Overview

The RTU Configuration feature provides a way to read, and write the configuration data used by an RTU or flow computer. ACM can configure an RTU if the RTU stores its configuration in items/registers and can accept configuration changes through writes to those items/registers. It is simply a means of backup for the device configuration.
This feature is designed to work with any device which reads its configuration from items/registers. As such, the layout of data in those items/registers must be defined by the user. This is accomplished by manually creating an XML file for that layout. After that file is initially created, it will be used as a template when ACM reads the configuration from the device. The initial XML configuration file may be created using any text editor. An editor with XML syntax highlighting is recommended.

Storage Location

These configuration files are stored in the Windows ProgramData folder. The following is the default location:

C:\ProgramData\AutoSol\Communication Manager\7\DataFiles

Any manually created files should be placed in this directory.

File Naming Convention

Three versions of a configuration file can be kept for a given device: Development, Production, and Last Read.

The files are named in the following format:

<ObjectID>_RtuConfig_<Version>.xml

Where ObjectID is the object ID and the suffix can be _Prod, _Dev, or _Read for Production, Development, or Last Read respectively

For example:
1234_RtuConfig_Prod.xml – The configuration file for the device with object ID 1234 when running in a production environment.
5555_RtuConfig_Dev.xml – The configuration file for the device with object ID 5555 when running in a development environment.
9876_RtuConfig_Read.xml – The configuration file for the device with object ID 9876 created by the last run of the Read RTU Configuration command.

Assigning XML Config Files To A Device

Before first use, the initial Last Read file must be created manually as described by device sample files provided in the device RTU Configuration page. This informs the driver of which items/registers to read and store. After the file is created, the file can be controlled & assigned to devices through the ACM Configuration Client by opening the device, selecting the RTU Configuration tab, and selecting the desired type from the drop down list. From there, changes can then be made from the RTU Configuration tab rather than editing the file manually.

The Development and Production files can also be created so the driver can write configuration data to the RTU. Either or both of these files can be created. The Development file is designed as a way to test the configuration data. Once satisfied that the configuration is correct, the Development file can be ‘promoted’ to a Production file. During this process the driver copies the Development file to the Production file. The Production file can be written to the RTU via the ACM command API.
