Hi, I am struggling getting the Hex protocol for Set commands right. Reading the Text protocol fine into a text String (array of 8 bit integers). But I cannot get the output right. Do I send the Hex message as a string? Do I convert the hexadecimal values per 2 to ASCII values? And compose the output string of these ascii characters? Using a CompactLogix PLC with a 1769-ASCII module. Thanks in advance for help
