Operating a system with split domains
Even if there are 64 or less Vnet/IP stations in a system, you can split the domain according to
the operation scope and maintenance unit to enable optimal management of messages in each
domain.
The following figure shows an example of a connection between domains that are split according
to the operation scope for a system integrated with CENTUM and ProSafe-RS. In this example,
CENTUM operation scope A has more than 64 Vnet/IP stations and is split into domains 2 and
3. Operation scope B and ProSafe-RS are located in independent domains, while domain 1
monitors and controls the entire system. By connecting domains as shown in the following figure,
domain 1 can centrally monitor the entire system, while the individual operation scopes can
operate without handling system alarms and operation logs from other operation scopes.

Figure Example of a connection between Vnet/IP domains
You can set the following inter-domain connection methods from the CENTUM engineering
function properties:
• Bi-directional connection: Both domains can receive messages from each other
• Hierarchical connection: Only the upper domain can receive messages
• Bridge connection: Both domains cannot receive messages
If you are downloading recipes from HIS to FCS through domains or performing inter-domain
communications in a ProSafe-RS system, set the “FCS TCP” to “ON” in the domain properties of
the CENTUM engineering function.
