Data Logging on PC from HART Supported Devices

02/29/2012 4:56 AM

Hi,

we have 11 Mass Flowmeters from Krohne and 9 from KOBOLD and both uses HART Protocol to communicate.

I want to maintain a data log on a PC from all 20 meters. I found that one achieve it by just installing a HART Multiplexer and PACTWARE on PC. But the problem is that KOBOLD devices support Siemens PDM only. How can I integrate all 20 meters on a single PC?

Each Vendor's Pactware is modified by the vendor. The vendor who supplies Pactware software determines how it handles brands other than its own brand. Sometimes a license has to be purchased to do anything other than the generic HART instructions.

I was unaware that Pactware could datalog. If so, the datalogging function in Pactware might require licensing for brands other than the vendor's brand of HART instruments.

If you want to use Pactware, you need to inquire of the Pactware vendor as to the feasability of getting Kobold instruments to datalog with Pactware.

Datalogging is what HMI software does, products like Wonderware, iFix, Indusoft, Citect, WinCC, etc. or whoever's control hardware you use (all control vendors have their own HMI software).

HMI software fetches data from the controller(s) you have the flowmeters connected to via industrial protocols like Modbus, Profibus or OPC. I'm not sure that any of the HMI's uses HART from HART multiplexors, but you can ask if you go down this route.

Sir,

If your problem resolves itself into a communications protocol mis-match, there are vendors of protocol converters that can have up to 4 ports all talking different protocols at different speeds. One I have used in the past is Miille in Houston TX. --JMM
