IORF(097) Refreshing
When IORF(097) (I/O REFRESH) is executed, the input bits in the specified range of words are refreshed. This
I/O refreshing is performed in addition to the normal I/O refreshing performed once each cycle.
In the following example, IORF(097) refreshes the I/O points in the four I/O Area words CIO 0000 to CIO 0003.
The status of inputs is read from the Input Units and the status of output bits is written to the Output Units.
In this case, the status of input points allocated to CIO 0000 and CIO 0001 are read from the Input Unit.
(CIO 0002 and CIO 0003 are allocated to Output Units.)
Limitations on Input bits
There is no limit on the number of times that input bits can be used as normally open and normally closed con-
ditions in the program and the addresses can be programmed in any order.
An input bit cannot be used as an operand in an Output instruction.
Input Response Time Settings
The input response times for each Input Unit can be set in the System Setup. Increasing the input response
time will reduce chattering and the effects of noise. Decreasing the input response time allows higher speed
input pulses to be received. (The input’s ON time and OFF time must be longer than the cycle time.)
The default value for input response times is 8 ms and the setting range is 0 ms to 32 ms.
Note If the time is set to 0 ms, there will still be an ON delay time of 20 s max. and an OFF delay time of
370

300 s due to delays caused by internal elements.
