44、017 ISA. All rights reserved. 4 Industrial networks 4.1 Overview Industrial wireless communication systems often consist of a wide variety and number of diverse wireless networks making management a challenge. The industrial automation industry could benefit from a CNM that extends over other networ
45、k managers in the facility. 4.2 Current situation Today many industrial facilities have a multitude of wireless networks, both proprietary and standards based, working autonomously to fulfill specific automation needs. It is expected that the numbers of unique wireless networks and the numbers of ne
46、twork devices will continue to grow; however, since the spectrum is not growing, these networks will increasingly compete for a common frequency band. Each of these networks typically has unique network management devices, protocols, and metrics. As the number of networks and the size of those netwo
47、rks grow, the complexities of managing all of these networks may overstrain existing network management staffing and could often tend to favor one network over another for given shared resources. Additionally, the guidance from many wireless network vendors does not take into account the characteris
48、tics of the other wireless networks in use. The method to resolve conflicts would typically be to turn off the other wireless network or move it out of range rather than a deeper understanding of how to modify the characteristics of all wireless networks to coexist in a coordinated manner. An automa
49、ted coexistence management concept to use the spectrum efficiently is specified in IEC 62657-1. Further information on these types of issues may be found in IEC 62657-2 . Finally, unique security requirements for many wireless networks require the operators to understand all security procedures of each network. Mobile devices often are not allowed to participate in multiple networks due to lack of shared network concepts of authority, authenticity, etc. 4.3 Challenges 4.3.1 General challenges to industry In todays manufacturing and processing operations, opera
