About the CIMPLICITY Cluster Resource

CIMPLICITY Cluster, which is incorporated into the Microsoft Cluster technology, is available in Proficy™ HMI/SCADA CIMPLICITY® version 6.2 or higher.

A license is required to run CIMPLICITY on a cluster. If you do not have a license you can configure a project, open it from the Workbench and run it as you would any CIMPLICITY project. However, it cannot be started by the Cluster Manager and will not have the cluster benefits. The license is programmed into your hardware key .

CIMPLICITY cluster resource overview

Note: The Microsoft Cluster Administrator is included in the Windows 2003 operating system.

See Microsoft documentation about cluster administration and requirements.

When you include CIMPLICITY in a cluster, the project:

Must:

Be on a drive that is connected to more than one node.

The drive can have a maximum number of eight connected nodes.

Have a dependency on that shared drive where the files are located.

Is:

A resource.

Dependant on the physical disk.

Assigned to a cluster.

Started:

When the cluster is brought online, or

In the Workbench, which can be opened through the resource's Properties dialog box.

The Cluster reports the project status depending on where the project is started, as follows.

Start Project through the:	Then the cluster will:
Cluster	Watch the project. Indicate that it is online.
Workbench	Watch the project. Indicate that the project is off line until you bring it online (through the cluster).
Workbench And Bring it online through the Cluster	Watch the project. Indicate that it is online.

The Cluster reports the project status depending on where the project is started/stopped, as follows.

Start Project through the:	Stop Project through the:	Then the cluster will indicate that the:
Cluster	Workbench	Project failed.
Workbench	Workbench	Project is off line.

The CIMPLICITY Router keeps track of what IP addresses are in use on the computer.

Important: You cannot use the cluster IP address as one of the IP addresses so CIMPLICITY will not listen for incoming connections on the cluster IP address.

CIMPLICITY cluster resource example

CIMPLICITY files are installed on Drive G:

Drive G: is connected to four nodes.

Node 1 currently controls G:.

Nodes 2, 3 and 4 will not be able to access the CIMPLICITY project until it fails over or is moved. The node it fails over or is moved to will then be in control of the project instead of Node 1.

Configuration steps

Step 1	Add a CIMPLICITY resource to the Cluster Administrator.
Step 2	Open a CIMPLICITY Project Resource Dialog Box
Step 3	Configure the CIMPLICITY Resource Parameters
Step 4	Configure other Properties for the CIMPLICITY Project Resource
