To open an implicit
connection, both Producer
and Consumer connection
information is required.
Producer is an active Map
Descriptor, so consumer
should be linked to producer.
The config Map Descriptor
(Rockwell calls it Configuration)
is optional for FieldServer (as
per EIP specs), but it is used by
Controllogix and technically it is
an instance of Assembly Class.
The
address
numbers
are random, but
should be according
to Server information;
at what numbers
server will consume
and produce data.
If not used or set to “-“:
The FieldServer
and remote server both act as producer/
consumer endpoints.
If set to 'Heartbeat' on
wrbc MD: The FieldServer acts as a
consumer only endpoint that produces the
heartbeat; the remote server acts as a
producer only end point.
If set to
'HeartBeat' on passive MD: The
FieldServer acts as a producer only endpoint
and remote server acts as a consumer only
endpoint that generates a heartbeat.
