The System Monitoring and Communication (SMAC) Profile defines a subsystem intended for integration into JAS nodes to provide control, communication, and state-of-health (SOH) monitoring capabilities. The SMAC subsystem consists of a single, common design applied to all nodes which provides a consistent interface to the system controller regardless of the type of node it is integrated with. This commonality eliminates the need to design specialized software routines to communicate with each node type.

System Monitor and Communication (SMAC)

The SMAC provides communication traffic to and from the node, including the following functions:

  • Network router for command and control
  • Control to read and drive discrete digital I/O and data buses
  • Configuration of node FPGA(s)
  • SOH reporting, including node temperatures, voltages, and currents
  • Local and neighboring node power control
  • Connectivity to personality NV memory
  • System timing synchronization
