Driver Configuration

Plugin Configuration

The plugin configuration file is named settings.json located in <install directory>\Config\HumanOS.UHAL.FileReader\. It contains all global settings of the plugin.

See Generic Plugin Configuration for more details.

Device Information File

The device information file is used to configure the access to files. It contains:

• Id: unique device id (GUID)
• DriverId: 94CAFEC2-7910-41F6-8185-C35CA768FABA
• Address: Connection address
• Data Access

See Device Information Model for more details.

Connection Address

The plugin is designed so that one device info file must be created for each monitoring XML or JSON file. The address points to the monitored file (path).

NOTE

Environment variables inside the path are resolved, e.g. %userprofile%.

Examples:

Type	Example	Resolved path
Absolute	C:\Temp\FileToRead.json	C:\Temp\FileToRead.json
Relative	.\Files\FileToRead.json	${AppConfig:CommonAppPath}\Files\FileToRead.json
Environment variable	%userprofile%\Files\FileToRead.json	for windows typically C:\Users\${username}\Files\FileToRead.json

Additional Properties

The property Encoding allows to specify the file encoding. If the property is not specified, the standard encoding of the operating system is used.

Following values are possible for the property "Encoding":

Property Value	Description
ASCII	US-ASCII encoding
Unicode	Unicode (UTF-16)
BigEndianUnicode	Unicode (Big endian)
UTF7	UTF-7 encoding
UTF8	UTF-8 encoding
