In order to be able to implement both the ModbusE acquisition cycle and the OPC UA server, the BeagleBone Black Board was chosen as the hardware platform. This board uses the Sitara AM335x processor (Texas Instruments (TI), Dallas, TX, USA) from Texas Instruments. Thus, the acquisition cycle was implemented on the PRU0 real-time core, and the OPC UA server, running under the Linux operating system, was implemented on the ARM Cortex A8 processor. From the analysis of the communication speed of the messages between the OPC UA client and the ModbusE servers, it was found that the ModbusE acquisition cycle speed was higher than the acquisition speed of the OPC UA client.<\/jats:p>","DOI":"10.3390\/s24072072","type":"journal-article","created":{"date-parts":[[2024,3,25]],"date-time":"2024-03-25T12:32:36Z","timestamp":1711369956000},"page":"2072","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Industrial Internet of Things Gateway with OPC UA Based on Sitara AM335X with ModbusE Acquisition Cycle Performance Analysis"],"prefix":"10.3390","volume":"24","author":[{"given":"Cornel","family":"Ventuneac","sequence":"first","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, Stefan cel Mare University, 720229 Suceava, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vasile Gheorghita","family":"Gaitan","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, Stefan cel Mare University, 720229 Suceava, Romania"},{"name":"Integrated Center for Research, Development and Innovation in Advanced Materials, Nanotechnologies and Distributed Systems for Fabrication and Control (MANSiD), Stefan cel Mare University, 720229 Suceava, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,24]]},"reference":[{"key":"ref_1","unstructured":"Zurawski, R.
