Purpose

Updates the ECU with the current state of the calibration session (CCP only).

Format

Input

ECU ref in is the task reference which links to the selected ECU. This reference is originally returned from MC ECU Open.vi or MC ECU Select.vi, and then wired through subsequent VIs.
Session status is the new status to be set in the ECU.
Error in is a cluster which describes error conditions occurring before the VI executes. If an error has already occurred, the VI returns the value of the error in cluster to error out.
status is TRUE if an error occurred. This VI is not executed when status is TRUE.
code is the error code number identifying an error. A value of 0 means success. A negative value means error: VI did not execute the intended operation. A positive value means warning: VI executed intended operation, but an informational warning is returned. For a description of the code, wire the error cluster to a LabVIEW error-handling VI, such as the Simple Error Handler.
source identifies the VI where the error occurred.

Output

ECU ref out is the same as ECU ref in. Wire the task reference to subsequent VIs for this task.
Error out describes error conditions. If the Error in cluster indicated an error, the Error out cluster contains the same information. Otherwise, Error out describes the error status of this VI.
status is TRUE if an error occurred.
code is the error code number identifying an error. A value of 0 means success. A negative value means error: VI did not execute the intended operation. A positive value means warning: VI executed intended operation, but an informational warning is returned. For a description of the code, wire the error cluster to a LabVIEW error-handling VI, such as the Simple Error Handler.
source identifies the VI where the error occurred.

Description

This VI implements the CCP SET_S_STATUS command and is used to keep the ECU informed about the current state of the calibration session. The session status bits of an ECU can be read and written. Possible conditions are: reset on power-up, session log-off, and in applicable error conditions. The calibration session status is organized as a bit mask with the following assignment.

Bit Mask Assignment for Calibration Session Status

Bit Name Description
0 CAL Calibration data initialized.
1 DAQ DAQ list(s) initialized.
2 RESUME Request to save DAQ set-up during shutdown in CCP slave. CCP slave automatically restarts DAQ after start-up.
3 Reserved N/A
4 Reserved N/A
5 Reserved N/A
6 STORE Request to save calibration data during shut-down in CCP slave.
7 RUN Session in progress.
