2757 - 2757 10072 - 10072 Digital Input States UINT16 bit-mapped
-------- 22221111
Two nibble fields: (2222) for input#2 and (1111) for input
#1.
Lsb in each nibble is the current state of the input. Msb in
each nibble is the oldest registered state. 1
2758 - 2758 10073 - 10073 Digital Relay States UINT16 bit-mapped -------- --ab--cd If "a" is 1 then state of Relay#2 is unknown, otherwise state
of Relay#2 is informed in "c": (1=tripped, 0=released).
If "b" is 1 then state of Relay#1 is unknown, otherwise state
of Relay#1 is informed in "d": (1=tripped, 0=released). 1
2759 - 2759 10074 - 10074 Turn relay on UINT16 bit-mapped
