Block Device DeviceType Parameter 4 Background 4.1 Motivation In today’s automation systems, field devices from many different suppliers have to be integrated into the system, which results in additional effort for installation, version management and operation of these devices. This challenge is best met with an open and standardized device integration solution. Two different device integration technologies exist: the Electronic Device Description Language (EDDL) in accordance with IEC 61 804 and the Field Device Tool (FDT ® ) in accordance with IEC 62453. While these technologies take different approaches to solve the problem, there is a lot of overlap between them. This has led to a situation where the technologies compete instead of complementing each other. As a result, system suppliers have taken their positions, device suppliers have had to double their efforts in order to support EDDL and FDT ® , and the end users have become frustrated because they want the best of both technologies. For all parties involved, the ideal solution looks different. System suppliers want to achieve robustness while assuring a high level of technology and platform independence. Device suppliers want to support only one technology instead of two in order to reduce cost and effort, and they want to provide the optimal means for operating their devices. End users...
