a response of "<(6" results in an appropriate message on the display. Acknowledge
the message by pressing the
Manual overwriting is cancelled if the process is restricted because, for example,
"LQSXW LJQRUHG" is not set (see Sub-section 7.4.3). Manual overwriting is also
canceled if the user aborts the procedure. The display provides an appropriate
message if manual overwriting is canceled. Acknowledge the message by pressing

For safety reasons, manual overwriting can only be executed locally using the keypad
on the front panel of the device. The feature is not available in DIGSI
A feature of the 7SA6 that is especially useful during testing and commissioning of the
device is the capability of temporarily removing the coupling between a switching
device and the 7SA6, or between the SCADA and the 7SA6, without physically
disconnecting the equipment. This type of separation is also necessary, for instance,
if a switch position feedback message is not functioning properly (refer to Sub-section
7.4.2). The menu item 6(7 67$786 is used to perform the decoupling.
The menu displays a list of all planned switching devices and associated status
information identified by a letter. The letters have the following meanings:
• T Device is tagged (manually overwritten).
• I Input ignored, which means the acquisition of an input status is de-coupled from
the process (from the switch-gear).
• B Blocked, which means data transmissions to the central device (or
SCADASCADA) are blocked.
• C Chatter block active, which means, because of frequent message changes, the
chatter block was set.
• O Output block active, which means the command output is de-coupled from the
process (from the system).
• – None of the listed limitations is in effect.
Note:
Input ignored (I) only works for physical inputs! Do not set "input ignored" for
indications created by CFC and allocated to the operating level "Manual Overwriting".
Different to physical inputs - they do not provoke decoupling from the system.
With a device ready for operation, first press the
