[etherlab-users] Cannot generate voltage into Beckhoff analog output klemme

[Lazaros Penteridis]

Hello and happy new year,
I have installed ethercat master 1.5.2 and etherlab 2.1.0 on linux kernel
2.6.35.9 with rtai 2.1.0. Everything seems to have been installed correctly
since I got through the problems I faced on all the previous steps. Now I
try to implement a simple test case in order to measure voltages on the
outputs of my beckhoff klemme EL4004. For that I made a model on simulink
Matlab using etherlab_lib containing 4 constant voltage sources(to which I
give floating point values between 0-1) that are connected to the 4 inputs
of the klemme(i unchecked vector output but i have the same results even
when I give the values in vector form). I managed to get this model to
build and then I ran it. My circuit is composed of two klemmes, the EK1100
which is connected to two isolated power supplies, one 24V on it's power
supply and a second 24V supply on the plus and minus pins for the supply of
the other klemme, EL4004, that I want to control. When I run the executable
./"model_name" I get from the led code(on klemme EL4004 the first and the
third row of leds are continuously turned on) and from the sys log messages
that the klemmes are in the operational state, but when I try to measure
with an output with my multimeter I fail and I get 0 voltage. What am I
missing/ doing wrong here?
During the compilation of the model I get two warnings the first of the two
I managed to eliminate through adding the directory path into include
directories section of custom code on the configuration parameters of the
model I write them here in case they are related to the problem and they
are giving more information about it

*File ecrt_support.c associated with S-Function 'ec_slave3' (used in
'last_test/EL4xxx_0') does not exist*


*/vol/opt/etherlab/rtw/last_test_etl_hrt/rtmodel.h:24:0: warning:
"ONESTEPFCN" redefined [enabled by default]<command-line>:0:0: note: this
is the location of the previous definition*


Another problem that I face which I don't know if it's unrelated to the
previous or if it's a different aspect of the same problem is that when I
tried to make a reverse model than the one described above for input of
voltage in my pc using the analog input klemme EL3064 and 4 outputs the
model cannot compile and the output I get is the following when I press
build model:

I'm in a deadend now and after dozens of hours of searching on the internet
I didn't find anything helpful so any help would be appreciated.

Thanks in advance!
