This platform turns up in many places, and can do many things, but there aren't many that really understand it. Here is a quick guide to explain the basics.
Here is a brief description of each component of the FactoryTalk services platform to give more of an understanding of the capabilities of each:
• Live Data – Provides a live data link between product clients and servers. For example, the connection between the HMI server and a PLC, or between FactoryTalk Historian SE and a PLC. FactoryTalk live data server is for Rockwell Automation devices and will also manage the link between clients and OPC-DA servers for non-Rockwell automation devices.
• Directory – Allows products to share a common address book that finds and provides access to plant-floor resources, such as users, roles, tags and graphic displays. The directory is managed with the FactoryTalk Administrative Console application.
• Audit – Collects messages that document changes done by users during design, management, and operation of production. This is an essential component for FactoryTalk AssetCentre to perform its function as a process control system asset and configuration management tool.
• Security – Provides a range of security services that are integrated into the FactoryTalk directory. The users and user groups are very similar in their management to active directory and can be linked to the active directory. This allows for a centralized authentication and access control which results in a “single user sign-in” experience when using FactoryTalk enabled products.
• Activation – Provides a secure, software-based system for activating Rockwell Software products and managing software activations.
• Alarm & Events – Provides both server-based and device-based process control alarm server.
Hopefully this helps put a handle on the FactoryTalk Services Platform. Keep in mind it is designed to provide a unified factory floor user experience for communication and management of data, users’ accounts, and assets. Also remember that it is a comprehensive services platform, so when considering applications, you need to think in terms of which particular product you’re thinking about, and specify that when discussing individual use cases.
