Mesh Topology in ISA100.11a

Overview:

Analysis of the Mesh Topology in ISA100.11a D2.

Before a network can be used it must be formed. As part of this formation, devices must be provisioned with a network ID and a join key. The network ID is used to associate a device with a network and the join key is used to protect the device as well as the network during the join operation. Provisioning devices can be done by the manufacturer, in the maintenance shop, or in the field. In the D2 draft neither the requirements for nor the actual physical interface for provisioning has been specified.
