Notes :
0,4-255: Mode0Analog input and analog output no correspondence , belonging to an independent state. Analog output value can be set via the PC communication .
1: Follow-up mode1 ,This mode analog output value can not be set by the host computer via the communication . Output value of1 : 1Follows the input value changes .
Note that if the input and output types, such as input is0-20mA, The output is0-10VThen enter10mAWill cause the output value is10V, The input will not further increase the output variation .
2: Follow-up mode2This mode analog output value can not be set by the host computer via the communication .
Set output= yEnter the= x, According to this modey = (8 * x) / 5 + 4Conversion .
Purpose is tox = 0To10Converty = 4To20.
3: Follow-up mode3This mode analog output value can not be set by the host computer via the communication .
Set output= yEnter the= x, According to this modey = (5 * x) / 8 - 2.5Conversion .
Purpose is tox = 4To20Converty = 0To10.
The user is not specified, the function does not provide a model 2,3 ,
