Technical Information
Fieldgate FXA320, FXA520
Gateways / Interfaces
Gateway for Remote Monitoring of Sensors and Actuators
via Web Browsers
Application
Fieldgates enable remote monitoring of connected 4...20
mA sensors/actuators, either via telephone lines
(analogue), Ethernet TCP/IP or mobile communications
(GSM). The measured data is web compatible (HTTP,
HTML, WML) and can, therefore, be analysed in the
web browser without additional software.
For remote diagnosis and remote configuration, HART
sensors are suitable in conjunction with FXA520.
Their integrated time control make Fieldgates suitable for
all applications in which more distant measuring points
have to be sporadically analysed. Configurable
monitoring of limit values with alarm signalling via e-
mail or SMS make it possible to react directly to changes
on-site.
The supported data transfer in XML format allows for
simple further analysis and processing of the measured
data, through to integration into complex planning
systems.
