1: Min Brightness … : 10000: Max Brightness
False to true transition will send the specified command. T: Positive transition will send the command F: Do not send command

Parameters

Learn how the function block uses parameters to customize the function.
To avoid compiler errors, use only the data types specified in this table.
Function Block Parameters
Parameter Type Range Unit Description Src_Addr U8 0 to 253 -- Source Address of the local device.
Dest_Addr U8 0 to 253 -- Destination Address of the HMK.

Outputs

Learn how the outputs of the function block work.
Function Block Outputs
Parameter Type Range Unit Description OR BOOL T/F -- CAN Tx OverRun Flag.
Pend BOOL T/F -- CAN Tx Pending Flag. Diag BUS -- -- This bus provides diagnostic values for troubleshooting. In addition, all

Diagnostic Signals

The diagnostic bus contains signals for input, parameter, output, and internal signals. Only the internal signals are explained below. Input, parameter, and output signals are described in the above chapters.
Function Block Diagnostic Signals
Name Type Range Unit Description CAN_ID U32 -- -- The resulting 29-bit J1939 ID.
CAN_Data ARRAY[8
]U8
CAN_Send BOOL T/F --
-- -- Data that is to be sent over CAN.
This signal indicates if a parameter fault is declared. It’s a bitwise code, so multiple items can be reported at a time. The following status codes are provided: 0x0000: No fault 0x8008: At least one parameter is out of range
This signal indicates if an input fault is declared. It’s a bitwise code, so multiple items can be reported at a time. The following fault codes are provided: 0x0000: No fault 0x8002: An input value is too high
Pulses true when a message is being sent. T: Pulse triggered F: Idle

Status and Fault Logic

This topic describes how status and fault logic is indicated for the function block.

Status Logic

The status code indicates whether the parameters used in the function are within their valid range.
Status Logic
Condition Hex
Invalid Setup 0x8008 1000 Dest_Addr > 253, Src_Addr >
*
Bit 16 set to 1 identifies a standard Danfoss status or fault code.
*
Binary Cause Response Correction
253

Fault Logic

The fault code indicates whether the inputs of the function are within their valid range.
Fault Logic
Condition Hex
An input is too high
*
Bit 16 set to 1 identifies a standard Danfoss status or fault code.
*
Binary Cause Response Correction
0x8002 0010 Red > 10000, Green > 10000, Blue > 10000,
White > 10000
Status Code, Transmission is disabled
Fault Code, Transmission is disabled
Correct Dest_Addr or Src_Addr value.
Correct Red, Green,Blue, or White value.
