Remote monitoring and control presents many challenges calling for creative solutions. Whether adding remote I/O to a legacy PLC, extending analog and digital monitoring to a remote plant, or connecting serial devices without creating new hardwired links, industrial users want solutions that are simple to implement, reliable and cost-effective. This paper considers the capabilities needed in wireless I/O products and suggests what is important in equipment, installation, and support.
Security within the data path and data content are not addressed within this article. This is a very important part of attemping to protect our infrastructure (i.e. control systems).
