PLC, HMI, SCADA programmer

Обобщение на опита в програмирането на PLC:

1. Beckhoff Twincat 2 и 3: Използвах TwinCat 2 в ABB, където 50% от машините бяха разработени на базата на TwinCat2. Така че, за да върша работата си там като инженер по поддръжката, трябваше да познавам структурното програмиране.

In ABB I also developed an OEE systems. Again I used Twincat 2 for collecting signals from machines, send the with Functional block to MS SQL 2017 server and read and Visu them with Angular 4. So in the end I had one web based application for visu of OEE data in the production.
I used Twincat 3 in one project in Lamborghini where the first role was to make changes of existing programs in case of troubles and where improvement was needed.

1. ABB PLC. In ABB I had to develop a several programs with ABB Eco type controllers. Also In existing machines where improvement was needed for example screwing drives was giving errors or wrong screwing so changes was needed to improve the process, or welding machines where some additional function was requested from management to improve the welding process or add some additional function.

Troubleshooting of programmed PLC from India engineers, installed in Abu Dhabi. The plc was overloaded and was stopping to work. The task was to troubleshoot the problem and it was logical error in Ladder programing. The solution was to reprogram the existing FB with Structural text and start the process.

1. IFM Mobile PLC – developed programs for movable grinding machine in mining industry in Germany. The task were to use old PLC program written with IL to structured text. Add some new functions the machine to be controlled remotely with Remote control. In additional IFM HMI PLC was programmed for dashboard where show the rpm, oil level and temp, fuel, errors and warnings.

The most specific was to program the communication between engine and gear box, because the customer was ordered wrong engine specs and when it starts was in emergency state with 1200 rpm because of missing communication between engine and gearbox. The engine model was Deutz.

1. Siemens:

Programing conveyer system onsite in France – add level detection sensor Vega with analogue output to existing siemens configuration. Programing modbus tcp/ip communication to Schneider SCADA system.
Develop changes in grinding machine in bearing production.
Programing conveyers.

1. Wago codeys based PLC – 3 years programing of Solar plants control. Power management, MQTT data transfer from/to PLC with AWS server, Modbus RTU communication with power meters, solar inverters, sensors for sun radiation.
2. Събиране на данни от Arduino от електромери и изпращане до aws сървър с MQTT
3. Revolution PI, PLC с отворен код на Raspberry Pi, програмиране на смесване на течности в резервоара. Програмиране на PLC и уеб визуализация HMI.
4. Освен това програмиране на myScada, ABB, Siemens, базирани на codesys webVisu HMI и др.
