Hello,
You need to create a byte array for the parameter.
So make a byte variable and name it something like array[5] where 5 is the number of bytes in the array.
You can then just use array as your parameter. i.e. without the square brackets.
5 * 8 allows you to control up to 40 coils.
Hope this helps.

Thanks for the reply,
i can fill in the VAR "array" now ( not array[2] ) in the component but the data output is not correct, i am missing the data from VAR "array"
wrong data : 2 15 0 0 0 8 0 .. 63 255 (from flowcode)
correct data: 2 15 0 0 0 8 0 7 127 84
the VAR array[2] var is working in another component
