milliseconds compatible with the host system
hardware/software.
Defines word/byte order of floating point data for
communications. Byte values:

SHED ENABLE—Disables/enables shed
functionaliy. Applies to Modbus protocol only.
SHED TIME—The number that represents how
many sample periods there will be before the
controller sheds from communications. Each period
equals 1/3 seconds; 0 equals No shed.
Note: If ComSTATE is set to MODBUS or MB3K and
if SHEDENAB is set to DISABL, Shed Time will not
be configurable.
SHED CONTROLLER MODE AND OUTPUT
LEVEL—Determines the mode of local control you
want when the controller is shed from the
communications link.
LAST—SAME MODE AND OUTPUT—The
controller will return to the same mode (manual or
automatic) at the same output level that it had before
shed.
TO MAN—MANUAL MODE, SAME OUTPUT—The
controller will return to manual mode at the same
output level that it had before shed.
FSAFE—MANUAL MODE, FAILSAFE OUTPUT—
The controller will return to manual mode at the
output value selected at Control prompt FAILSAFE.
TO AUTO—AUTOMATIC MODE, LAST SP—The
controller will return to the automatic mode and the
last setpoint used before shed.
