practical troubleshooting of data acquisition & scada systems
DESCRIPTION
This workshop covers all aspects of data acquisition and control using a PC and data loggers, including design, specification, programming, installation and configuration. The popular IEEE 488 interface is also covered in detail. This hands-on workshop gives both the novice and experienced user a solid grasp of the principles and practical implementation of interfacing the PC and standalone instruments to real world signals. Upon completion of the workshop you will have a thorough understanding of PC based data acquisition systems and will be able to design, specify, install, configure and program data acquisition systems quickly and effectively. An additional aim of the workshop is to cover the industrial communications standards that are used with instruments today. WHO SHOULD ATTEND? Design engineers Electrical engineers Electronic engineers Instrumentation and control system engineers Process control engineers Project engineers Systems engineers Technicians MORE INFORMATION: http://www.idc-online.com/content/practical-troubleshooting-data-acquisition-scada-systems-2TRANSCRIPT
