Glade Hal Meter Spindle Speed -> postgui

Hello,
iḿ still a beginner with glade and today i wanted to add a Hal Meter in Glade that shows the spindle speed. 
Things i did so far:
- I found out that i minimum require a float signal (maybe that on the picture attached?)
- i created a Hal Meter in Glade -> see attached file

I tried to add the call for gladevcp.Spindel in my machine.ini but didn't realize that Glade starts after the machine.ini

My next step was the postgui.hal
net Spindelrpm =>  gladevcp.Spindel <= spindle.0.speed-out
Error --> custom_postgui.hal:9: Pin 'spindle.0.speed-out' was already linked to signal 'spindle-vel-cmd-rpm'

Yesterday i learned that if a signal is linked i can´t use it.... but from here i don´t know further

Please help

You can assign names to signal pins and can use those names multiple times.

Unfortunately, I'm still stuck, even with the additional link.
My thoughts:
Where can I get the spindle speed (float)? Would that be the value “spindle.0.speed-out,” for example, which can be seen in the attachment?
How do I transfer the float value to gladevcp.Spindel?

My favorite code doesn't work.  Error "custom_postgui.hal:9: Pin 'spindle.0.speed-out' was already linked to signal 'spindle.0.speed-out'"
 

try changing

to

net Spindelrpm => gladevcp.Spindel
Got that... i just created the signal.name Spindel.rpm which is linked to gladevcp.Spindel.
There is still my problem where to get the float.out(?) from and link it to Spindel.rpm. My "favorite" spindle.0.speed-out is already linked -> Error "custom_postgui.hal:9: Pin 'spindle.0.speed-out' was already linked to signal 'spindle.0.speed-out'"

Sorry... German beginner

An output pin can only be connected to one signal, but a signal can be connected to many input pins.

You didn;t post your postgui file so can't see the actual problem to comment more.

In your hal file you have

So the signal spindle-vel-cmd-rpm can be connected to your rpm meter or you can comment out the line that pncconf made.

Difficult without seeing all your hal files so we really don't know what halpins is connected to what signal name but this:

nked -> Error "custom_postgui.hal:9: Pin 'spindle.0.speed-out' was already linked to signal 'spindle.0.speed-out'"

tells you that you have a line somewhere like this:
this will create a SIGNAL named 'spindle.0.speed-out ' to which you have connected the HALPIN named 'spindle.0.speed-out'

So you would need to change this:
to this

Note though that using halpin names for signal names is likely to create confusion.

Thatś it. Thanks

My custum_postgui.hat is now correct
#[Spindel]
net spindle-vel-cmd-rpm => gladevcp.Spindel1

I guess i really have some problems with reading signals in the machine.hal. I thought in my case "spindle.0.speed-out" give me directly my float value. Have to write a small manual for me.
