[Explanation of items]
(1) Items
Module side Buffer
size
: Displays the buffer memory size of the setting item.
Module side
Transfer word count
: Displays the number of words to be transferred.
Transfer direction : "
" indicates that data are written from the programmable
controller CPU to the buffer memory.
"
" indicates that data are loaded from the buffer memory
to the programmable controller CPU.
PLC side Device : Enter a CPU module side device that is to be automatically
refreshed.
Applicable devices are X, Y, M, L, B, T, C, ST, D, W, R,
and ZR.
When using bit devices X, Y, M, L or B, set a number that
can be divided by 16 points (examples: X10, Y120, M16,
etc.)
Also, buffer memory data are stored in a 16-point area,
starting from the specified device number. For example, if
X10 is entered, data are stored in X10 to X1F.
(2) Command buttons
Make text file
Creates a file containing the screen data in text file format.
End setup
Saves the set data and ends the operation.
Cancel
Cancels the setting and ends the operation.
POINT
• At the time of auto refresh, the buffer memory contents are batch-read (25 words)
for each channel. The order of storing the data into the CPU module side devices
is the same as that of buffer memory assignment (refer to Section 3.4.1).
• The auto refresh settings are stored in an intelligent function module parameter
file.
The auto refresh settings become effective by turning the power OFF and then
ON or resetting the CPU module after writing the intelligent function module
parameters to the CPU module.
• Auto refresh settings cannot be changed from the sequence program. However,
it is possible to add a process similar to auto refresh by the sequence program.
