The ISA100.11a Working Group, under the ISA100 Committee, has officially begun its first letter ballot on its draft standard, the first in the ISA100 universal family of industrial wireless standards.

The ballot opened on Monday, 5 May, and will close on Tuesday, 3 June. ISA100.11a Working Group members may vote on the ballot and may provide
editorial or technical comments.

The ISA100.11a standard is designed to provide a wireless industrial process automation network to address control, alerting, and monitoring applications plant-wide. The standard focuses on battery-powered field devices with the ability to scale to large installations. It addresses wireless infrastructure, interfaces to legacy host applications, security, and network management requirements.
