The "Advanced Principles of FOUNDATION Fieldbus" course covers FieldComm Group tools used for FOUNDATION Fieldbus development. Students will work with the bus monitor to understand its basic use and learn how to apply this tool in interactive exercises demonstrating fieldbus communications and the use of filters for network troubleshooting.
The course covers H1 and High Speed Ethernet (HSE) communications between fieldbus devices. For H1 communication, emphasis is made on synchronous and asynchronous communication and the configuration and responsibility of the Link Active Scheduler (LAS). Students will examine the detailed messaging described in the System Management Specification for address assignment, tag assignment, and time distribution. The HSE communication protocol is explored in detail to understand the implementation of linking devices and HSE field devices.
Students will study the details of the object dictionary for H1 and HSE devices. This is especially important to the device developer, as the object dictionary is used to describe all the parameters and objects accessible over the fieldbus network. Students will study the layout of the object dictionary and examine an actual object dictionary in registered devices.
The "Advanced Principles of FOUNDATION Fieldbus" course covers the requirements for building a function block application. This includes mode and status generation and propagation, resource and alert state machines, cascade handshake, and vendor-specific extensions. The course examines Device Description (DD) technology. Students will look at how the connection is made between the DD binary file and the object dictionary.
Lastly, students will learn how to effectively navigate the FOUNDATION Fieldbus specifications in order to find information relevant to particular development tasks.
Throughout the course, live demonstrations of an interoperable fieldbus using registered products will be configured and analyzed using both dialog tools and bus monitors. Students will also reference the FOUNDATION Fieldbus specifications in exercises designed to improve familiarity with the documents and the search capabilities built into the specifications package.
