SIMATIC PDM

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.
SIMATIC PDM allows the process device data to be:
● displayed
● set
● modified
● saved
● diagnosed
● checked for plausibility
● managed
● simulated
Additional information on SIMATIC PDM can be found at SIMATIC PDM instructions and
manuals

PROFIBUS PA

3.5.1

Overview

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.
3.5.2

Transmission 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.
