UR_UINT16: PACKED BITFIELD
First register indicates input/output state with bits 0 (MSB) to 15
(LSB) corresponding to input/output state 1 to 16. The second reg-
ister indicates input/output state with bits 0 to 15 corresponding
to input/output state 17 to 32 (if required). The third register indi-
cates input/output state with bits 0 to 15 corresponding to input/
output state 33 to 48 (if required). The fourth register indicates
input/output state with bits 0 to 15 corresponding to input/output
state 49 to 64 (if required).
The number of registers required is determined by the specific
data item. A bit value of 0 = Off and 1 = On.
0 = Off, 1 = On

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.
0 = Off, 1 = On
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].
