7.1.2 Forced I/O Screen
On the forced I/O screen, the value of an arbitrary signal can be
modified forcibly.
The forced I/O screen can be used in one of two input modes: the
forced I/O mode and the override mode. To move to the forced I/O
screen, press the [FORCE] soft key on the SIGNAL STATUS screen.
On the forced I/O screen, the following operations can be performed:
· Signal search [SEARCH]
· Switching to display/input in decimal [DEC]
· Switching to display/input in hexadecimal [HEX]
· Transition to the SIGNAL STATUS screen [EXIT]
· Signal on [ON]
· Signal off [OFF]
· Override setting [OVRIDE SET]
· Override cancellation [OVRIDE RESET]
· Complete override cancellation [INIT]
In the input mode display area to the right of the title, "OVERRIDE"
is displayed only when the forced I/O mode is set to the override
mode.
The signal status display area indicates the signal status of each
address. The status shown below is indicated for X and Y signal bits
for which override is set.
