Solutions Handbook (AADvance Controller)

Typical Network Applications

A typical distributed AADvance system uses two networks:

 An information network, which provides connectivity to the BPCS (basic process

control system) and to OPC devices

 A dedicated safety network, which handles data shared between the AADvance

controllers

The engineering workstation may connect to the safety network (as illustrated), to the

information network or to both networks.

As drawn, the OPC portal server collects data from the controllers and displays it on

the HMIs and, conversely, delivers commands from the HMIs to the controllers. The

information network carries real time data (Modbus TCP) from the BPCS to the

controllers.

Specifying a Safety Network

Once a system uses distributed controllers with shared data, the topology of the safety

network must provide some robustness. To do this, make sure the network has no

single point of failure, and refer to the AAdvance Safety Manual (Document: 553630).
