1.SETTING OF FL-net FUNCTION SETTING B-64164EN/01
- 86 -
CAUTION
1 When nonvolatile memory in the PMC area is used,
the memory contents are retained even after the
power is turned off. So, special attention should
be paid not to cause an unpredictable operation
when the power is turned on next time.
2 When setting the PMC area, note the following:
The R address, E address, or D address can be
set.
For a multi-path PMC, enter an PMC address as
follows:
<Path number>:<PMC address>
For R0500 for the second PMC path, for example,
enter "2:R500". When only a PMC address
(R500) is entered, it is assumed to be the PMC
address for the first path (1:R0500).
If the ":" key is not provided, the "/" or "EOB" key
can be used instead.
3 Be careful not to cause an overlap between an
area such as the input data area of the user
program and a PMC area used for other purposes.
NOTE
1 In these parameters, set a size in words.
Therefore, the area sizes used in the PMC area
require twice as many bytes as the values set in
these parameters.
2 By using parameters Pa45 (area 2 start address)
and Pa46 (allocation size), a large area can be set
between common memory 2 and the PMC area
regardless of the node number.
When Pa46 (allocation size) is set to 0, dynamic DI
data switching is performed for each node without
static allocation.
When Pa46 (allocation size) is set to a value other
than 0, data in common memory area 2 starting at
the start address set by Pa45 (area 2 start
address) is transferred to the PMC area specified
by (Pa42 (PMC start address) plus 4), and dynamic
DI data switching is disabled. In this case, Pa43
(allocation condition setting) and Pa44 (condition
switch flag) are used only for switching node status
information.
