Hello all. I am tryting to access data registers D121000 through D121530. does anyone know if this is possible? And if so, what is the proper syntax for this? For instance: a serial number I wanted to reference was 18 characters long starting at D1235 and I had no problems with this ns=1;s=[TAAAU00001\_Mitsubishi\_Q\_Ethernet]w1235 Now when I am trying to reach a 4 character string starting at D121000 neither of these options work: ns=1;s=[TAAAU00001\_Mitsubishi\_Q\_Ethernet]D121001 ns=1;s=[TAAAU00001\_Mitsubishi\_Q\_Ethernet]D121001 Please advise! TIA ---

Support for addressing beyond address 65535 got added in Ignition 8.1.47. Sounds like you’ll need to upgrade. ---
