English	Numeric	English	Numeric
	Code		Code
TX_DLY	1005	1 to 500		TX DELAY—Configurable response-delay timer
		milliseconds		allows you to force the UDC to delay its response
				for a time period of from 1 to 500 milliseconds
				compatible with the host system
				hardware/software. This parameter is also used for
				the IR communications link.
WS_FLT	1006			Defines word/byte order of floating point data for
				communications. Byte values:
				0	1	2	3
				seeeeeee emmmmmmm mmmmmmmm mmmmmmmm
				Where:
				s = sign, e = exponent, m = mantissa bit
		FP B	0	0	1	2	3
		FPBB	1	1	0	3	2
		FP L	2	3	2	1	0
		FPLB	3	2	3	0	1
SDENAB	1007	DIS	0	SHED ENABLE—Disables/enables shed
		ENAB	1	functionaliy.
SHDTIM	1008	0 to 255		SHED TIME—The number that represents how
		Sample		many sample periods there will be before the
		Periods		controller sheds from communications. Each
				period equals 1/3 seconds; 0 equals No shed.
				Note: If ComSTA is set to MODBUS and if
				SHEDENAB is set to DISABL, Shed Time will not
				be configurable.
SDMODE	1009			SHED CONTROLLER MODE AND OUTPUT
				LEVEL—Determines the mode of local control you
				want when the controller is shed from the
				communications link.
		LAST	0	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.
		MAN	1	TO MAN—MANUAL MODE, SAME OUTPUT—
				The controller will return to manual mode at the
				same output level that it had before shed.
		FSAFE	2	FSAFE—MANUAL MODE, FAILSAFE OUTPUT—
				The controller will return to manual mode at the
				output value selected at Control prompt FAILSAFE.
