Show Terminals
Displays the terminal configuration display screen.
I/O Monitor
Displays the I/O monitor screen.
Check I/O Board
Displays the I/O board check execution screen.
Terminals
Displays configurations of the specified input terminals (X0 to X11) and output terminals (Y0 to Y5).
When the LT33** series is used, it displays the configuration of input terminals X0 to X15 and output terminals Y0 to Y15. The bottom of the screen shows [X8-X15: Std Input] and [Y4-Y15: Std Output].
The monitoring results of the standard input and output can be displayed by selecting either bit or integer. The [Word] display cannot be selected when special I/O is used.

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)
[Type] = [Bit]
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.
With the LT33** series, you can check the status by using inputs 0 through 15.
[Type] = [Word]
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)
[Type] = [Bit]
The terminal number specified for standard output is displayed. You can check the output value by bit.
With the LT33** series, you can check the status by using outputs 0 through 15.
[Type] = [Word]
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.
For details about error messages, refer to the following description.
Start
The system starts checking if the I/O board is operating normally or not. If the I/O board operation is abnormal, the corresponding error message appears.
