2-20 Configurable FLEX I/O Analog Module Features
Secondary Master Enable (SME) and Primary Master Inhibit (PMI)
These two bits control a few module internal functions individually for
channels 0 to 7.
HART Status Indicators
When this bit is set, the indicators are used for HART diagnostics. indicator
behavior changes to show communication on HART with each indicator
representing a HART loop. A flashing yellow indicator means that
communication is currently being processed while a solid yellow indicator
means that this device is in the transmitter list.
HART Status Inhibit
When this bit is set, the HART communication status is not shown in the
realtime data table to enable compatibility. The appropriate areas are cleared
with zeroes.
50 or 60 Hz Filter
The values are:
• 0 = 50 Hz (default)
• 1 = 60 Hz
