Error Reporting
FS24XPlus™ implements HART® protocol Command 48, meaning that if any event is detected in the
detector while a HART® host is connected, it will be reported immediately. Therefore, warning
messages may pop up during other operations.
Connection
It is best to use a dedicated HART® interface point to connect a HART® master (primary or
secondary).
If such an interface is not available, it is possible to connect to HART® signal across a load resistor in
the current loop, point-to-point mode.
For example, provided there is the minimum resistance of 250Ω in the 4-20 mA loop, the
HART®handheld device can be connected across the terminals in the junction box.
CAUTION
If using multi-drop mode, the mA output cannot be used to provide a functional safety rated output
signal.
