If youΒve been future proofing your process infrastructure byspecifying smartђ field devices for instrument replacements and plant extensions, then you probably already have HART > instruments installed in the plant. But are you exploiting this considerable investment?HART ΢׆ up to four process variables fromeach HART > provides simultaneous analogue and digitaloperation so that the 4/20mA analogue signal can be connected to conventional I/O cards for control while the digital signal can be used for: > ή device ◆ device status ◆ instrument diagnostics ◆ configuration changesMTLs HART > Ү...

Things you may NOT know about HART > ή ◆ All HART > fi smart devices provide valuable data for process operations 24/7 - every second of every day. > ◆ Information on status (health) of the field devices and quality of the 4-20mA signals is in every communication. ◆ The Primary Variable is transmitted as a 4-20mA signal and alsoas a digital value. ◆ Many devices communicate Secondary Process Variables (measured or calculated) in addition to the Primary Variable. The HCF is an independent, not-for-profit organization funded byHCF membership & training/support fees. In addition the HCF: USING...
