AO<br />
Analog OP: (25 ms update)<br />
0-100% value is received from the<br />
C-200 and then converted to the<br />
equivalent 4-20 mA value.<br />
The following <strong>HART</strong> device digital data can be cached on<br />
the AI and AO Module and will then available for use within<br />
the system:<br />
� Device ID information: (#)<br />
Tag, Manufacturer, Model, SW/HW Rev, SN, date,<br />
descriptor, Etc.<br />
� Dynamic variables: (+)<br />
Command 3 (PV, SV, TV, FV)<br />
� Device variables: (+)<br />
Command 33, Slot-0 through Slot-3<br />
� Range information: (#)<br />
Range Hi and Range Low<br />
� Device standard status: (+)<br />
General device condition, command and comm status<br />
� Device-Specific status: (*)<br />
Command 48, Device-Specific status<br />
(#) Scanned at start-up or loss of communication<br />
