Operation
The following remote registers (RWr/RWw) are used for the input time acquisition control.
• Input time information X
 (RWr10 to RWr8F) (

Page 238 Input time information)
• Input ON/OFF information (RWr4, RWr5) (

Page 234 Input ON/OFF information)
• ON/OFF selection flag (RWw4, RWw5) (

Page 241 ON/OFF selection flag)
Ex.
The following figure shows the operation of input time acquisition control using the external input X0.
• The operation of external input signal X  is the same both for the input time acquisition control and for the
synchronous X input control. Therefore, even when the I/O module is operating with the input time
acquisition control, a user can get the input status information of each synchronization cycle start timing by
referring to External input signal X
 (RX0 to RXF, RX10 to RX1F).
• The input change time is stored in Input time information X  (RWr10 to RWr8F) at the second
synchronization cycle after the input has changed.
• The resolution of input time acquisition control is 8ns.
• If a major or moderate error occurs in the I/O module, 0 is stored in Input time information X
 (RWr10 to
RWr8F).
• The input change time to be stored in the buffer memory area is based on the clock of the network where
the I/O module performs data link. Note that the clock of the network differs from the clock of the CPU
module.
