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 LEDs
When this bit is set, the LEDs are used for HART diagnostics. LED behavior
changes to show communication on HART with each LED representing a
HART loop. A flashing yellow LED indicates that communication is currently
being processed while a solid yellow LED 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.
50/60 Hz Filter
The values are:
• 0 = 50 Hz (default)
• 1 = 60 Hz
