menu with . As the access code is changed only the standard (low
level) items will be shown. To show the medium or high level menu
items the new access code has to be entered as described in the previous
example.
After the download of an application from TAC Menta, the access code
will
revert to the default value.
5.7 Overriding Inputs/Outputs
For access code high, it is possible to override the input and output val-
ues in the Status displays of the OP.
For example, to override a digital output you must indicate “manual
override” in the field just in front of the displayed value:
A2: Fan status
SF_out _0
With the cursor in the position just to the left of the 0 value, use
or twice to toggle up the manual override indicator (
→
).
Press to confirm and to move the cursor to the value itself. It is
now possible to change the value, a value that will override the value set
by the controller.
The override indicator will remain visible (for all access levels) until it
is reset to normal, automatic mode.
Network Variables (please refer to the TAC Menta User’s manual) can
also be overridden in this way.
5.8 Daylight Saving
TAC Xenta 280/300 has built-in support for the European standard day-
light saving. However, the OP can be used to set other conditions.
To change the Daylight saving period, the following menu is used.
