Area 2 allocation parameters
The area 2 allocation parameters are used for allocation-related
settings to enable data exchange between common memory area 2 and
the PMC R area.
Table 1-9 Area 2 Allocation Parameters
Item Description
AREA2 DO:
ALLOCATION
Pa40
Start address of an area in the PMC R area or D area used for
DO data exchange with common memory area 2.
This parameter allows only an even address to be set.
AREA2 DO:
SIZE(Note 1)
Pa41
Size of DO data exchanged between common memory area 2
and the PMC R area or D area (Unit: Words).
When DO data exchange between common memory area 2
and the PMC is not performed, set 0 in this parameter.
AREA2 DI:
ALLOCATION
Pa42
Start address of an area in the PMC R area or D area used for
DI data exchange with common memory area 2.
When DI data exchange between common memory area 2
and the PMC is not performed, set -1 in this parameter, or
press soft key [DISABL].
This parameter allows only an even address to be set.
AREA2 DI:
ALLOC PTR
(Note 2)
Pa43
Set an area in the PMC R area used to specify a node from
which data is to be read as DI data.
When DI data exchange between common memory area 2
and the PMC is not performed, set -1 in this parameter, or
press soft key [DISABL].
This parameter allows only an even address to be set.
AREA2 DI:
CHANGE FLG
(Note 2)
Pa44
The user can dynamically switch between nodes from which
data is to be read as DI data.
Specify an area in the PMC R area used to specify switch
timing.
When dynamic switching is not performed for reading DI data,
set -1 in this parameter, or press soft key [DISABL].
AREA2 DI:
AREA2 ADDR
(Note 2)
Pa45
Start address of common memory area 2 to be statically
allocated in the PMC area as DI data
AREA2 DI:
AREA2 SIZE
(Note 1, Note2)
Pa46
Size of DI data statically exchanged between common
memory area 2 and the PMC area (Unit: Words)
NOTE
1 The unit of size set in this parameter is words. This
means that for an area used in the PMC R area, the
number of bytes as many as the size set in this
parameter multiplied by 2 is required.
2 Parameters AREA2 ADDR and AREA2 SIZE can be
used to set a large area for data exchange between
common memory area 2 and PMC area
independently of node numbers.
When a value of 0 is set for AREA2 SIZE, no static
allocation is performed and dynamic DI data change
