■
Overview
•
SOFTNET-IE RNA (Redundant Network Access is the software
for connecting a PC to networks with PRP (
P
arallel
R
edun-
dancy
P
rotocol in accordance with IEC62439-3) capability
•
High level of plant availability thanks to duplicate transmission
of frames in two parallel, separate networks
•
Reconfiguration times in a subnetwork do not affect the
propogation time because the frames are transmitted via two
separate networks (bumpless redundancy)
•
Integration in network management systems through support
for SNMP
•
Configuring tools are included in the scope of delivery of the
communication software in each case
■
Benefits
•
Increases the availability of the PC application by establishing
Industrial Ethernet networks with high network availability
(bumpless media redundancy through parallel data transfer in
parallel networks)
•
High availability of the overall plant
•
No additional programming overhead required in the PC
•
Secures the investment thanks to the use of existing applica-
tions and flexible application options
•
Simple integration into existing network management systems
thanks to access to diagnostic data via SNMP as the standard
interface
■
Application
The SOFTNET-IE RNA software package enables low-cost
connection of non-PRP-enabled terminal equipment to parallel,
separate networks in which high availability is demanded.
■
Function
•
Connection of PCs to parallel, separate networks (PRP)
•
Parallel data transfer over two parallel, separate networks
•
Simple diagnostics via SNMP
Configuration
A configuration tool is included in the scope of delivery of the
software package.
