RE: fanout is not working

Hi Phi,

 

You’re close, but I don’t think you can poke the motor record’s value into the dfanout that way.

 

One way you could do it is by processing the motor record, FLNK the motor record to the dfanout, and have the dfanout’s .DOL field set to the motor record’s .VAL field (NPP).  That may not be the exact solution but that’s the direction I would head.

Subject: fanout is not working

 

Hi,

 

I have created a virtual motor and can successfully use the `caput` and `caget` commands to set and read its value, respectively. However, my `dfanout` record is not moving the motors with relative motions as expected. I have confirmed that the motors respond correctly when I use `caput` to directly interact with the fields in `dfanout`.

 

record(motor, "$(P)"){

      field(DTYP, "Soft Channel")

      field(DESC, "Move Y,ib,ob,ds mtrs")

 

      # Where to write the setpoint to

      # Output to upstream, inboard and outboard motors

      field(OUT, "$(P)-F PP MS")

      field(PREC,"7")

....}

 

#Move Y motors ib,ob,ds in same direction

record(dfanout, "$(P)-F") {

    field(DESC, "move ib,ob,ds MTR")

    field(OUTA, "$(OUTBOARDMTR).TWF PP MS")

    field(OUTB, "$(INBOARDMTR).TWF PP MS")

    field(OUTC, "$(DOWNSTREAMMTR).TWF PP MS")

    field(PREC, "7")

 

Please advice.

Thank you,

Phi
