The second reg-ister indicates input/output state with bits 0 to 15 corresponding toinput/output state 17 to 32 (if required). The third register indicatesinput/output state with bits 0 to 15 corresponding to input/outputstate 33 to 48 (if required). The fourth register indicates input/out-put state with bits 0 to 15 corresponding to input/output state 49 to64 (if required).The number of registers required is determined by the specificdata item. A bit value of 0 = Off and 1 = On.F501UR_UINT16: LED STATUSLow byte of register indicates LED status with bit 0 representingthe top LED and bit 7 the bottom LED. A bit value of 1 indicatesthe LED is on, 0 indicates the LED is off.0 = Off, 1 = OnF502BITFIELD: ELEMENT OPERATE STATESEach bit contains the operate state for an element. See the F124format code for a list of element IDs. The operate bit for element IDX is bit [X mod 16] in register [X/16].F515ENUMERATION ELEMENT INPUT MODE0 = Signed, 1 = AbsoluteF516ENUMERATION ELEMENT COMPARE MODE0 = Level, 1 = DeltaF517ENUMERATION: ELEMENT DIRECTION OPERATION0 = Over, 1 = UnderF518ENUMERATION: FLEXELEMENT UNITS0 = Milliseconds, 1 = Seconds, 2 = MinutesF519ENUMERATION: NON-VOLATILE LATCH0 = Reset Dominant, 1 = Set DominantF522ENUMERATION: TRANSDUCER DCmA OUTPUT RANGE0 = –1 to 1 mA, 1 = 0 to 1 mA, 2 = 4 to 20 mAF523ENUMERATION: DNP OBJECTS 20, 22, AND 23 DEFAULTVARIATIONF524ENUMERATION: DNP OBJECT 21 DEFAULT VARIATIONBitmask Bank selection0 Card 1 Contact 1 to 41 Card 1 Contact 5 to 82 Card 2 Contact 1 to 43 Card 2 Contact 5 to 84 Card 3 Contact 1 to 45 Card 3 Contact 5 to 8Bitmask Default variation0 11 22 53 6Bitmask Default variation0 11 22 93 10
