Fieldgate FXA520 was developed for remote monitoring of field devices with HART or 4...20mA interface, regardless of location. GPRS technology is used for wireless communication via the worldwide GSM mobile communications network. In addition, Fieldgate FXA520 can be used as a HART/Ethernet gateway in local networks. Fieldgate FXA520 contains an integrated Web server offering data logging and alarm management functions. Typical applications are remote monitoring of tanks and silos as well as remote parameterization and diagnosis of HART field devices (CommDTM).
