Remarks

SEL Fast Message command frames are designed only to be sent to a device, not received from a device. As a result this frame does not implement ISupportFrameImage for automated frame parsing. This class exposes a constructor that accepts a binary image in order to manually parse a command frame.

Constructors

CommandFrame(DeviceCommand, MessagePeriod)	Creates a new CommandFrame from specified parameters.
CommandFrame(SerializationInfo, StreamingContext)	Creates a new CommandFrame from serialization parameters.
CommandFrame(Byte, Int32, Int32)	Creates a new CommandFrame from the given buffer.

Properties

AllowQueuedPublication	Gets flag that determines if frame image can be queued for publication or should be processed immediately. (Inherited from ChannelFrameBaseT)
Attributes	DictionaryTKey, TValue of string based property names and values for the DataFrame object. (Overrides CommandFrameBaseAttributes)
BinaryImage	Gets the binary image of this ChannelFrameBaseT. (Inherited from ChannelFrameBaseT)
BinaryLength	Gets the length of the BinaryImage. (Inherited from ChannelFrameBaseT)
BodyImage	Gets the binary body image of this CommandFrame. (Overrides CommandFrameBaseBodyImage)
BodyLength	Gets the length of the BodyImage. (Overrides CommandFrameBaseBodyLength)
Cells	Gets reference to the CommandCellCollection for this CommandFrameBase. (Inherited from CommandFrameBase)
Checksum	Gets calculated checksum for this ChannelFrameBaseT. (Inherited from ChannelFrameBaseT)
Command	Gets or sets the DeviceCommand for this CommandFrame.
CreatedTimestamp	Gets timestamp, in ticks, of when this ChannelFrameBaseT was created. (Inherited from ChannelFrameBaseT)
ExtendedData	Gets or sets extended binary image data for this CommandFrameBase. (Inherited from CommandFrameBase)
FooterImage	Gets the binary footer image of the BinaryImageBase object. (Inherited from ChannelBase)
FooterLength	Gets the length of the footer portion of the BinaryImageBase object. (Inherited from BinaryImageBase)

Measurements	Keyed measurements in this ChannelFrameBaseT. (Inherited from ChannelFrameBaseT)
MessagePeriod	Gets or sets the desired message period for the SEL device.
ParsedBinaryLength	Gets the parsed binary length derived from the parsing state, if any. (Inherited from ChannelFrameBaseT)
Published	Gets or sets published state of this ChannelFrameBaseT. (Inherited from ChannelFrameBaseT)
SortedMeasurements	Gets or sets total number of measurements that have been sorted into this ChannelFrameBaseT. (Inherited from ChannelFrameBaseT)
Source	Gets or sets the data source identifier for this ChannelFrameBaseT. (Inherited from ChannelFrameBaseT)
State	Gets or sets the parsing state for the this CommandFrameBase. (Inherited from CommandFrameBase)
Tag	Gets or sets a user definable reference to an object associated with this ChannelBase object. (Inherited from ChannelBase)
Timestamp	Gets or sets exact timestamp, in ticks, of the data represented by this ChannelFrameBaseT. (Inherited from ChannelFrameBaseT)
