GuardLogix® Tools
GuardLogix Estimator
The second tool, the GuardLogix Safety Estimator was based on the initial calculator and was expanded to provide a
more intuitive interface through a wizard. This tool also provides multiple network functionality within the application,
adding Ethernet communication to the original DeviceNet-only implementation.
Safety reaction-time performance is based on how the safety task is configured in the GuardLogix controller, and the
settings for the safety I/O modules used in the GuardLogix project. The wizard interface in the GuardLogix Estimator
lets you move forward or backward to change values and evaluate how those changes impact system behavior.
