PROFIBUS-PA

■Overview

PROFIBUS-PA is a fieldbus specially designed for process en- gineering for networking field devices (sensors and actuators) over large distances, even in hazardous areas. Its communica- tion is compatible we PROFIBUS-DP, and it is connected to the automation system via the latter. With the TELEPERM AS 488/TM automation system, connection of two PROFIBUS-DP lines with up to 122 stations each is possible.

The transmission technology of the PROFIBUS-PA corresponds to the international standard IEC 1158-2. A two-wire cable as the transmission medium permits connection of a power supply to the field devices in addition to data communication.

Connecting PROFIBUS-PA to AS 488/TM

Properties and application features of the PROFIBUS-PA

•Networking of transmitters, valves, actuators etc. via a serial bus system

•Communication-compatible extension of PROFIBUS-DP by transmission technology optimized for field devices

•Integration possible into existing fieldbus applications based on PROFIBUS-DP

•Power supply to field devices via data cable

•"Intrinsic safety" (type of protection EEx[i]) permits applications in hazardous area

•Transfer of automation functions (intelligence) into the field de- vices

•Remote parameterization, e.g. using Process Device Manager (PDM)

•Preventive maintenance and diagnostics

•Reduction in hardware and engineering costs by saving of I/O modules, cabling and connections

•Satisfies the requirements of the chemical and processing in- dustries.

PROFIBUS-PA can be connected to the PROFIBUS-DP lines of the AS 488/TM either via the DP/PA link interface module IM 157 or via DP/PA couplers.

Delivery forms

Connection of the PROFIBUS-PA to AS 488/TM is protected by a license program which is linked to the serial number of the AS 488 memory card. Licensing is available in two stages:

•Full license for connection of the PROFIBUS-PA via DP/PA link with transmission rate up to 12 Mbit/s and via DP/PA coupler with transmission rate of 45.45 kbit/s.

•Partial license for connection of the PROFIBUS-PA only via DP/PA coupler with transmission rate of 45.45 kbit/s.
