5.3.2 Introduction to PROFIBUS comDTM
Why Use PROFIBUS comDTM?
Customers from around the world have different machines, fieldbusses, and
other end-user equipment. Each is equipped with the field bus requested by their
end-user. Since there are so many variations, the automation solution in their
standard machine ends up being different from case to case.
This means that service engineers need to have different configuration tools for
every fieldbus. Or maybe even one for every device. You want one, but the
reality is you have many. This is where PROFIBUS comDTM can help with
configuring and communicating with different networks, products and suppliers.
What is PROFIBUS?
PROFIBUS (Process Field Bus) is a widely-used, open-standards protocol
created by a consortium of European factory automation suppliers in 1989.
PROFIBUS is a Master/slave protocol. The Master establishes a connection to
the remote slave. When the connection is established, the Master sends the
PROFIBUS commands to the slave.
PROFIBUS supports a variety of network types. The network type supported by
the PTQ and MVI series PROFIBUS modules is PROFIBUS DP (Device Bus)
version 1.0, which is designed for remote I/O systems, motor control centers, and
variable speed drives.
What is FDT?
FDT (Field Device Tool) is the specification for software interfaces for the
integration of field devices, drives, and controls in engineering and configuration
tools. FDT is manufacturer-independent and allows for trouble-free
parameterization and configuration of the user's specific processing system.
FDT technology standardizes the communication interface between field devices
and systems. The key feature is its independence from the communication
protocol and the software environment of either the device or the host system.
FDT allows any device to be accessed from any host through any protocol.
The FDT container implements the FDT specification. It serves as an interface
between FDT and a superior application. It uses the DTMs to gain access to the
devices. FDT frame application is an engineering or configuration tool which has
an FDT container.
FDT technology comprises three key components: the Frame Application, Device
DTMs, and Communication DTMs.

The DTM (Device Type Manager) is used for the configuration and
maintenance of field devices, drives and so on. It is only functional with an
FDT container.

The FDT container implements the FDT specification. It serves as interface
between FDT and a superior application. It uses the DTMs to gain access to
devices.

FDT frame application is an engineering or configuration tool that has an FDT
container. The user interface of the DTMs is displayed here.
