I/O refreshing with the Special I/O Unit can be disabled. When cyclic refresh-
ing has been disabled, the Special I/O Unit’s data can be refreshed during
program execution with IORF(097).
1. Always disable a Special I/O Unit’s cyclic refreshing if the Unit’s I/O will be
2. Whenever disabling a Special I/O Unit’s cyclic refreshing, be sure that the
Data can be exchanged between CPU Bus Units and the CPU Unit through
the CPU Bus Unit Area, the DM Area, or FINS commands.
Data is exchanged each cycle during I/O refreshing of the CPU Bus Unit Area.
Basically, 25 words are allocated to each CPU Bus Unit based on its unit num-
ber setting. The number of words actually used by the CPU Bus Unit varies.
The Special I/O Unit Area ranges from CIO 1500 to CIO 1899 (25 words
Units).
Each CPU Bus Unit is allocated 100 words in the DM Area in the range of
D30000 to D31599 (100 words
may be transferred through the words allocated to each Unit. The timing of
data transfers depends on the model being used.
1. Data transferred when the PLC is turned ON.
2. Data transferred each cycle.
3. Data transferred when necessary.
refreshed in an interrupt task with IORF(097). An interrupt task error
(A40213) will occur if cyclic refreshing and IORF(097) refreshing are per-
formed simultaneously.
I/O for that Unit is refreshed with IORF(097) in the program at least every
11 seconds during operation. A CPU Unit service monitoring error will oc-
cur in the Special I/O Unit if it is not refreshed every 11 seconds.
