Hello,

I have changed the file ec_slave3.c in two folders but still getting the
same error:

/vol/opt/etherlab/src/etherlab-2.1.0/rtw/blocks/EtherCAT/ec_slave3.c
> /vol/opt/etherlab/rtw/blocks/EtherCAT/ec_slave3.c

In MATLAB I can open the first one with the command ">> open ec_slave3.c"
and this is the new file.

When I open Beckhoff folder in the EtherLab library I get the
following messages in the command window from MATLAB:

Warning: Error reported by S-function 'ec_slave3' in
> 'etherlab_lib/EtherCAT/Beckhoff/EL3356_0':
> Variable context: PORT_CONFIG.output(1).pdo_data_type
> Unknown data type
> Warning: Error reported by S-function 'ec_slave3' in
> 'etherlab_lib/EtherCAT/Beckhoff/EL5021_0':
> Variable context: PORT_CONFIG.output(1).pdo_data_type
> Unknown data type
> Warning: Error reported by S-function 'ec_slave3' in
> 'etherlab_lib/EtherCAT/Beckhoff/EL51xx_0':
> Variable context: PORT_CONFIG.output(1).pdo_data_type
> Unknown data type


If I use the total rtw/blocks/EtherCAT folder from sourceforge instead of
my current folder there are no errors in the command window, but when I
compile the model the following error occurs:

Error in S-function 'untitled/EL2xxx_0': S-Function 'ec_slave3' does not
> exist


I hope this information gives a better picture of the problem, so it can be
solved.

Thank you in advance,
*Ralph Oosterveld*
