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.
Fig.2-1 Overview of the SINUMERIK 840Di Hardware basis The hardware basis of the SINUMERIK 840Di is a SIEMENS industrial PC in conjunction with a PCI plug-in board, the so-called MCI Board (Motion Control Interface), which has been developed by Siemens. Depending on the variant of the industrial PC used, a different number of OEM or end user PC boards (PCI or ISA) can be plugged optionally.
He will reduce the logistic expenditure for the PC technology as such (procurement, qualification). • He will benefit from the advantage that Siemens is well known and spread all over the world (sales/marketing and service). Consistency to the SINUMERIK 840D A special feature of the SINUMERIK 840Di is the consistency to the SINUMERIK 840D.
Fig.2-2 The SINUMERIK 840Di hardware (system overview) Hardware basic variant The basic variant of the SINUMERIK 840Di is a compact SIEMENS industrial PC and a PCI plug-in board, the so-called MCI Board (Motion Control Interface), which has been developed by Siemens.

For the specification of this profile, please refer to: PROFIDrive Profile, Drive Technology, Draft V1.4.2, 01st Sept., 00 With the SINUMERIK 840Di, it is thus possible to control drives from the NC in speed/torque control mode and from the PLC in Positioning mode. To achieve this, NC and PLC can internally access the PROFIBUS-DP interface of the MCI Board at the same time.

• Asynchronous motors: 1PH., 1LA. with/without encoder • Non-Siemens motors if these are suitable for converter mode. SIMODRIVE 611 universal E SIMODRIVE 611 universal E is a closed-loop control module without positioning functionality and a reduced number of interfaces and encoder connection possibili- ties, which generally corresponds to the SIMODRIVE 611 universal.
From the range of devices of the distributed I/O system SIMATIC ET 200, all I/O devices can be used which support a data transfer rate of 12MBaud to be set with the SINUMERIK 840Di at PROFIBUS DP. These are currently the following I/O de- vices: •...
Windows NT and/or to the PLC. The appropriate functionality for the PLC user program is provided by Windows NT or the PLC/SINUMERIK 840Di; now, the control system can be shut down correctly. To create a suitable UPS system, e.g. the following components can be used: •...
02.2001 Windows NT The operating system basis of the SINUMERIK 840Di is Windows NT 4.0 (US ver- sion). Since, however, it is well known that Windows NT is only conditionally real- time capable (the term 'smooth real time' is used in this context), Siemens has de- veloped a method enabling the NC system software to be operated under hard real time conditions, without modifying Windows NT.
• Integrated high-level language commands (control structures, program coordi- nation, etc.) A complete list of all NC functions provided for the SINUMERIK 840Di by default or optionally is to be found in: Catalog NC 60·2000/2001, Chapter 2, Overview of Functions...

The HMI Configuring Package based on SIMATIC ProTool/Pro has been con- ceived for the visualization and operation of machines and small installa- tions/systems. The additional SINUMERIK option is required to configure a SINUMERIK 840Di and the operator panels of this control system using ProTool/Pro. •...
Power failure Power failure If the SINUMERIK 840Di is switched off by the user or as a result of a power failure so that a correct shutdown of Windows NT is no longer possible, the retentive NC and PLC data can only be stored in the SRAM of the MCI Board, but no longer on the hard disk of the PCU.
Alarm with the axes stopped by the NC • Alarm and drive-independent stopping of the axes The real time behavior of a SINUMERIK 840Di can be watched using the NC/PLC system diagnosis included in the 840Di-Startup user interface. Certification of extensions To be able to offer high quality and reliability performance of the whole system, a SINUMERIK 840Di is supplied completely configured and ready to operate.

SINUMERIK 840Di and must be acquired separately. Basic start-up After a SINUMERIK 840Di has been turned on for the first time, a basic start-up of the control system has to be carried out which includes the installation of the system software on the PCU and the parameterization of NC and PLC with predefined default values such that a first test of the system can be carried out with, naturally, simulated machine axes.
PLC and NC is included in the scope of supply of the SINUMERIK 840Di in the form of a SIMATIC S7 library. In addition, the scope of supply of the SINUMERIK 840Di also includes a sample hardware configuration which can serve as an example or extendable basis to create the final configuration.
