The PHD Adaptor provides standardised access to Honeywell's Uniformance PHD Desktop Historian servers, hiding the complexity of obtaining data from PHD.<\/p>\n
The PHD Adaptor requires the Honeywell PHD API to be installed to access real-time and historical data from Honeywell's PHD historian. This requires a license for the Honeywell PHD API, which is a third party component.<\/p>\n
A separate PHD 410 64-bit Adaptor is available in the Explorer installer. This has the same capabilities and configuration options as the PHD300 Adaptor, but is designed specifically for 64-bit systems.<\/p>\n
PHD 300 has removed the need to log on using a user name and password, this is now done through the user that is logged on and running the PHD API. In order for IFS OI Server to use this feature, the Adaptor Pool Service must be set to a user that has access to the PHD system.<\/p>\n
The PHD API that is used by the adaptor does not support batch fetching of tags and therefore cannot perform batch fetching. It is recommended that the fetch is done in a single fetch or it is filtered by A-Z; this will depend on how many tags exist in PHD.<\/p>\n
The PHD Adaptor can understand minimum and maximum values that are defined using exponential notation (e.g. -1.643e6 to mean -1643000.0). If the adaptor does not recognise the value configured for a tag\u2019s minimum or maximum, it sets both to \u2018null\u2019 (meaning \u201cunknown\u201d) rather than failing to fetch the tag. In versions prior to Server 4.5.3, these values would be rejected.\u00a0<\/p>\n

While the Default type is normally sufficient, using Remote API may be necessary when connecting to a PHD server residing on a different domain to the machine where the adaptor is running. Options: Default, Remote API.

Options: True, False.<\/td>\n Use Domain Authentication<\/td>\n Boolean<\/td>\n<\/tr>\n \n PHD Single Point Collapse Method<\/span><\/strong><\/td>\n Specifies the handling method when more than one datum is returned for a single-point fetch.

Options: True, False.<\/td>\n Enable Timing Logs<\/td>\n Boolean<\/td>\n<\/tr>\n \n Allow Write<\/span><\/strong><\/td>\n Whether this data source should allow IFS OI Server client applications to write data to tags on the historian.

Changing this setting can, depending on the functions used, significantly affect the results of calculations based on tags from this datasource, should those tags contain such \"null\" points within the fetch range (default: As Historian).
