Redundancy Hot Standby

7.3

Further information on

SYSCON

operation, can be found in its own manual.

For any of the redundancy modes it is necessary first of all to configure the network redundancy.
The next section explains how to do it.

Configuring the Network Redundancy

In order all the OPC-Client tools be able to deal with network redundancy it is necessary configure
the workstation and the DFI OLE Server.

Configuring the Workstation

It is possible to have one or two workstation (redundancy of workstation). Here follows the steps for
the configuration.

1 - Each workstation must have an HMI installed.

2 - Each workstation must have installed two NICs (Network Interface Card).

3 - Each NIC must be configured in a different subnet range (e.g. NIC1, IP=

192.168.164

.50 / Subnet

Mask 255.255.255.0 and NIC2, IP=

192.168.163

.50 / Subnet Mask 255.255.255.0).

4 – Configure also the default gateway according to the specific requirements.

5 - Install two HUBs or switches. Each NIC must be connected to one of them in such a way that

two LAN are assembled isolated from each other.

6 - That way, each one of the MB-700 modules can be connected to one of the HUBs obeying the

subnet ranges predefined (e.g. First MB-700, IP=

192.168.164

.51 / Subnet Mask 255.255.255.0

and Second MB-700, IP=

192.168.163

.51 / Subnet Mask 255.255.255.0).

7 - To test the network configuration, a

ping

command to each one of the MB-700 modules can

confirm if everything is working fine.

Configuring the DFI OLE Server

There are two ways to configure the OLE Server for network redundancy: Here follows the steps for
the configuration in each case.

The HMI Client chooses the DFI OLE Server (local and remote).

In this case, the local Server has a specific NIC adapter and the Client chooses what server will be
used.

Figure 7.2 – Example of Data Supervision with Management of Redundancy by OPC with a

only net board in each Workstation

1 - Configure in the file SmarOleServer.ini, the NIC adapter that will be used on each workstation

ports (e.g. First workstation, NIC=192.168.164.50 and Second workstation,
NIC=192.168.163.50).

2 - Doing so, each DFI OLE Server will choose the specified NIC adapter.
