Programming Example Section 7-4
7-4-6 Test Run in MONITOR Mode
Switch the CQM1H in MONITOR mode and check the operation of the pro-
gram.
1,2,3... 1. Set the Programming Console’s mode switch to MONITOR mode.
2. Press the CLR Key to bring up the initial display.
3. Force-set the start input bit (IR 00000) from the Programming Console to
start the program.
The cursor in the lower left corner of the display indicates that the force set
is in progress. The bit will remain ON as long as the Set Key is held down.
4. The output indicator for output IR 01000 will flash ten times if the program
is operating correctly. The indicator should go OFF after ten one-second
flashes.
There is a mistake in the program if the output indicator doesn’t flash. In
this case, check the program and force set/reset bits to check operation.
C COIL DUPL The same bit is being controlled (i.e., turned ON and/or
OFF) by more than one instruction (e.g., OUT, OUT NOT,
DIFU(13), DIFD(14), KEEP(11), SFT(10)). or the same
timer or counter number has been used more than once.
Although controlling bit status from more than one
instruction is allowed for certain instructions, check
instruction requirements to confirm that the program is
correct or rewrite the program so that each bit is controlled
by only one instruction.
JMP UNDEFD JME(05) has been used with no JMP(04) with the same
jump number. Add a JMP(04) with the same number or
delete the JME(05) that is not being used.
SBS UNDEFD A subroutine exists that is not called by SBS(91). Program
a subroutine call in the proper place, or delete the
subroutine if it is not required.
