DATA COLLECTION MANAGEMENT FEATURE AUTOMATED QUALITY MANAGEMENT SYSTEM G
erman based measuring technology specialist, Heidenhain and statistical
software company, Q-DAS, whose main focus is on quality management applications, have teamed up to provide a solution for data management. The two companies are offering an integrated system for automatically collecting, analysing and archiving data from up to 250 measurement channels. In the UK and Ireland, support is provided
jointly by Heidenhain (GB), Burgess Hill and Q-DAS distributor, Measurement Solutions, Peterborough. The multi-channel multiplexer, MSE 1000, is at the heart of the system. It comprises a choice of power supply module, a communications module and a variety of interface modules for receiving many different types of signal. They include sinusoidal 1 Vpp, EnDat 2.2
signals from incremental and absolute linear and rotary encoders, TTL (transistor- transistor logic), RS-485, inductive signals from LVDTs (linear variable differential transducers) and HBTs (half bridge transducers), and analogue signals. For closed loop in-process gauging, I/O (input/
output) modules can be provided for digital signals as well as a compressed air switching module for directly controlling pneumatically activated length gauges. Displacement sensors from leading manufacturers are supported. All modules are mounted to a DIN rail in
an electrical cabinet to achieve an organised and compact measuring station, data transmission being via standard Ethernet. MSEsetup software is provided to allow the user to configure all of the connected channels. It has diagnostics for

Heidenhaim and Q-DAS have teamed up to offer an integrated system for automatically collecting, analysing and archiving data from up to 250 measurement channels
connected sensors and modules and allows automatic transfer to a PC via Excel for data collection. If an application calls for further integration, the DLL files are made available for custom programming. Evaluating measurements and transforming them into useable results is where the Q-DAS software comes in. The company’s current procella version 11 integrates with MSE 1000, for which driver support has been implemented. The full range of procella software functions have been made available, simplifying handling of the measuring station and enabling all channels to be configured. Collected measurement and test data are saved into files or stored in a central database. The information is then instantly available for quantitative and qualitative evaluation. Direct visualisation of the recorded values combined with the display of historical data enables early recognition of trends. It allows the operator to identify issues quickly as they arise and implement corrective actions to the process, minimising loss of production.
