欽一 北野, Shûji Yamamoto · 2014
From the beginning, Yokogawa has been participating in standardization and dissemination of ISA100.11a, a wireless communication standard for industrial automation advocated by the International Society of Automation (ISA), and has been expanding its product portfolio with conformance to this standard. Although field wireless standards including ISA100.11a are being introduced into plants widely, security is still one of the major concerns. This paper introduces the security measures of ISA100.11a and Yokogawa’s efforts to enhance plant security.
