QUALITY.MANUAL_MODE can be used as an attribute that references the QUALITY indicator called MANUAL_MODE.

QUALITY.MANUAL_MODE enables a user to take a device point that may or may not be currently available and put it in manual mode. The user can then set the point's value. This is particularly useful if a point is attached to equipment that is known to be malfunctioning and, as a result, creates a problem in other areas of the system. This indicator enables a user to separate the point from that equipment and set the point to a known good value that preserves the system's integrity.

Note:When a read-only device point is put in manual mode, the read-only feature is ignored. As a result, if Allow set point for read only manual mode  points is checked (enabled) in the Point Setup dialog box that is accessed through the Project Properties dialog box, administrators who are performing system diagnostics can change its value for testing purposes.


A temperature sensor that reports temperatures, which are acted upon by CIMPLICITY applications to initiate temperature control actions, fails. To continue the high temperature setting, a user with Modify attributes privilege places the point that reflects the errant sensor in manual override mode. The user then sets a value that causes the application to cease the unnecessary temperature control procedures. This allows users who are knowledgeable of their CIMPLICITY application implementation to make emergency, temporary adjustments to their system's operation. Consequently the application does not have to anticipate and provide for handling of all possible failures in its implementation.
