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.
Optional Web Server for Ethernet Solutions
An HTML server is available for Ethernet ProLinx gateways. With this option,
HTML text pages can be enabled to:
Display gateway internal register and status values
Accept user data input values via POST commands for setpoint, on/off
control, and so on.
Provide limited graphic file support
Type Specifications
HTML Server (See note
below) Key features of the HTML server include:
Max HTML page size: 1MB
Max File Storage: 32MB
Supported context types: jpeg, bmp, css
Supported data types: bit, ASCII, integer, float
Sockets: Up to five connections. Note that this limits the number of
simultaneous graphic file and frame references per HTML page
FTP Server Permits remote HTML file transfer between the gateway and remote
host. Capabilities of the FTP Server include:
Single socket connection
Non-passive transfers only
WS_FTP or Command Line FTP recommended
CuteFTP, Internet Explorer, Netscape, or NCFTP all support multiple
socket connections and therefore are not supported by the ProLinx
gateway
Important Note: The Web Server is not designed to act like, or replace, the powerful web servers
available in the marketplace today. Please check application specifics with Technical Support if you
are unsure if your application will work with the ProLinx Web Server.
