HMK_Basic_Ctrl

Overview

This function block configures the function for use with the HMK and is used to send out basic commands to control the LEDs on the device.

Inputs

Entering the HMK_Basic_Ctrl 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 Chkpt BOOL T/F --
CAN.Port PORT -- -- Determines which physical CAN port of the hardware to receive data from.
Loop_Tm U16 0 to 65535 ms Processing time of one program loop. Enable BOOL T/F --
Buttons BUS -- -- Contains control signals for the LEDs on the HMK. Button(1-8).

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. TxRate U16 100 to 65535 ms How often the message will be sent out.

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
Status U16 0, 0x8008 --
Fault U16 0, 0x8002 --
inputs, parameters, and output signals are contained inside of the bus. 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

Diagnostic Signals

Entering the Checkpoints page on the second level of the function block provides access to the block’s diagnostic signals. It contains checkpoints on 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
CAN_Send BOOL T/F --

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 > 253, TxRate
*
Bit 16 set to 1 identifies a standard Danfoss status or fault code.

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
*
Binary Cause Response Correction
0x8002 0010
<100
Fault Logic
The fault code indicates whether the inputs of the function are within their valid range.
Buttons.Button(1-8).Backlight_Color > 3 Buttons.Button(1-8).Indicator_Color > 3 Buttons.Button(1-8).LED_State > 3 Buttons.LED_Group > 3
Status Code, Transmission is disabled
Fault Code, Transmission is disabled
Correct Dest_Addr, or Src_Addr or TxRate value.
Correct out of range input value.

Instalation

Chkpt enables the checkpoints for each Diag Bus Signal. It is pre-connected to a constant True. It only
makes sense to set it to False if you don’t want to use the checkpoints or if you need to free up some memory. Be aware that Fault and Status signal will also disappear from the service screen by this action.

About the Namespace Feature

If you use this function block more than once in an application, you must change each function block’s Namespace value to avoid compiler errors.
This function block contains one or more components that allocate memory using memory names (“aliases”). Identical function blocks have identical memory names. Identical memory names cause compiler errors.
The Namespace value adds a unique prefix to each component name to avoid errors. Keep each Namespace value short to save controller memory.

How to Enter a Namespace Value

1. In the PLUS+1 GUIDE menu bar, click the Query/Change button.
2. Click the function block’s page name to display the Edit Page window.
3. In the Edit Page window, enter a meaningful Namespace value. Namespace values are case-sensitive.
4. Press the Enter key.
5. Repeat these steps to enter unique Namespace values for other identical function blocks.
