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 Failover Cluster Administrator is included in the Microsoft® Windows® Server 2012, Microsoft® Windows® Server 2012 R2, and Microsoft® Windows® Server 2016 operating systems.

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.

  • Must have a dependency on that shared drive where the files are located.

The project is:
  • A resource.
  • Dependant on the physical disk.
  • Assigned to a cluster.
  • Started either 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 on Windows Servers

Important: 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 .
