42. SAFE: Safe position
Only when 43.BIN is set to be ON, Safety valve is effective
If binary input is 0, valve will be drive to the position specified by this value.
43. BIN: Digit input functions
Enable/disable safe position function.
44. DO1: Digit output function 1
When positioner detected set fault, channel 1(DO1) of binary output module state is "high".
45 SW1: DO1 set value
When DO1 = LSET, valve position is less than the SW1, channel 1(DO1) of binary output module state is "high".
When DO1 = HSET, valve position is greater than the SW1, channel 1(DO1) of binary output module state is "high".
46 DO2: Digit output function 2
When positioner detected set fault, channel 2(DO2) of binary output module state is "high".
47 SW2: DO2 set value
When DO2 = LSET, valve position is less than the SW2, channel 2(DO2) of binary output module state is "high".
When DO2 = HSET, valve position is greater than the SW2, channel 2(DO2) of binary output module state is "high".
48 AMIN: Min output current.
Min output current for the 0% position.
49 AMAX: Max output current.
Max output current for the 100% position.
50 ADIR
Relation between the output current of position feedback module and valve position. There are two choices: rise
and fall. When choosing rise, output current will be 4mA when valve position is 0%; output current will be 20mA
when valve position is 100%. When choosing fall, the result will be opposite.
51 PROT: Write project for HART
When PROT = ON, write parameter is allowed by PC or field communicator with HART protocol.
When PROT = OFF, write parameter is not allowed by PC or field communicator with HART protocol.
