## Logical Device editors

The logical device functionality allows you to assign logical names to output registers on physical devices, and associate the generic inputs with standard measurements, including WAGES measurements.

Before you can create a logical device, the physical device that it references must be created in . You can create one or more logical devices from a single physical device, or you can also create a single logical device from several physical devices.

After you create a logical device, you can view its real-time data in the following components:

caution

inaccurate data results

Do not incorrectly configure logical devices; this can lead to inaccurate reports and/or data results.

Do not rely solely on reports to determine if the system is functioning correctly or meeting all applicable standards and compliances.

Do not use reports or data results as substitutes for proper workplace practices or equipment maintenance; they are supplemental only.

Failure to follow these instructions can result in injury or equipment damage.

Each logical device has a logical device type associated with it. Each logical device type is defined with a collection of output measurements. The measurements defined by the device type become the output measurements for instances of that device type, that is, for the logical devices. You use the to create logical device types. See "" on page 1 for information about viewing, creating, editing, and deleting logical device types.

The in allows you to configure specific logical devices by mapping input registers to output measurements that are defined in the associated device type. See "Logical Device Editor" on page 1 for information about creating, configuring, editing, and deleting logical devices.

### Access level for the editors

You need supervisor-level access to be able to define logical device types and to create logical devices in the editors.

See "" on page 1 for further information about creating users and groups, and for setting system access levels.
