SIGNAL TRACE FUNCTION (PMC–SB7)
The signal trace function for PMC–SB7 has both the signal wave form
display function and the signal trace function for PMC–SA5/SB5/SB6
and has improved specification and operation.
PMC–SA5/SB5/SB6 PMC–SB7
Used condition The signal wave form display function
is provided in the ladder editing card.
Basic function as PMC control soft-
ware
Trace points 16 points 32 points
Sampling resolution 8ms (Fixed) 8ms to 1sec (Variable)
Maximum sampling time 10sec. (Fixed) Sampling time is expanded according
to number of trace points and resolu-
tion.
Ex.)
98sec. when 16 points and 8ms reso-
lution (Variable)
100 minutes when 32 points and 1
sec. resolution.
Display of trace result
Sampling graph does not be displayed
dynamically in signal wave form dis-
play function.
Sampling graph is displayed dynami-
cally during the execution of trace.
On/off status of each bit is displayed in
signal trace function
On the trace screen, you can trace specified signals. The result of the trace
is displayed as the time chart of signals. There are two tracing modes.
–”Time Cycle” mode: Samples the state of the signals at every
specified cycle time.
(Same specification as the signal wave
form display for PMC–SA5/SB5/SB6)
–”Signal Transition” mode: Samples the status of the signals when
the signals that are watched at every
specified time are changed.
(Same specification as the trace function
for PMC–SA5/SB5/SB6)
