DESCRIPTION
Trusted
provides for the interchange of safety and
non-safety related information between up to
ten Trusted
The Trusted
modules provide Peer to Peer
Communications facilities. The modules will
also support external communications using
Modbus over serial and Ethernet links.
Using the modules to support both Peer to
Peer and external communications will,
however, degrade the performance of Peer
to peer Communications.
The Peer to Peer network employs Ethernet
as its physical layer and UDP/IP as its
transport. The communications interaction
is on a master/slave basis to provide
deterministic behaviour. Separate
Communications Interface modules may be
nominated as master on each Peer to Peer
network. These modules may also be
resident in separate systems.
The Peer to Peer Communications network
media may comprise any Ethernet standard
type. The media interfaces provided by the
Trusted
module are 10BaseT and 100BaseT. The
network may be used to carry other
communications, e.g. data reporting.
However, this will result in less deterministic
behaviour and is not recommended where
Peer to Peer Communications is to be used
for the transfer of safety related information.
Each Trusted
module provides two Peer to Peer
Communications ports. The ports may be
used to support redundant network media or
independent networks. In redundant
network configurations, the most recently
received data will be used. An alternate
network configuration may be constructed
using independent modules. As with all
Trusted
hot-slot repair is supported.

The information to be transferred

defined within the applications programs
as input and output boards in the
standard form. Each output board
specifies a single destination. Multiple
boards are required where the data is to
be transferred to multiple systems.
Board parameters define the identity of
the destination system for outgoing
information, and source system identity
for incoming. Boolean and integer
values may be transferred between
systems.
