State monitoring parameters
The state monitoring parameters are used to allocate areas in the PMC
area to which the states of the local node and other nodes are posted.
Table 1-10 Area 1 Allocation Parameters
Item Description
OWN STATUS
Pa20
Specify the start address of an area in the PMC E/R
area to which the communication state of the local
node is posted.
An 8-byte area starting at the start address is used
as the local node status area.
ENTRY NODE
Pa21
Specify the start address of an area in the PMC E/R
area to which the network participation state of other
nodes is posted.
A 32-byte area starting at the start address is used
as the participating node list area.
CAUTION
1 The E area in the PMC area is normally allocated
to volatile memory. It, however, can also be used
optionally as nonvolatile memory.
When the area is set as nonvolatile memory, the
contents of the area 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 or E 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 When the above area is not used, enter a space.
"---" appears, indicating that the area is not used.
2 Only a PMC area at an even-numbered address
can be set for the above area.
