Objective

The objective of this SOP is to give the reader enough tools to quickly access the web port's web pages and basic instructions on how to configure a Web Port when installing a new one.

Scope

This procedure does not provide all the information needed to set up a web port, nor does it provide instructions on how to build the web port web pages. The user of this SOP should be familiar with PLC's and their inner workings and have some networking knowledge. The configuration section of this procedure is intended to provide the reader an overview of key areas that will need to be configured when installing a web port and the parameters shown will not always be the same as they are site and equipment dependant.

Responsibilities

PSMFC Kennewick staff will be responsible for the configuration of the web ports.

Procedure

Accessing the Web Port's Web Pages

To view the web port's web pages you will need adobe svg viewer installed on your computer. You can obtain the download from the following link. adobe svg viewer.

To access the web port's web pages you will need to know the IP address of the web port. If you have a user name and password you can obtain that information from the following web page:
IP Addresses for Sites

  1. Establish a VPN connection.
  2. Enter the IP address of the web port followed by /usr/viewon/index.html.
    • The URL should look like this http: //webport IP address/usr/viewon/index.html.
  3. This should take you to the main web page. From there you should find links to the other web pages.

The following are examples of the web pages for BCC.
