S
S7 Configuration S7 Configuration is a tool for parameterizing modules. S7
Configuration is used to set a variety of
--> parameter blocks of the --> CPU and the I/O modules on the
--> programming device. These parameters are uploaded to the
CPU.
S7--300 bus The S7--300 bus is a serial data bus which supplies modules with
the appropriate voltage and via which they exchange data with one
another. The connection between the modules is made by means of
--> bus connectors.
Safety functions The control includes continuously active monitoring functions which
detect faults in the --> CNC, the programmable controller (--> PLC)
and the machine so early that damage to the workpiece, tool or
machine rarely occurs. In the event of a fault, the machining
operation is interrupted and the drives stopped. The cause of the
malfunction is logged and an alarm issued. At the same time, the
PLC is notified that a CNC alarm is pending.
Safety Integrated Effective personnel and machine protection integrated in the control
in conformance with EC Directive >>89/392/EEC<< in >>Safety
Category 3<< to EN--954--1 (Categories B. 1--4 are defined in this
standard) for safe setup and testing.
Discrete fail--safety is assured. If an individual fault occurs, the
safety function is still effective.
Scaling Component of a --> frame which causes axis--specific scale
alterations.
Services Control operating area
Setting data Data which provide the control with information about properties of
the machine t ool in a way defined by t he syst em software.
Unlike --> machine data, setting data can be modified by the user.
