We are happy to schedule the ISA Communications Division (COMDIV) ISAConnect Live "Tech Talk" with Victor Wegelin. You are welcome to invite your peer professionals by forwarding the registration link to them. The meeting will be held in an open Town Hall Q&A format discussing, among other topics, the most relevant details associated with industrial wireless systems (based upon the ISA Training course IC85C) with an emphasis towards how the various technological choices coexist, interoperate, and interact with each other. Numerous examples of real-world deployments are covered for facilities such as supervisory control and acquisition (SCADA) systems, petrochemical plants, electrical power generation, and transmission systems. The operational differences posed to the wireless system's performance by discrete manufacturing needs, monitoring of devices, and even control systems are addressed. Considerable emphasis is placed specifically on ISA100 (the standard for industrial wireless) including deep dives into some of the standard's most pertinent details.
