Description
3.8 SIMATIC PDM
SITRANS P DS III with PROFIBUS PA
36 Operating Instructions, 06/2013, A5E00053276-07
SIMATIC PDM is a software package for configuring, parameter assignment, commissioning,
diagnostics and maintenance of this device and other process devices.
SIMATIC PDM offers simple monitoring of process values, alarms, and device status
information of the transmitter.
SIMATIC PDM allows the process device data to be:
● displayed
● set
● modified
● saved
● diagnosed
● checked for plausibility
● managed
● simulated
The Process Fieldbus (PROFIBUS) is an open communications system for automation
technology and is specified in the international standard IEC 61158.
PROFIBUS Process Automation (PROFIBUS PA) is a variant of PROFIBUS Decentral
Peripherals (PROFIBUS DP), which is widely used in process technology.
PROFIBUS PA uses a special transmission technology, enabling it to fulfill the requirements
of process automation and process technology. This transmission technology is defined in
the international standard IEC 61158-2. The low transmission rate reduces the power loss in
comparison to PROFIBUS DP, enabling an intrinsically safe technology for use in hazardous
zones with explosive atmospheres. The PROFIBUS PA and PROFIBUS DP protocols are
identical.
The bus topology is mainly able to be selected as desired. Therefore, line, star and tree
structures, and mixed forms are possible. All types of field devices such as transmitters,
actors, analysis devices, etc. can be connected to the PROFIBUS PA.
Advantages include:
● Savings on installation costs
● More extensive diagnostics, leading to increased availability of installation sections
