Simulation server

System Platform includes a simulated data access server that lets you develop and test a Galaxy before deploying it to your production environment.

The simulation server's hierarchy can be viewed in the Operations Integration Server Manager, within the Operations Control Management Console (OCMC). To run the OCMC, from the Start menu, point to AVEVA and select Operations Control Management Console.

The simulation server is automatically installed on the Galaxy Repository node for Galaxies derived from the Default.cab file, and is always available. It mimics the data output from a PLC. The simulation server sends data to attributes of instances configured for I/O Automatic Assignment in your Galaxy, the same way that a PLC would.

The simulation server contains all the system objects needed to create a functional test environment for testing I/O references that use I/O Automatic Assignment. However, some manual configuration is required before the simulation server can be used. The simulation server includes an Operations Integration server and a PLC simulator.

The simulation server is based on an OPC client device integration (DI) object. You can add it to Galaxies that do not contain it by default. If you need to add the simulation server, you will configure it the same way as you would an OPC client in a normal production environment. Required configuration steps include choosing the server node and server name, and adding scan groups. This process is described in more detail below.

In its default configuration, the simulation server consists of the following elements:

• A channel for OPC communications between your Galaxy and the simulation server. The communications channel has the default name "Port."

• A PLC simulator to generate simulated data for your Galaxy. The PLC simulator has the default name "PLC."

• A device integration (DI) object that is used to link the PLC simulator to the instances in your Galaxy (OI.Sim.1).
