Numeric Display (Dynamic)

Operator Menu Location: Generic Hardware Operators -> Dynamic Config Hardware

Operator Bitmap:

Functional Description:
This operator accepts structure compositions as inputs, and outputs a structure to configure it's operation. It must be linked to a hardware resource to complete its functionality.
Pin x accepts an input structure which configures the visual characteristics for the data to be displayed. Refer to the Configuration Inputs section of the table below for the structure components and the accepted values.

Pin x accepts a boolean input which indicates when to activate the display, on a signal's rising or falling edge.
Pin x 3 accepts an input structure containing the data to display and specification for whether the output is to blink. Refer to the Data Inputs section of the table below for the structure components and the accepted values.

Pin y outputs a structure containing status information. Refer to the Data Outputs section of the table below for the structure components and the expected values.

Configuration Inputs
ID	Type	Name	Relevant Modes	Comments / Notes
1	int8	Display Mode	All	0 = Disabled / Off 1 = Standard Numeric
2	int8	Decimal Point Position	All	0 = Floating Decimal Point 1 = Decimal Point after 1st Digit 2 = Decimal Point after 2nd Digit 3 = Decimal Point after 3rd Digit 4 = Decimal Point after 4th Digit 5 = No Decimal Point
3	int8	Brightness	All	Range [0-15]. 15 = Maximum Brightness.
4	int32	Refresh Delay	All	Refresh delay, in ms. (Typically 500ms)
5	bool	Pad Leading Zeros	All	0 = No padding 1 = Leading zeros are padded
6	float	Reserved1	All	This member is reserved for future expansion. To ensure compatibility with future Fairmount Automation software, this member should be set to zero (0.0).

Data Inputs
ID	Type	Name	Relevant Modes	Comments / Notes
1	float	Value To Display	All
2	bool	Blink Enable	All
3	float	Reserved1	All	This member is reserved for future expansion. To ensure compatibility with future Fairmount Automation software, this member should be set to zero (0.0).

Data Outputs
ID	Type	Name	Relevant Modes	Comments / Notes
1	int8	Status Code	All	Basic status information for the hardware. See "Status Codes" table on "Defines" worksheet.
2	int8	Mode	All	The display mode is echoed back to the data output block. This is intended mainly for networked operation, allowing the receiver to verify that the input is in the expected mode before interpreting data. Also useful when transitioning from one mode to another.
3	float	Reserved1	All	This member is reserved for future expansion. Until its meaning is defined by Fairmount Automation, applications should assume that its value is undefined.

User-Defined Properties:
Object Name. A string label that identifies the operator

Enable On. Defines at what segment of a signal the input should be read or indicates it is always active.

Comments: The following table defines the status codes in the Data Output structure:

Status Codes for Dynamic Configuration Generic Hardware Operators
Value	Name	Description
0	DYN_HW_STATUS_OK	Operator is behaving normally. No errors. Readings are safe to use.
1	DYN_HW_STATUS_CIRCUIT_WARNING	A fault has been detected in the circuit. For inputs, this may indicate an out-of-range reading. For outputs, this may indicate an overload condition. Readings returned (if any) may be "failsafe" values.
2	DYN_HW_STATUS_INITIALIZING	The hardware is initializing, and has not yet acquired valid readings. This can happen after the configuration has changed.
3	DYN_HW_STATUS_DISABLED	The hardware is set to an inactive mode, or has not yet been configured. Readings not valid.
4	DYN_HW_STATUS_USUPPORTED_CONFIG	The requested hardware configuration is unknown or is not supported by this hardware. Readings not valid.
5	DYN_HW_STATUS_RESOURCE_IN_USE	Some or all of the resources needed for the requested HW configuration are in use by other operators. Note: Certain HW modes require resources from multiple inputs or outputs. For example, PCM-1 Quad Decode and Event Timer modes require resources from both Digital Input 1 and 2. To use one of these two modes on the PCM-1, the other input must be in the "Disabled / Off" mode. Future Fairmount products may have similar "shared resource" limitations.
6	DYN_HW_STATUS_HW_FAULT	A major fault has been detected with the hardware resource. Readings not valid.
