Determines the mechanism used to transfer frames in this schedule entry (slot).

The default value is Unconditional (0).

Data type: datatype_icon

Long Name: Type

Class: XNET LIN Schedule Entry

Permissions: Read/Write

The values (enumeration) for this property are:

Enumeration Value Description
Unconditional 0 A single frame transfers in this entry (slot).
Sporadic 1 The master transmits in this slot. The master selects among multiple frames to transmit. Only updated frames are transmitted. When multiple frames have been updated, the master decides by priority; the other updated frames remain pending and can be sent when this schedule entry executes again. Order of frames in the Frames property determines frame priority.
Event-triggered 2 Multiple slaves can transmit a frame in this slot. When a collision occurs, this is detected and resolved using a schedule specified in the Collision Resolving Schedule property.
Node configuration 3 Schedule entry contains a node configuration service. The node configuration service is defined as raw data bytes in the Node Configuration:Free Format:Data Bytes property.

A LIN frame can exist in multiple schedules and multiple schedule entries. For example, if a frame exists in an Event-triggered entry in schedule A, it also exists in an Unconditional entry of a different schedule B, so that Event-triggered collisions in schedule A can be resolved by switching to schedule B.
