is performed for each node.
On the other hand, when a value other than 0 is set
for AREA2 SIZE, data starting at AREA2 ADDR in
common memory area 2 is expanded to an area in
the PMC area that is specified by ALLOCATION+4,
and dynamic DI data change cannot be performed.
In this case, ALLOC PTR and CHANGE FLG are
used only for node status information switching.
3 For reasons related to the specifications of the
FANUC FL-net board, set the sizes of common
memory area 1 and area 2 of the local node that are
allocated in the PMC area and the sizes of common
memory area 1 and area 2 of another node that are
allocated in the PMC area so that the total size of
them is 1024 words or less.
For example, when 1024 words of common memory
area 1 and area 2 of the local node are allocated in
the PMC area, DI data of another node cannot be
allocated in the PMC area to read it. Conversely,
when 1024-word DI data of another node is
allocated in the PMC area to read it, DO data of the
local node cannot be allocated in the PMC area. In
such a case, take a means such as dynamic change
of the allocated area so that the total size becomes
1024 words or less. For details, see Chapter II
DESCRIPTION Section 2.6, "Notes on Allocation in
the PMC Area."
4 Data in the PMC D area is also retained after the
power is turned off, then on again. For this reason,
be careful to use the PMC D area. Clear the PMC
D area to 0 using the user program immediately after
power-on as required.
