Note The Input and Output ON delay differs according to the Unit used.
The I/O response time is the time it takes from when an Input Unit’s input
turns ON, the data is recognized by the CPU Unit, and the user program is
executed, up to the time for the result to be output to an Output Unit’s output
terminals.
The length of the I/O response time depends on the following conditions.
The I/O response time is shortest when data is retrieved immediately before
I/O refresh of the CPU Unit.
The minimum I/O response time is the total of the Input ON delay, the cycle
time, and the Output ON delay.
The I/O response time is longest when data is retrieved immediately after I/O
refresh of the Input Unit.
The maximum I/O response time is the total of the Input ON delay, (the cycle

FALS errors are detected when the FALS instruction is executed, so no time is
required to detect the error. Only the operation switching time (0.5 ms) is required.
Time required by the CS1D to detect the long cycle time (depends on the setting of
the maximum cycle time) plus the operation switching time (0.5 ms).
Program error detection is performed constantly, so no time is required to detect
the error. Only the operation switching time (0.5 ms) is required.
Inner Board error detection is performed constantly, so no time is required to detect
the error. Only the operation switching time (0.5 ms) is required.
Memory error detection is performed constantly, so no time is required to detect the
error. Only the operation switching time (0.5 ms) is required.
