[Word] when using
special I/O.
Details
The following details setting screen appears.
On the details setting screen, specify an input filter time in
the range of 0 to 40. The input filter eliminates noise from an
input signal. An input signal that does not reach the time duration
specified here will not work. The system samples data at 0.5 ms
intervals and stores the data internally, to verify the data by
reading the input terminal status before the specified time at an
I/O refresh interval of 2 ms. If the input terminal is always in
the same state, this state is regarded as the value for the input
terminal. If it is not in the same state, the previous value is
regarded as the input value.
Input (0 to
11)
The terminal number specified for standard
input is displayed. You can check the input value by bit. When the
switch is not pressed, the OFF value is displayed. When the switch
is pressed, the ON value is displayed.
You can check the input value with integers 0
to 4095 when the LT32** series is used, or with integers 0 to 65535
when the LT33** series is used.
Output (0 to
5)
The terminal number specified for standard
output is displayed. You can check the output value by bit.
You can check the output value with integers
0 to 63 when the LT32** series is used, or with integers 0 to 65535
when the LT33** series is used.
Error display
If the I/O driver detects an error, the corresponding error code
and error message are displayed.
