Remote controlled (driven by Digital Output register)
uint16 Digital I/O input setup 40082 0 R/W 0,1
Valid only when Digital I/O selection is set to Input (0) -
0=Reference only (status appears in 40013 and does
nothing else), 1=Override (status appears in 40013 and
valve plug is moved to safe position noted in register
40050)

1. uint is defined as unsigned integer
uint16 – unsigned 16 bit variable, can take value 0-65535.
uint32 – unsigned 32 bit variable, can take value 0-4294967295.
(Reserved) – registers used for development use only.
† - 32bit register contains data that spans two registers – reads and write of data needs
to be performed within the same Modbus command function to ensure coherency of
data.
