3.2.9 Peer Cop Health MSTR Operation
The peer cop health operation
t
pe 9 in the displa
ed re
ister of the top node
reads selected data from the peer cop communications health table and loads that
data to specified 4
x
re
isters in state RAM. The peer cop communications health
table is12 words lon
, and the words are indexed via this MSTR operation as words
0 ... 11.
Control Block
Utilization
The re
isters in the MSTR
control block
the top node
contain the information for a
Peer Cop Health operation as described in the followin
table:
Peer Cop
Communications
Health Status
Information
The peer cop communications health table
shown below
comprises 12
conti
uous re
ister that can be indexed in an MSTR operation as words 0 ... 11.
Each bit in each of the table words is used to represent an aspect of
communications health relative to a specific node on the TCP/IP network:
The bits in words 0 ... 3 represent the health of the
lobal input communication
expected from nodes 1 ... 64. Since
lobal input is not supported these bits are
set to zero.
The bits in words 4 ... 7 represent the health of the output from a specific node.
The bits in words 8 ... 11 represent the health of the input to a specific node.
