Web Server

Introduction

The TM3 bus coupler supports a Web server, offering access to information such as configuration data, module status, I/O data, network statistics, and diagnostic information.

In addition the Web server allows you to monitor this information, the bus coupler network and I/O remotely.

You can access the Web server with HTTPS (secured connections). HTTP (non secured connections) is not supported.

The Web server is accessible through the bus coupler USB port and Ethernet port by specifying the IP address or hostname in the address bar. You can use the pages of the Web server for network setup and control the I/O module outputs as well as application diagnostics and monitoring.

Use a PC providing a USB port and/or an Ethernet interface to connect to the Web server by using a Web browser.

The Web server can be accessed by the web browsers listed below:

Google Chrome (version ≥ 71)
Mozilla Firefox (version ≥ 64)
Microsoft Edge (version ≥ 42)

The Web server allows you to monitor a bus coupler remotely, to perform various maintenance activities including modifications to output modules data and network configuration parameters. Care must be taken to ensure that the immediate physical environment of the machine and process is in a state that will not present safety risks to people or property before exercising control remotely.

WARNING
	UNINTENDED EQUIPMENT OPERATION Define a secure password for the Web server, and do not allow unauthorized or otherwise unqualified personnel to use this feature. Ensure that there is a local, competent, and qualified observer present when operating on the controller from a remote location. You must have a complete understanding of the application and the machine/process it is controlling before attempting to adjust data, stopping an application that is operating, or starting the controller remotely. Take the precautions necessary to ensure that you are operating on the intended controller by having clear, identifying documentation within the controller application and its remote connection. Failure to follow these instructions can result in death, serious injury, or equipment damage.
