7.4 Structure and function of the operating menu
The differences between the structure of the operating menus of the local display and the
Endress+Hauser FieldCare or DeviceCare operating tools can be summarized as follows:
The local display is suitable for configuring simple applications.
The operating tools (FieldCare, DeviceCare, SmartBlue, AMS, PDM, ...) can be used to
configure the parameters of wide-ranging applications.
Wizards help the user to commission the various applications. The user is guided through
the individual configuration steps.
7.4.1 User roles and related access authorization
The two user roles Operator and Maintenance (as-delivered state) have different write
access to the parameters if a device-specific access code has been defined. This access code
protects the device configuration from unauthorized access.
If an incorrect access code is entered, the user obtains the access rights of the Operator
role.
7.5 Access to the operating menu via the local display
7.5.1 Device display (optional)
Possible to operate the optical operating keys through the cover. No need to open the
device.
Functions:
• Display of measured values and fault and notice messages
• Background lighting, which switches from green to red in the event of an error
• The device display can be removed for easier operation
Backlighting is switched on or off depending on the supply voltage and the current
consumption.
The device display is also optionally available with Bluetooth® wireless technology.
