Program Debugging

At a Glance

After transferring the program and running the axis using Powersuite for Lexium 05, the process is commissioned.

An animation table is a commissioning solution used to monitor, modify and/or force the values of variables.

The sets of parameters of the axis may be accessed and modified in Control Expert using the MFB messaging blocks MC_READPARAMETER and MC_WRITEPARAMETER.

Modification Mode

The following screen shows the animation table in modification mode:

This table is used to determine the status of the MC_POWER block’s input and output parameters.

To access this mode, click on the Modify button in the mode selection zone.

NOTE: this operation may be assigned to other function blocks.

NOTE: the animation table is dynamic only in online mode (display of variable values).

Modifying Values

The tutorial example uses Boolean variables. To modify a Boolean value, carry out the following actions:

Step	Action
1	Use the mouse to select the Boolean variable you wish to modify.
2	Click on the button corresponding to the desired value, or execute the Set to 0 or Set to 1 commands in the contextual menu.

Starting the System

The following table describes the procedure for starting the system used in the example:

Step	Action
1	Set the variable Cmd_Run_Z to 1. Result: the variable Axis_OK_Z changes to 1.
2	Set the variable Cmd_Reset_Z to 1.
3	Set the variable Cmd_Home_Z to 1. Result: the axis is referenced.
4	To rotate the axis, set the variable Cmd_Mvt_Z to 1. Result: the axis starts to turn and the values of the variables Position_Z and Velocity_Z are no longer set to 0.
5	To stop the axis from rotating: set the variable Cmd_Stop_Z to 1 set the variable Cmd_Mvt_Z to 0 Result : the axis stops rotating.
6	To start to rotate the axis again and complete the movement: set the variable Cmd_Stop_Z to 0 set the variable Cmd_Mvt_Z to 1 Result: the axis starts to rotate again and completes its movement.
