4.7 Overriding inputs/outputs

TAC AB, 2001-08-08
To change the code that gives the operator access to the medium or
high level items, the access level code for the level to be changed must
first be entered as described above. Then go to the Edit Access Code
screen:
A2: EDIT ACCESS CODE
EDIT CODE: 0000
Change code for
the active level (no.)
Use to move the cursor between the digits and use
to change their value. When finished, press
–
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.
For access code high, it is possible to override the input and output
values 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.
