Re: ASLO doesn't work

[李刚 via Tech-talk <tech-talk at aps.anl.gov>]

Hi Vishnu，

If DB6.DBD36 is not float，you must set DLV and DHV in INP field,and discard "float" parameter.
record(ai, "AI0") {

    field(DTYP,"s7nodave")

    field(INP,"@lcpcPLC(DLV=0,DHV=27648) DB6.DBD36 ")

    field(LINR,"LINEAR")

    field(HOPR,"20")

    field(LOPR,"0")

    #field(ASLO,"0.001")

    field(PREC,"4")

    field(SCAN,"1 second")

    field(EGU,"Bar")

    field(EGUF,"20")

    field(EGUL,"0")

}

If DB6.DBD36 is float and you set explicit in INP field  ，it will ignore all conversion just as Ben said

record(ai, "AI0") {

    field(DTYP,"s7nodave")

    field(INP,"@lcpcPLC DB6.DBD36 float ")

    field(HOPR,"20")

    field(LOPR,"0")

    field(PREC,"4")

    field(SCAN,"1 second")

    field(EGU,"Bar")

    field(EGUF,"20")

    field(EGUL,"0")

}

Cheers

Gang

主题: ASLO doesn't work

Hi,

I have tried to divide the value of ai record using ASLO field. But It doesn't work.

record(ai, "AI0") {

    field(DTYP,"s7nodave")

    field(INP,"@lcpcPLC DB6.DBD36 float")

    field(LINR,"LINEAR")

    field(HOPR,"20")

    field(LOPR,"0")

    field(ASLO,"0.001")

    field(PREC,"4")

    field(SCAN,"1 second")

    field(EGU,"Bar")

    field(EGUF,"32767")

    field(EGUL,"-32768")

}

my input is 1003.124 and it gives same only even i change ASLO to 1.

The PLC the value is 1003.124 in mBar, i have to display as 1.0031 Bar.

I am missing something to set.

Thanks

Vishnu
