Design and Functional Principle<br />
2.5.3 HART-function<br />
Function<br />
The positioner is also available with built--in HART-functions. The<br />
HART protocol allows you to communicate with your instrument with a<br />
handheld communicatorR, PC or programming unit. This enables you<br />
to configure your instrument comfortably, save configurations, call diagnostic<br />
data, display online measured values and much more. Communication<br />
takes place as frequency modulation over the existing signal<br />
lines for the command variable from 4 to 20 mA.<br />
The SPART PS2 is integrated in the following parameterization tools:<br />
S Handheld communicatorR<br />
S<br />
S<br />
S<br />
PDM (Process Device Manager)<br />
AMS (Asset Management System; update in preparation)<br />
Cornerstone<br />
. NOTE<br />
Operation on the positioner has priority over the settings via the HART<br />
inetrface.<br />
Communication is aborted by a power failure at the positioner.<br />
2.5.4 Alarm module<br />
Function<br />
The alarm module contains<br />
S 3 digital outputs and<br />
S 1 digital input<br />
The digital outputs serve to output fault messages and alarms. The<br />
configuration is described in chapter 4.4, page 85, with the parameters<br />
44 to 54.<br />
By an external signal applied at digital input (DI2) the actuator can be<br />
blocked or driven to its limit positions for example depending on the<br />
configuration. The configuration is described in chapter 4.4, page 85,<br />
with the parameters 43.<br />
The alarm module is available in two versions:<br />
S explosion protected for connecting to switching amplifier DIN 19234<br />
S non--explosion protected for connection to voltage sources with a<br />
maximum 35 V<br />
The semiconductor outputs of the alarm module report an alarm (signal<br />
state Low) by switching off with high resistance. They are conductive in<br />
the High state (without alarm). The <strong>dyna</strong>mic <strong>control</strong> makes them error<br />
self--reporting.<br />
