Known Issues and Limitations

Limitations

The following features available in Proficy Historian (on-premises) are not available in Proficy Historian for Cloud:
  • Messages and alerts.
  • Configuration Hub.
  • Enumerated data sets, user-defined data types (UDTs), and array tags.
  • Collector redundancy.
  • Alarms and events archiver.
  • Diagnostics Manager.
  • Historian as an OPC HDA Server and OPC UA DA Server.
  • The File collector, the HAB collector, the Cygnet collector, the Windows Performance Collector, and the Alarm and Events collectors.
  • .NET and CA API. These do not work with Cloud Historian as Cloud Historian is Linux based.
  • LDAP or SAML connections for security configuration for Cloud Historian are not supported.

In general, any features/components for which information is not available in the Proficy Historian for Cloud documentation are not supported.

In addition:
  • The performance of Historian Administrator when connected to Proficy Historian for Cloud is not good. We recommend using the Web Admin console, Excel Add-in for Historian, or the Historian REST APIs instead of Historian Administrator.
  • You cannot back up and restore data using any of the clients. This is because the backup and restore functions are performed using Azure File Shares (AFS). For more information how to set this up, see: https://learn.microsoft.com/en-us/azure/backup/backup-azure-files?tabs=backup-center.
  • Although you can install collectors on-premises or on an Azure Virtual Machine in a VNet, you cannot install the on-premises and cloud versions of collectors on the same machine. You can choose a different machine or uninstall the existing version of collectors.
  • Proficy Historian for Azure Cloud can be deployed in the regions: South Africa North,East Asia, Southeast Asia, Australia East, Australia Southeast, Canada Central,Canada East, North Europe, West Europe, France Central, Central India, South India, Japan East, Japan West, Korea Central, Norway East,Sweden Central, Switzerland North, UAE North, UK South, UK West, East US, East US2, North Central US, South Central US, West US, West US2, and West US3.
