2. Word Operand
In the following example, CIO 000201 is allocated to an actuator, an external
device connected to the output terminal of an Output Unit. The ON/OFF sta-
tus of CIO 000201 is output to the actuator just after !OUT 000201 is exe-
cuted.
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 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 this example, 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.)
Output bits can be programmed in any order. Output bits can be used as oper-
ands in Input instructions and there is no limit on the number of times that an
output bit is used as a normally open and normally closed condition.
Just after the instruction is executed, the ON/OFF status of the 16 I/O
points allocated to the specified word will be output to the output device(s).
