FramePosCmd
16-bit data source (
positionReq
) is set only manually, by
means of the
positionReqManual
box.
7.4.3 Status Notes and State Buttons
On the yellow background can be seen two Status notes and three State
buttons:
•
Status - displays current status of LIN communication and can be:
–
Idle - LIN is activated, but communication is not started
–
Run - communication is running
–
Sleep - LIN-bus is in Sleep state
•
Error - global error label, which accumulates all error warnings.
•
Sleep/Wake up - sends sleep or wake-up frame.

variable of both loops
forced to zero and the mode of Loop1 is set to Manual.
7.4.4 Error Handling
The Error notes can be:
•
None - communication without errors
•
No Response - Slave is not responding (wrong selected Axis or
Slave is missing). In case, when is Slave responding, this note
reflects checksum error.
•
Transmitter Issue - more than one LIN device is transmitting or LIN
SIO wire is shorted to the supply source wires.
7.4.5 Low Time Cases
If the time dedicated to Loop1 communication requests is always shorter
than the time necessary for Loop2 communication, the priority rule of
Loop1 is dismissed and loop requests are satisfied in order following
each other. This state is signalled by the note
