3.1 Product Specifications
ProLinx Communication gateways are the ideal solution for bridging
communication between networks that use differing protocols. ProLinx gateways
provide several protocol combinations, allowing for a wide range of flexibility in
establishing a network, or fitting into and expanding your current infrastructure.
Coupled with ProSoft’s radio technology, you can easily integrate devices into
your system wirelessly, and without the need to purchase additional radios to do
so.
3.1.1 General Specifications - ProLinx
ProLinx ® Communication gateways provide connectivity for two or more
dissimilar network types. The gateway, enclosed in sturdy extruded aluminum,
are stand-alone, DIN-rail-mounted solutions that provide data transfer between
many of today’s most widely used industrial automation protocols.
3.1.2 Internal Database
The ProLinx gateway contains an internal database that consists of areas for
application data, status information, and configuration information.
The internal database is shared between all ports on the gateway and is used as
a conduit to pass information from a device on one network to one or more
devices on another network.
Application Data Area
The protocol drivers exchange data by storing and retrieving data from a shared
application memory data area. The database is used as a source for data to be
sent to remote devices and holds data received from the remote devices. For
protocol drivers that act as Masters or Clients, commands defined in the
configuration file (stored in the configuration data area) control how the data is to
be handled in the database. For protocol drivers that act as slaves or servers,
the remote Master or Client must be properly programmed to send data to or
request data from the correct memory addresses in the gateway application data
area.
Status Data Area
This area stores error codes, counters, and other status information.
Configuration File
This file contains gateway configuration information such as port configuration,
network information, and command configuration. This configuration file is
transferred to or from the gateway.
