■Input signal status in the hardware logic (High/Low)
The input signal status (High/Low) in the hardware logic is determined depending on the input signals (ON/OFF) from external
devices and logical selection.
*1 Set the logic selection with the parameters of the external input block. For details, refer to the following.
Page 106 External input block
*2 The input signal status in the hardware logic is described as High and Low. For details, refer to the following.
Page 104 Signal status name
■Status of an output signal to external devices (ON/OFF)
The status of an output signal to external devices (ON/OFF) is determined depending on the status of Input terminal of the
external output block (High/Low) and logic selection.
*1 Set the logic selection with the parameters of the external output block. For details, refer to the following.
