# Honeywell Uniformance Process History Database (PHD)

A PHD data source represents data from Honeywell PHD servers in JUNE5. All metrics on the PHD server can be assigned to a JUNE5 PHD data source. The connection between JUNE5 and the PHD server is established via a PHD .NET wrapper.

{% hint style="info" %}
A user in PHD is required who has at least read access to the variables and measured values.
{% endhint %}

## Supported PHD Client Functionalities

* Browsing of metrics
* Reading historical raw data
* Reading aggregated data (averages)
* Synchronizing tags

Two types of data can be displayed in JUNE5 via the PHD data source: raw data and aggregated data. Aggregated data consists exclusively of averages. Additionally, the read data is filtered according to its data quality so that the values to be considered have above-average data quality. Since data quality values can range between 0 and 100, only those values whose data quality is equal to or higher than 50 are considered.

In JUNE5, only the identity of PHD server users can be verified. Therefore, anonymous access and access by Windows users to the data of the PHD server are blocked.

Supported are PHD systems in versions R321, R400, and R430.

## Synchronization

When synchronizing the data source, all tags of the PHD server are read and compared with the already configured tags. All tags in the JUNE5 database that are no longer present in the PHD data source are deleted during the synchronization process.

## Licensing

A JUNE5 license (Enterprise) with the option Data Source Honeywell Uniformance Process History Database (Order No. JUNE5-OPTN-DS-PHD) is required.

## Port Number of the PHD Server

{% hint style="info" %}

* For a local PHD server, use 3100 (default setting).
* For a remotely installed PHD server, use 3150 (PHD server is accessible on the network).
* If you attempt to contact a remote PHD server with the default value of 3100, the PHD interface will automatically change the port to 3150.
  {% endhint %}

For remotely installed PHD servers, the firewall must be configured by IT according to the above instructions.

Use the PHD tools ***PHD MAN*** and ***PHD READ*** to check whether archives and data are available for individual variables.
