Process Safety
It is important to have good tightening programs or Psets with reasonable torque and angle limits.
Tightening's that finish quickly, also called "rehits", can be a source of errors in the process. In many cases these types of tightenings can be avoided by using a multistep Pset. If this is not possible and the quick tightening sequence causes problems, it can be necessary to add a short waiting step of approximately 0.8 - 1.6 s at the end of the Pset.
The Self-locking Function in the Controller
To ensure a safe process in all cases it can be necessary to enable a self-locking function in the controller. The self-lock will in most cases be much faster compared to ILG in locking the tool as no signal transmission is required. The self-locking function is supported with release 3.10.11+.
Configure the controller with the settings in Image 1.

This function is only supported with the Connection Types ASDK and ASDK remote.
Use internal batch control for Psets in the source with batch size = 1.
Configure the controller with the settings in Image 2.
Image 2.
Use external batch control and let ILG set the batch size = 1.
This requires message mapping in ILG, refer to the Message Mapper Page chapter.
Input Message: Release tool: Tool: default
Output Message: Advanced: drivers / tc_set_batch_size - {}.
Configure the controller with the settings in Image 3.

Configure the controller with the settings in Image 4.
This configuration makes sure that the tool is locked if ILG looses the connection with the controller.
