Power Quality Monitoring

▼Chapter 6Touch panelsGeneralJPC150 application exampleIn order to monitor electrical data at site, so-calledembedded systems provide solutions in the formof touch panels. Due to the fact that only slighttolerances are permitted for production machinesand processes and that stand stills outside of certainmaintenance intervals are not tolerated, thereare obviously increased requirements for visualisationby these embedded systems. Classic PC´s donot generally meet these requirements becausehard drives and ventilators cannot be used in aharsh industrial environment. This is where compact-flashmemory cards can be used due to theintegration of special processors and coolers whichdo not include any ventilators. Dust, dirt andmoisture are no problem thanks to the high frontside protection class.UMG 508EthernetUMG 511Areas of applicationUMG 604EIn the field of energy measurement technology and energy management, touch panels are used for the visualisation ofprocess and energy data at site. The communication takes place through two existing Ethernet interfaces in the JPC104,JPC121 and JPC150 models. The JPC35 has a RS485 or RS232 interface. The standard application for the visualisation ofup to 15 x UMG103 is available for all touch panels. Larger projects are possible upon request.JPC104 / JPC121 / JPC150 applicationThe 15”, 12” and 10” touch panels have a pre-installed Windows embedded operating system.These panels serve the purpose of visually presenting the web pages of individual UMG instrumentsusing a web browser (e.g. Firefox). The UMG 507, UMG 508, UMG 511,UMG 604 andUMG 605 can be configured with these web sites. In addition, the data is presented graphicallyand in tabular form. It is also possible to transfer customer-specific web sites. Customer specificapplications can also be produced upon request by Janitza electronics ® .JPC35 applicationThe 3.5” touch panels can be configured close to the application for various uses. It is, therefore, possible to display severalinstruments (e.g. UMG 96S and UMG 103) on one screen. The standard menu guide is designed intuitively.It is possible to view values from up to 31 instruments on one display.Specific applications such as configuration settings for the instruments, limit valuemonitoring, additional measurement values or measuring instrument headings canbe configured and parameterised upon request. The Modbus RTU communicationprotocol transfers the measurement value data. The RS485 and RS232 are availableas an interface for the JPC35.199
