Evaluation
Signals with various pulse widths (every 5 msec) were input to the standard
I/O input and the input module of the fieldbus I/O at 1 Hz. For 10 minutes
(600 seconds), pulse widths of the received signals were measured at 12
Mbps and 9.6 kbps.
Result
12 Mbps: The input devices responded to 25-msec pulse.
9.6 kbps: The input devices responded to 80-msec pulse.
