To
refresh I/O words allocated to Special I/O Units (IR 100 to IR 199), indicate the
unit
numbers of the Units by designating IR 040 to IR 049 (see note). IR 040 to
IR 049
correspond to Special I/O Units 0 to 9. For example, set St to IR
043 and E
to
IR 045 to refresh the I/O words allocated to Special I/O Units 3, 4, and 5. The
I/O words allocated to those Units (IR 130 to IR 159) will be refreshed when
IORF(97)
is executed.This will be in addition to the normal I/O refresh performed
during the CPU’s cycle.
Note I/O will not be refreshed if IORF(97) is executed for any of the following Units:
Group-2 High-density I/O Units
I/O
Units or
Special I/O Units mounted to Slave Racks (in Remote I/O Sys

tems)
Optical I/O Units (in Remote I/O Systems)

to

-
tails on refreshing words allocated to Group-2 High-density I/O Units.
Execution Time When
Basic I/O Units are specified, the execution time for IORF(97) is computed
as follows:
T
IORF
= instruction execution time + Input Unit I/O refresh time
+ Output Unit I/O refresh time
= 0.13 ms + 0.02 ms × (no. of 8-pt Units + no. of 16-pt Units × 2)
+
0.02 ms
×
(no. of 5- and 8-pt Units + no. of 12-/16-pt Units
×
2)
When
Special I/O Units are specified,
the execution time for IORF(97) is com
-
puted as follows:
T
IORF
= instruction
execution time +
(Special I/O Unit I/O refresh
times)
The
instruction execution time is 0.1 ms. Refer to

Limitations MPRF(61)
can be used to refresh I/O words allocated
to Group-2 High-density
I/O Units (IR 030 to IR 049) only. It cannot be used for other I/O words.
St
and E must be between #0000 and #0009. St must
be less than or equal to E.
Description When
the execution condition is OFF
,
MPRF(61) is not executed. When the ex
-
ecution condition is ON, the I/O words allocated to Group-2 High-density I/O
Units
with I/O numbers St through E will
be refreshed.This will be in addition to
the normal I/O refresh performed during the CPU’s cycle.
It
is not possible to specify the I/O words by address, only by the I/O number of
the Unit to which they are allocated.
Execution Time The execution time for MPRF(61) is computed as follows:
T
MPRF
= Instruction execution time
+ (Group-2 High-density I/O Unit I/O refresh times)
