  • SA: Source address
    Range: 0…0xFFFF
  • OpType: Operation type
    Range: 0…0xF
  • PIndex: PIndex is a node-based counter (1 byte) which increments per message sent. All low-level retries of a message have the same PIndex.
    Range: 0..0xFF
    Access: read only, Spy
  • MsgChannel: Transmission channel
    Range: 1…16
  • MsgOrigTime: Unsynchronized hardware time stamp (unit: 10 µs)
    Access: read only

    Range: 0, 1
    Access: read only
  • Most_RType: Message types:
    When receiving always Normal, other message types are received with mostRawMessage.
    When applying a mostMessage variable the type can be set to Normal, RemRead, RemWrite, Alloc, Dealloc or GetSource.
    Range: 0…0x5
  • Most_State: Status information
    Range: 0…0xFF
    Access: read only
  • Most_TelID: TelID
    Range: 0…0xF
  • Time: Synchronized time (unit: 10 µs)
    Access: read only
These selectors are only valid for mostAMSMessage
  • BYTE(idx): Provides access to the data bytes of the complex MOST message. (BYTE(0) is the first parameter byte)
    Range: 0 ≤ idx ≤ 65534
    Valid Values: 0..0xFF
  • DLC: Data length code (Number of user data bytes for mostAMSMessages)
    Range: 0..65535
These selectors are only valid for mostMessage
  • Arbitration: Bus arbitration bytes
    Range: 0…0xFFFFFFFF
    Access: read only, Spy
  • BYTE(idx): Provides access to the data bytes of the MOST frame. (BYTE(0) is the first byte behind the TelLen)
    Range: 0 ≤ idx ≤ 11
    Valid Values: 0…0xFF
  • CAck: Returns the CRC acknowledge code
    Range: 0…0xFF
    Access: read only, Spy, MOST150 only
    Values: 0x00: No Response, 0x01: CRC error, 0x04: OK
  • DLC: Data length code (TelLen)
    Range: 0…45

    Range: 0…0xF
  • MsgCRC: CRC code
    Range: 0…0xFFFF
    Access: read only, Spy
  • Most_RType: Message types:
    When receiving always Normal, other message types are received with mostRawMessage.
    When applying a mostMessage variable the type can be set to Normal, RemRead, RemWrite, Alloc, Dealloc or GetSource.
    Range: 0…0x5
    Access: MOST25 only
  • PAck: Returns the preemptive acknowledge code
    Range: 0…0xFF
    Access: read only, Spy, MOST150 only
    Values: 0x00: No Response, 0x01: Buffer full, 0x04: OK
  • PIndex: PIndex is a node-based counter (1 byte) which increments per message sent. All low-level retries of a message have the same PIndex.
    Range: 0..0xFF
    Access: read only, Spy, MOST150 only
Example:
Press <Ctrl>+<W> or select Signal insertion from MOST function catalog… from the shortcut menu to open a selection dialog listing all messages and their parameters from the function catalog for selection.
This includes all non-nested parameters in the user data with constant width and constant position.
In this context, the parameter name is inserted into the program text as a selector.
