5.8 Optimisation of the cycle time

When FB DRIVE is activated, the PLC cycle is always under load, even if no parameter communication

takes place. Since several parameters are checked when FB DRIVE is called, programming errors can

be detected and the corresponding error messages can be indicated. However, the checking costs

computing time.

To sa ve computing time, you can operate FB DRIVE in ”expert mode”. This reduces the required

computing time by approx. 50 %.

Proceed as follows to activate the expert mode for FB DRIVE

OpentheinstancedatablockandsetthevariableXpertMode to TRUE:

Note!

When the expert mode is activated, FB DRIVE no longer checks the transferred parameters!

Therefore, the expert mode should only be activated if you are sure that the transferred parameters

are correct.

Tip!

If you have created a program which uses an older version of FB 90, STEP7 will indicate different time

stamps for FB 90 and the corresponding instance data block.

If so, change to the IL editor and create a new STEP7 instance data block. Then you can use the expert

mode.
