Single Channel HART to Ethernet Gateway

Process facilities have a significant investment in the BPCS (Basic Process Control System) and upgrading with new HART capable input cards or a new control system in order to get HART data from newer smart HART devices is often cost-prohibitive. But they still need to get HART data from key devices to optimize their process. Plus, with expanding analytics capabilities of higher-level systems and the spreading adoption of IIoT, a way is needed to get that valuable data where it can be factored into predictive analytics.

In this example the BPCS MODBUS/TCP host for the process does not have any smart HART input cards. This existing point-to-point 4-20mA process loop uses a single channel HES HART to Ethernet Gateway System to extract HART data from a smart HART flowmeter, converts it to MODBUS/TCP and reports it to the BPCS over Ethernet, without any BPCS upgrades. Additionally, any remote computer connected to the corporate network can view any data such as diagnostics and process variables gathered by the HES via a standard web browser. 

Key attributes:

HES can poll for:

  • Dynamic Variables (PV, SV, TV and QV)
  • 128 Device Variables from HART 7 devices
  • 25 Bytes of diagnostic data (Command 48) in addition to the above variables
