Runtime software

Reliance's runtime software is a program designed to run a visualization project on the end user's computer. It is used to control and monitor the visualized industrial process. The server modules provide data to connected clients, i.e., either to client instances of the runtime software or to the thin clients (Reliance 4 Web Client, Reliance 4 Smart Client).



Reliance 4 Control

In addition to the features common to all runtime software types, Reliance 4 Control allows displaying visualization windows with real-time data, displaying and acknowledging current alarms, displaying and printing historical alarms, displaying and printing historical data as historical trends and reports, and more. The program and project language can be switched at runtime.


Reliance 4 Control lets you control the visualized industrial process. It is intended for computers with "full control" access (e.g. control workplaces and centers). However, "full control" access can be limited on a per-user basis.

Reliance 4 View

In addition to the features common to all runtime software types, Reliance 4 View allows displaying visualization windows with real-time data, displaying and acknowledging current alarms, displaying and printing historical alarms, displaying and printing historical data as historical trends and reports, and more. The program and project language can be switched at runtime.


Reliance 4 View does not enable you to control the visualized industrial process. It is intended for computers with "view-only" access, e.g. at workplaces of managers who need to view historical trends of process variables and the current status of the process but have no need to control it.

Reliance 4 Server

In addition to the features common to all runtime software types, Reliance 4 Server is a data server for other instances of the runtime software and thin clients. It has a built-in Web server. It provides the clients with data and alarms, executes commands received from the clients and generates reports based on the clients' requests. It runs as a Windows Service and cannot display visualization windows. Therefore, Reliance 4 Server is used as a non-visual data concentrator and a data server. It is especially suitable for unmanned computers.

Reliance 4 Control Server

In addition to the features common to all runtime software types, Reliance 4 Control Server includes all the features of Reliance 4 Control and Reliance 4 Server. It is intended for computers with enough performance to simultaneously handle the operator's requests and requests from client instances of the runtime software and thin clients. For large applications, it is highly recommended that you use Reliance 4 Server running on a separate server to handle the clients' requests.
