Is it possible to map array element to a EtherCAT Slave variable. I am trying to communicate with a EtherCAT HMI to read the floating variable. So I need to convert them in codesys from udint to real using arrays and union. I am trying to do with array. But I can't able to map them in I/O Mapping to EtherCAT Slave. Is there anyway I can map the array element to the EtherCAT HMI Variable?.

Hi TURCKONE
Thank you for your response. It helps me. I am using 256 bytes of read and 256 bytes of write with float as data type.
I was trying to upload my project. It took long time and not successful.

hello ,
you can use for loop to transfer entire array from one to another
for i=0 to 10
ethecat_variables_array[i]=your_array_you_want_to_copy[i];
end_for
My problem is I can't able to map the array elements to ethercat variables
is it possible to attach program?
how many ethercat variables you need to convert?
define array in variables list like :
CH0_RX_Array_Eth AT %QB210: ARRAY [0..29] OF BYTE;
