System Overview
SIMATIC 545/555/575 System Manual
Overview (continued)
Series 505 programmable control systems can now communicate with
PROFIBUS-DP I/O and other devices that meet the PROFIBUS standard
(DIN 19245, Part 3). PROFIBUS-DP is a token ring protocol in a
master-to-slave configuration that is optimized for I/O exchange.
Some Series 505 CPUs contain a PROFIBUS-DP annex card (optional for
575 and 545–1103/–1105 CPUs) that supports all I/O devices that conform to
the PROFIBUS-DP standard. New model 545–1106 and 555–1105/–1106
CPUs have the PROFIBUS-DP I/O port integrated on the board.
The PROFIBUS-DP I/O channel allows you to greatly expand the type and
quantity of your remote I/O, as well as increase communication speed. The
following features are available on the PROFIBUS-DP I/O channel:
•
All CPUs except the 545–1103/–1105 can support up to 112
PROFIBUS-DP addresses for master and slave devices.
•
The 545–1103/–1105 CPUs support up to 32 PROFIBUS-DP addresses
for master and slave devices with the optional PROFIBUS annex card.
•
Token passing to a programming device is supported.
•
Baud rates are user-selectable from 9600 baud to 12 Mbaud.
•
All consistent data requirements of PROFIBUS-DP slaves are
supported. (Using consistent data, however, reduces the number of
slaves you can connect due to increased memory requirements.)
To configure PROFIBUS-DP I/O for Series 505 CPUs, you must use the
COM PROFIBUS configuration utility in conjunction with TISOFT; consult
the SIMATIC 505 TISOFT2 User Manual.
PROFIBUS user organizations exist in a number of countries to allow
PROFIBUS users to exchange information. The address of the organization
in the U.S.A. is as follows:
