UR_UINT16 PACKED BITFIELD
First register indicates I/O state with bits 0(MSB)-15(LSB) corre-
sponding to I/0 state 1-16. The second register indicates I/O state
with bits 0-15 corresponding to I/0 state 17-32 (if required) The
third register indicates I/O state with bits 0-15 corresponding to I/0
state 33-48 (if required). The fourth register indicates I/O state with
bits 0-15 corresponding to I/0 state 49-64 (if required).
The number of registers required is determined by the specific
data item. A bit value of 0 = Off, 1 = On
F501
UR_UINT16 LED STATUS
Low byte of register indicates LED status with bit 0 representing
the top LED and bit 7 the bottom LED. A bit value of 1 indicates
the LED is on, 0 indicates the LED is off.
F502
BITFIELD ELEMENT OPERATE STATES
Each bit contains the operate state for an element. See the F124
format code for a list of element IDs. The operate bit for element ID
X is bit [X mod 16] in register [X/16].
