Creation of a Digital Twin and Its Control Based on the ANSI/ISA-S88 Standard
Holba, Jan ; Husák, Michal
This paper deals with development of detailed digitaltwin of small-volume liquid storage unit, as well as its completevirtual commissioning. The original design of the existing unit issubstantially modified to increase reliability and robustness. Thecontrol logic for PLC, according to ANSI/ISA-S88 standard, isalso created. Based on this implementation of the control logicfor the digital twin, its real counterpart will also be put intooperation.
Implementation of storage entity in S7-1200
Holba, Jan ; Benešl, Tomáš (referee) ; Husák, Michal (advisor)
This thesis deals with implementation of storage entity for small-volume liquid storage unit. It modifies current construction of existing storage unit and its method of liquid dosage, addressing numerous issues and ensuring greater unit reliability. Furthermore, it provides a characterization of the fundamental principles of Industry 4.0, the Self-Acting Barman testbed concept, and the ANSI/ISA-S88 standard. Both the storage unit and its control logic are based on this standard. Creation of a complex digital twin and its virtual commissioning in the MCD application of the Siemens NX program is described. Complete electrical schematics of the unit's wiring and as well as an operational manual for unit’s touch panel are also provided.
