1
To enable Programmer function, go to GENERAL screen of PMC
Settings, and choose ”YES” at item ”PROGRAMMER ENABLE”.
2
To deactivate Online Monitor function, go to ONLIEN screen of
PMC Settings, and choose ”NOT USE” at settings of ”RS–232C” and
”F–BUS” (if appears).
2. ”number” + INPUT key
When cursor is shown, you can force the value of the address
under cursor by entering new value as ”number” + INPUT key.
In this screen, Forced I/O function is limited only to Forcing
mode. This Forced I/O function asks you to confirm your
intention before it takes effect. Once it is confirmed that you
actually want to change value by this function, you can change
the value of the same relay or parameter without further
confirmation. However, after you move cursor or you operate
other functions, you will be asked when you use the Forced I/O
function again.
WARNING
1 You have to pay special attention to use Forced I/O function
to change status of signals. Inappropriate use of Forced I/O
function may cause unexpected reaction of machine. You
have to make it sure that nobody is near the machine
when you use this function.
2 As you use Forcing mode of Forced I/O function to change
status of signal, however, the signal may look proof against
Forced I/O function, because LADDER program or I/O
device writes into the signal repeatedly. In this case, even
if the signal looks unchanged, actual signal may be
changed in very short moment. You should be careful for
the reaction of machine to such signal changes.
NOTE
1 Forced I/O function is enabled when ”SIGNAL STATUS
WRITE ENABLE” setting is set to ”YES” in GENERAL
screen of PMC Settings. If the setting is ”NO”, INPUT key
will be just ignored.
2 Parameters of timer functional instructions, TMR, TMRB,
and TMRC, which have special monitor formats, are not
supported by Forced I/O function.
(c) Notes for Search function
1. The string followed by [SEARCH] is treated as symbol first. In
case that the symbol ”D0” is assigned to the bit address ”R0.0”,
the operation ”D0” + [SEARCH] will search the bit address
”R0.0”, instead of byte address ”D0”.
3
2. To search the symbol that consists of only digit characters, which
will usually be treated as net number, you can use leading space
to specify explicitly the string is symbol. For example, while
”123” + [SEARCH] will search the 123rd net from top of the
LADDER, ”_123” + [SEARCH] (”_” is space) will search
address with symbol ”123”.
