I/O Area
IORF(097) Refreshing
Limitations on Input bits
Input Response Time
Settings
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.
The following IORF(097) instruction refreshes the status of all I/O points in I/O
Area words CIO 0000 to CIO 0003. The status of input points is read from the
Input Units and the status of output bits is written to the Output Units.
In the following example, 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.)
There is no limit on the number of times that input bits can be used as nor-
mally open and normally closed conditions 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.
The input response times for each Input Unit can be set in the PLC Setup.
Increasing the input response time will reduce chattering and the effects of
noise and decreasing the input response time allows higher speed input
pulses to be received.
