Re: [foxboro] 1-5ma input on a FBM201

 Yes I see strange..

  Anyway what about the EXTBLK parameter can it be tied to a CHARC block an=
d set the scaling there? or will I end up with no Bad, OOS or Error status =
bit being set when the real measurement goes way above 5mA (say 6mA).

EXTBLK
Extender Block is a long input that specifies the pathname to the BLKSTA
parameter of a CHARC block used as an extender block. The CHARC
block must be in the same CP and compound as the AIN block and must
precede it in the compound.

Thanks

Peter

IOMOPT equals 0 - the input should be in counts (0-64000 for normal
range)
IOMOPT equals 2 - the input should be in engineering units


0 is used in the first example for the second block.
2 is used in the second example for the second block.


For some reason or another an equals sign followed by a number gets a 3D st=
uck in between.

So, if I type =3D3D,1

You see =3D3D, 3D, 1

Equals signs are also inserted if there is a blank at the end of a line.

Strange, but true.

Hi Alex

        I am sorry but I don't recognize the IOMOPT options that you specif=
=3D3D ied below (3D1, 3D0, etc.) maybe the list server is doing something w=
eird d=3D3D o to the font that you are using?

        Are there more options for IOMOPT than the standard 0,1,3 ?

Thanks

Peter

Peter,

It seems to me that you could do it with two AINs. I think there are two ap=
=3D3D proaches that would work, but I can't try them. As they said in my ol=
d math=3D3D  texts, the proof is left to the student. :)


Option 1 - Scaled counts
Create two AINs. The first has IOMOPT=3D3D3D3D1 and is used to read your ph=
ysic=3D3D al input. Use the scaling factors on the block to change the raw =
counts so =3D3D that whatever you get at 5ma is scaled to 64,000.

Connect that block's output to the MEAS of the second AIN (IOMOPT=3D3D3D3D0=
). I=3D3D  think it will behave as you desire.


Option 2
Create two AINs. The first has IOMOPT=3D3D3D3D1 and is used to read your ph=
ysic=3D3D al input and scale 0-5ma as you want it in engineering units.

The second AIN would have IOMOPT=3D3D3D3D2 and take in that measurement. If=
 you=3D3D  set the scales properly, I think the OSV/BAD will kick in.


Of course, free advice is worth what you pay for it. :)

 =3D3D3D

Gentlemen:
        I am trying to use a FBM201 to measure 1-5ma input.

        I am using an AIN & can scale the output to read 0-100% for 1-5ma i=
=3D3D n however I don't get the OOS/BAD i/o bits set when I go over/under t=
he OSV

        The AIN block doesn't have a SCI for:  Linear 3200 to 1600 ( 1 to 5=
=3D3D
 mA)

        Is there any way to set the raw counts scale in the AIN block manua=
=3D3D lly?


Thank You,
