Port drop down lists available ports. However, some of the ports may be used by other
devices (modem, mouse, etc.). Select Disabled to prevent I/O from using the PLC.
Period: Sets the measurement period between .2 seconds (5 readings per second) and
2 seconds. A longer period gives higher reading accuracy, especially at low rates.

response to process changes, high settings give smoother graphs.
