Chapter 1 Programming
1.4.4 Output Disabled Function
This function disables outputs from each unit in RUN mode without regard to the
program used. By disabling external outputs, the program can be debugged while
external equipment is connected, even when output of signals to the external
equipment is not desired.
■ Setting procedure
When special utility relay 2300 turns ON, all outputs from all output relays (0500 to
0915) to the outside are cleared after 1 scan is finished.
However, the display in the Access Window and the output indicator lamps are not
cleared.
■ Setting example
By setting/resetting special utility relay 2300 using the Access Window, the "KV
IncrediWare (DOS)" or "LADDER BUILDER for KV" programming support software,
or the KV-P3E(01) handheld programmer, the external output prohibition function
can be used.
External outputs are prohibited while input 0000 is ON. External outputs are permit-
ted, though, while input 0000 is OFF.
➮ For more about operating procedures, refer to the "Chapter 6. Handheld Programmer" (p.1-195).
1.4.5 Input Refresh Disabled Function
This function disables the update of inputs from each unit triggered by input signals
from external equipment.
By disabling external input refresh, inputs from each unit can be set to ON/OFF in
monitor status without mechanical operations to enable a program check.
■ Setting procedure
When special utility relay 2301 turns ON, input refresh (read of input relays) for all
input relays (0000 to 0415 used by the QL Series) is skipped.
In this status, inputs can be set to ON/OFF from the Access Window, the "KV
IncrediWare (DOS)" or "LADDER BUILDER for KV" programming support software,
or the KV-P3E(01) handheld programmer.
■ Setting example
By setting/resetting special utility relay 2301 using the Access Window, the "KV
IncrediWare (DOS)" or "LADDER BUILDER for KV" programming support software,
or the KV-P3E(01) handheld programmer, the external input refresh prohibition
function can be used.
External input refresh is prohibited while input 0000 is ON. External input refresh is
permitted, though, while input 0000 is OFF.
➮ For more about operating procedures, refer to the "Chapter 6. Handheld Programmer" (p.1-195).
Note: Once external input refresh is prohibited, it can be permitted only by setting
special utility relay 2301 to OFF from the Access Window, the "KV IncrediWare
(DOS)" or "LADDER BUILDER for KV" programming support software, or the KV-
P3E(01) handheld programmer.
