■Operation
The following remote registers (RWr/RWw) are used for the output time setting control.
• ON/OFF selection flag (RWw4, RWw5) ( Page 241 ON/OFF selection flag)
• Output time setting Y (RWw10 to RWw8F) ( Page 244 Output time setting)
The following figure shows the operation of output time setting control using the external output Y0.
• For the I/O module operating with the output time setting control, External output signal Y (RY0 to RYF,
RY10 to RY1F) becomes invalid.
• A change of the external output Y (status of the Y terminal) is sent to the connected device with delay of
the maximum output response time.
• Therefore, if the output is set to turn on or off at an interval shorter than the maximum output response time,
the actual output may not turn on or off.
• The resolution of output time setting control is 8ns.
• 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. The clock of the network differs from the clock of the CPU module.
Therefore, set a time to turn on or off the output based on the input change time.
Performed by the I/O module
The output turns on at DD:EE:FF.000, BB/CC/20AA.
The output turns off at DD:EE:FF.010, BB/CC/20AA.
(1) 1 (Turn on the output.)
(2) 0 (Turn off the output.)
