Block
Mask
Description
- The blocks OpAsync_429_Scheduled_Send and OpAsync_429_Scheduled_MajorFrame are used to define the periodic scheduled transmission.
- The blockOpAsync_429_Scheduled_MajorFrame defines the major frame parameters. It defines the period and the channel of scheduled messages.
- The OpAsync_429_Scheduled_Send blocks define the minor frame parameters. It defines the messages with its scheduled time execution.
- Several OpAsync_429_Scheduled_Send blocks could be attached to one major frame to describe the content of the message and its sending time.
Parameters
Send ID | Each OpAsync 429 Send block is assigned a unique Send ID to be distinguished among multiple send blocks. |
---|---|
Major Frame ID | Each OpAsync_429_Scheduled_MajorFrame block is assigned a unique ID to be distinguished among multiple MajorFrame blocks. |
Controller ID | Specifies the controller ID that will be associated with each OpAsync 429 Send and OpAsync 429Recv blocks. |
Sub-device number | OneARINC 429 board can contain more than one independent ARINC 429 capable device. This parameter specifies which sub-device is to be used by the current block. The availability of the sub-devices depends on the ARINC 429 board model that is used. |
Channel Number | This parameter corresponds to the number of the channel that is to be used on the selected sub-device. It is important to note that, on a given sub-device, the reception channels must precede the transmission channels and that no channels may be used in both transmission and reception modes. This value ranges from 1 to 8. |
Transmit Speed | Select the transmission speed between 12.5k bps and 100k bps. |
Minor Frame Count | Specifies the number of desired minor frames. |
Minor Frame Time (µs) | Specifies the time in microseconds allotted for a minor frame. Note: 'Minor Frame Time * MinorFrame Count' gives the period of the major frame. |
