FUNCTIONS
(b) When only Device is specified:
Word Device or Bit Device can be specified.
1) When Word Device is selected:
The monitor data is sampled is when the current value of the specified word
device becomes the specified value.
Type a current value in decimal digits or hexadecimal digits.
2) When Bit Device is specified:
The monitor data is sampled is when the execution status of the specified bit
device becomes the specified value.
Either the leading edge or the fall can be specified for execution condition.
(c) When Step No. and Device is selected:
The monitor data is sampled when the status previous to execution of the
specified status or the status (current value) of the specified bit device (word
device) is specified.
POINT
When "Step No.[100]=<-P->, Word Device [D1]=[K5]" is specified as the detailed
condition in the following circuit, a monitor execution condition is established at
the leading edge of the Step 100 where D1=5.
Besides, the monitor interval of GX Developer depends on the processing speed
of GX Developer.
For the monitor execution conditions established at the interval shorter than the
monitor interval of GX Developer, monitor is executed only when the monitor
execution conditions are met at the monitor timing of GX Developer.
