Control Computer Access in the Machines Grid
The Machines grid shows all the machines (computers) that connected to the Calibration Control database and the number of times they connected.
The only fields that can change in the Edit dialog are the ‘Is Blocked’ checkbox and the Notes field. The purpose of the ‘Is Blocked’ checkbox is to remove machines from the license count by blocking those machines from using the software.
