Hi guys, could you help me? I'm trying to build a SCADA using LabVIEW DSC, NI OPC Servers and a S7-300 (w/ Serial MPI). I already downloaded the program and it works! The OPC channel is correctly working too. But when I try to WRITE data via OPC in a memory bit, the value does not retain. My program consists in an OB1 calling 4 FCs. In each one, there is a MOVE and a SCALE whose result is written on memory for reading by an OB35. The program can be found attached and the memory bit that I'm trying to write is the ENABLEs of the blocks inside FCs. Thanks, Bruno AttachmentControle.zip (187 Downloads) |

Hello, see the FAQ if the variables in data blocks or marker, timer and counter should be retain after a voltage interrupt: http://support.automation.siemens.com/WW/view/de/620566 With best regards |
