When configured for N2, N2-capable equipment controllers conform to N2 field bus networking standards. When using an N2-capable equipment controller to replace a legacy N2 controller on an N2 field bus, you can expect the same network performance. However, if the installation’s existing N2 network is already heavily loaded or is frequently reporting off-line devices, then you should take steps to improve the network performance before replacing legacy N2 controllers with N2-capable equipment controllers. Refer to the N2 Communication Technical Bulletin (LIT-636018) and follow all N2 field bus networking rules, including those for the following instances:

  • Segment and total line length
  • End-of-line terminations
  • Number of devices per segment, between repeaters
