Access control

In many cases, we have a data acquisition system that can be accessed by multiple users. Typically, we want each user to have specific permissions based on their role. For instance, an admin user should be able to configure the device and modify all its settings. A guest user might only need read-only access, while a calibrator user should be able to adjust calibration factors on the device. The openDAQ Access Control system makes this possible.

In an openDAQ device implementation, it is possible to define a list of users that can access it. Each user is a member of one or more user groups. When connecting to a device, it is possible to authenticate as one of the defined users. Access to various device components is restricted based on the user’s group membership.
