What is DTM?
DTM (Device Type Manager) is a standard way to provide all necessary data and
functionality for a communication device, for example a PROFIBUS DP card.
This technology is similar to the way Microsoft Windows supports printer drivers
supplied by manufacturers and available to any Windows application, rather than
requiring a custom printer driver for each specific application.
PROFIBUS comDTM, distributed by ProSoft Technology, is a DTM for PTQ and
MVI series PDPMV1 modules and ProLinx PDPMV1 gateways. It allows
configuration tools, instruments and communication devices on a field network to
recognize and use the module’s capabilities.
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.
