[etherlab-users] Problems using Beckhoff EL3162 with Etherlab Simulink blockset - does not switch from PREOP to OP

[Sebastian Rehberger]

Dear Mr. Hacker,

Thank you for your immediate response. Indeed the slave is Revision EL3162-0000-0000 and rather old (2005).
I generated the .m file with "--skin" option, the modified result is attached below. I simply added the function head.

I tried the generic slave block and added ['el3162.m'] to the Struct Configuration field in the mask. 
However it compiles/checks diagram without error, but the block does not add outputs or changes its mask description in Simulink.
After running the executable again, the slave stays in PREOP without error flag - so I guess the slave block does not work properly. Have I missed a step?

Besides, I ran a test with CoDeSys where the EL3162 seems running properly.

Kind regards,
Sebastian Rehberger


% Slave configuration
function rv = el3162()
rv.SlaveConfig.vendor = 2;
rv.SlaveConfig.product = hex2dec('0c5a3052');
rv.SlaveConfig.description = 'EL3162';
rv.SlaveConfig.sm = { ...
    {0, 0, {
        }}, ...
    {1, 1, {
        }}, ...
    {2, 0, {
        }}, ...
    {3, 1, {
        {hex2dec('1a00'), [
            hex2dec('3101'), hex2dec('01'),   8; ...
            hex2dec('3101'), hex2dec('02'),  16; ...
            ]}, ...
        {hex2dec('1a01'), [
            hex2dec('3102'), hex2dec('01'),   8; ...
            hex2dec('3102'), hex2dec('02'),  16; ...
            ]}, ...
        }}, ...
    };

% Port configuration

rv.PortConfig.output(1).pdo = [3, 0, 0, 0];
rv.PortConfig.output(1).pdo_data_type = 1008;

rv.PortConfig.output(2).pdo = [3, 0, 1, 0];
rv.PortConfig.output(2).pdo_data_type = 1016;

rv.PortConfig.output(3).pdo = [3, 1, 0, 0];
rv.PortConfig.output(3).pdo_data_type = 1008;

rv.PortConfig.output(4).pdo = [3, 1, 1, 0];
rv.PortConfig.output(4).pdo_data_type = 1016;

Hi,

you may be using an old version of the slave. What version are you using? (ethercat slave -v -p?)

You will need to use the generic slave in this case. Run the following command ethercat pdos -pX --skin etherlab and save it in el3162.m. Then insert this function for "EtherCAT Slave Configuration struct".

Attached is a function I used for another slave. You may use it for comparison.
