PROFIBUS-DP
PROFIBUS-DP (DP being a German abbreviation for distributed I/O) is used
for switching devices with higher communication requirements (e.g. the
transmission of analog actual values with extremely fast response times). It
is also used to link individual AS-Interface segments.
1.6.2 Parameterization of PROFIBUS-DP and bus-capable low-voltage switching devices
Before commissioning, PROFIBUS-DP must be configured, and the individ-
ual bus nodes must be parameterized. There are user-friendly tools available
to the user for configuration and parameter assignment.
Parameter assignment
tools
• For SIMATIC S7 masters, all the functions are integrated in the STEP 7
programming language.
• For SIMATIC S5 masters and various non-Siemens masters, the COM
PROFIBUS parameter assignment software is required.
• Manufacturers of non-Siemens masters offer other configuration and
parameter assignment programs.
Applications
The above program packages make it easy to carry out the following for
PROFIBUS-DP and its nodes:
• Configuration
• Parameter assignment
• Documentation
• Commissioning
• Testing
• Diagnostics
For additional information on communication-capable low-voltage switching
devices, as well as system components and accessories, see the following
catalogs:
• ST 70 "S7, M7 and C7 Programmable Logic Controllers"
• IK PI "Industrial Communication and Field Devices"
1.6.3 Actuator-sensor interface (AS-Interface)
The actuator-sensor interface (AS-Interface) is a modular networking system
for sensors and actuators in the lowest field range.
It makes no difference to the program in the programmable controller
whether parallel wiring with input/output modules or AS-Interface is used. It
is therefore possible for existing systems to change to AS-Interface because
you can continue to use the same programs. The entire system can be oper-
ated without additional software. It is not necessary to be familiar with the
internal workings of AS-Interface.
