S7 scl

I use Beckhoff, but we are converting a machine from Beckhoff to Siemens.

I'm trying to use SCL, because all our code is ST in Beckhoff.

How the he(double hockey sticks) do I get the outputs of an FB in SCL?

I've done this and it works

Reduce_MoveAbsolute(Axis := "ReduceAxisChar_DB".Axis,
Execute := TRUE,
Position := "PForm_DB".Step.ReducePosition,
Velocity := "PForm_DB".Step.ReduceVelocity,
Acceleration :=1000,
Deceleration := 1000,
Jerk := 0,
Direction := 0,
Mode := 0,
DoneFlag :=0);

bBusy := Reduce_MoveAbsolute.Busy;

BUT I'd rather do this

Reduce_MoveAbsolute(Axis := "ReduceAxisChar_DB".Axis,
Execute := TRUE,
Position := "PForm_DB".Step.ReducePosition,
Velocity := "PForm_DB".Step.ReduceVelocity,
Acceleration :=1000,
Deceleration := 1000,
Jerk := 0,
Direction := 0,
Mode := 0,
DoneFlag :=0
Busy := bBusy);
I've tried Busy => bBusy, and various combinations.

In case it's confusing, the FB has "Busy" for an output parameter (boolean), my bit is "bBusy" which is a boolean.

I thought I was doing it as the document says but it doesn't work.

If it's CoDeSys 2.x then use the "magic" key. F2.

Good Luck,

That would be F1 in Siemens .

What are you using? Simatic Manager or TIA? What PLC?

You've found the only way to use the outputs from FB's.

Reading fail.
I was afraid I missed something. Thanks.
It's a 315T-3 PN/DP, and you have to use SIMATIC Manager, Technology PLCs can not be programmed with TIA at this point.
I wish I was more conversant in Siemens, but I'm making my way through it, I still prefer my TwinCAT no offense Siemens peeps.


That user name is awesome L D[AR2,P#0.0].

did you declare it correctly?
as output or in/out
and not all versions can do it 300 can.
