About Remote Access

Remote Access is a service for accessing equipment on the customer's network. It consists of a standalone application that the end user needs to download and run — it is not a pure browser-based solution. Web pages can interact with the Remote Access app, for example to launch it with the user's credentials or a selected plant ID.

The service runs on the plant and can, on request, connect to iwmac.net to receive instructions. The service can expose a set of fixed (pre-defined) IP:port pairs or a set of dynamic (scanned) IP:port pairs. It acts as a proxy and routes traffic from the end user to the selected equipment.

The Remote Access app also connects to iwmac.net. It establishes a set of TCP servers hosted on localhost addresses, also acting as a proxy routing traffic to the service on the plant.

How to open Remote Access

If the user has the correct access, the solution can be opened in the following ways:

• Button in Operation Center
• https://iwmac.net/remote_access/
• RAC button in Service Mode

• Carel Boss (http, https)
• AK2 (binary protocol, use AK2 Service Tool)
