B-4-2
A bit in the I/O Area is called an output bit when it is allocated to a Basic Output Unit. The ON/OFF status of
output bits are output to devices such as actuators. There are two ways for the status of output bits to be
refreshed to an Output Unit: normal I/O refreshing and IORF(097) refreshing.
Normal I/O Refreshing
The ON/OFF status of output bits is output to external devices once each cycle after the entire program is exe-
cuted. The status is not output at other times.
In the following example, CIO 0002.01 is allocated to an actuator, an external device connected to an output
terminal of an Output Unit. The ON/OFF status of CIO 0002.01 is output to that actuator once each cycle.
IORF(097) Refreshing
When IORF(097) (I/O REFRESH) is executed, the ON/OFF status of output bits in the specified range of words
is output to their external devices. This I/O refreshing is performed in addition to the normal I/O refreshing per-
formed once each cycle.
In the following example, IORF(097) 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 this case, the status of input points allocated to CIO 0002 and CIO 0003 are output to the Output Unit.
(CIO 0000 and CIO 0001 are allocated to Input Units.)
