Introduction - Siemens SINUMERIK 840Di System Overview

Introduction

Control systems based on industrial PC are used in many fields of automation
technology. Moreover, the trend towards control systems completely based on PC
is to be found in many areas, such as woodworking, packaging, handling, bending,
spark erosion, as well as in the field of machine tools and other production
machines. The application and acceptance of control systems in the individual
automation sectors and regions is developed to a different degree, but it is
expected to increase further in future.
Integration
Siemens has taken the first step towards PC based control systems in the area of
the operation with the CNCs SINUMERIK 840C and SINUMERIK 810D/840D. The
new control system SINUMERIK 840Di now represents the consistent continuation
of the SINUMERIK 810D/840D. In addition to the operating functionality, the CNC
functionality is also integrated in the PC.
Decentralization
Another trend in the world of automation is decentralization. More and more
components are relocated from the control cubicle to the system/installation, thus
being as much as possible near the machine. As a result, this provides, on the one
hand, reduced wiring expenditure and, on the other hand, increased flexibility and
reliability. This pertains not only to the I/O modules for input/output signals, but to
an increasing degree also to the drive units.
With the SINUMERIK 840Di, SIEMENS now offers a completely PC integrated
control system that uniformly controls the drive units and I/Os via the standard
PROFIBUS DP with Motion Control functionality, facilitating a distributed design of
the whole system.
The most important features of the SINUMERIK 840Di and the provided
automation components are described in the following Sections.
