How it works

Downloading or uploading the system configuration

In a multiuser system, the settings from System Configuration are saved in the configuration database, [MyConfig].mdb. This file is one of the four core configuration files shown in the illustration below.

Typically, the IGSS configuration and the system configuration are maintained on the IGSS server. When changes are made to either, they are automatically downloaded to the operator stations in the system.

It is also possible, however, to make changes to the configuration or the system configuration on one of the operator stations and then upload those changes to the IGSS server. In that case, the changes are first uploaded to the IGSS server which, in turn, makes sure that all the remaining operation stations are updated.

Overview

The illustration below gives you an overview of how the system configuration is distributed in a multiuser system.

Initial setup explained

The following steps outline how you set up a multiuser system the first time. For detailed step-by-step procedures, refer to the "How To" book in the Table of Contents.

The configuration is created on the IGSS server.
All the stations of the system are defined and set up.

From the IGSS Server you can set up the parameters for all the stations in the system. This makes it a lot easier to make the setup of the individual stations consistent.

The communication drivers and PLCs are set up.
The mimic diagrams are configured on the IGSS server and the IGSS configuration is installed.
On each operator station, the following is done:

Open the System Configuration program and specify the station type and name. The name must be exactly the same as the one specified on the IGSS Server.
Launch the IGSS Starter program. When prompted for the server's address, specify the IP address of the IGSS Server.
The IGSS configuration is now downloaded including the file [MyConfig].mdb which includes the entire system configuration.

When you subsequently open the System Configuration program on the operator station, the appropriate station name will be highlighted in the tree view. The parameters for the station have also been downloaded from the IGSS Server.
The IGSS configuration is now identical on all stations of the system. When changes are made on one of the stations in the system, they are automatically distributed to the other stations of the system. If required, the system can be set up to display a message before changes are downloaded or uploaded.
