External Switch Requirements

To meet the minimum requirements for successful operation with FieldDAQ devices, any switch directly connected to the FieldDAQ device should be compliant with IEEE 802.1Q bridges and bridged networks.

To take advantage of the network synchronization and network redundancy features of the FieldDAQ device, ensure that your network infrastructure meets certain requirements:

• IEEE 802.1AS-2011 time-based synchronization support—Automatically synchronizes timebases and enables the use of time-based triggers and multi-device tasks between device across the network.
• IEEE 802.1Q (Rapid Spanning Tree Protocol) support—Supports network redundancy functionality in ring and star topologies
  • Rapid Spanning Tree Protocol (RSTP) enabled
  • Bridge Protocol Data Units (BPDU) Guard disabled
