Posted 26 Oct 2018 Hello: Im new on this foroum, and Im glad to become a member, and new on the Sysmac studio too . I have the following ST program line: My_array[0]:= y[0]; Where My_array, is a array of bool, and y array too. After load and all, on monitoring return a "!" Sign, and trying to change value retuns "Failed to write variable, check if variable or memory area are alloed to write". I tried to move both arrays from global to local, and change adressing in "AT" field, witout changes. Any help will be wellcome. Thanks in advance Dante Share this post Link to post Share on other sites
