Process facilities in most industries have multitudes of HART devices monitoring processes throughout the plant. The challenge is getting all of the HART data from those instruments to the control systems and higher-level systems for predictive analytics while controlling costs and without running more wires.
A four channel HART to Ethernet gateway is a perfect device to serve as a remote HART I/O interface to MODBUS/TCP hosts by multidropping up to 16 HART devices per channel, 64 devices total. For maximum density, the HES HART to Ethernet Gateway System can be used to gather hundreds of HART variables from multiple devices and send over Ethernet. If diagnostic bits and bytes are included, the data points reach into the thousands for each HES. 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.
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
