Attachment:ArrayTag.JPG (81 Downloads) I don't know how to creat a new thread on this system. My question is related to this latest posting, so I'll continue from there... I cannot figure out how to address arrays in the S7-1200 for indirect addressing. I can compile if I stick a number in the index, but I want to use a variable. "Data_Block_1".a_array[1] works but "Data_Block_1".a_array[index] does not. a_array [0 .. 10] of DINT index is DINT Any suggestions. I'm out of ideas. Help tells me to select Properties and enable Multiplexing in the Inspector Window. But I have searched and searched and have no idea how to find this either.
