5.5 Defining Peerlink II Services
The
FMS CP module supports a maximum of 32 Peerlink II services, as
shown in Figure 5-9. The FMS CP module transmits and receives data (in
the form of peer blocks) to and from other SIMA
TIC 505 FMS CP modules
on your network on a scan-by-scan basis. When you click on Peerlink II
Services on the configuration tree, the COM5434 Configurator displays the
number of T
ransmit and Receive blocks available.

o configure Peerlink II Services, define the desired transmission interval
and priority factor
, and then configure the individual peer function blocks.
Peer Transmit Interval Enter
a numeric value, from 0 to 65,535 (scan
cycles), to specify how often the T
ransmit peer block transmission is
attempted.
Peer Priority Factor Enter
a numeric value, from 0 to 8, to specify the
priority for writing received peer data blocks to the PLC versus other
communications activities (e.g., FMS jobs). A factor of 8 specifies the
highest priority for received peer data, but still allows other activities if
no peer receives are pending. A factor of 0 is the lowest priority
, but
still allows peer receives if no other activities are pending.
