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
