Rt.ResultCode = PLCClient.DBRead(DataBlockNumber, CaptureIndex, 256, rt.MemoryByte) Ĭonvertedvalue = .GetString(rt.MemoryByte) if (this.State = PLCClientConnectState.Connected) For the current application, I was writing a simple function block to broadcast data to a Red Lion serial slave display, but there are a variety of situations in which you may need to do to this, such as communicating. ReadDataBlockString_Result rt = new ReadDataBlockString_Result() Today, I found myself setting up some simple point-to-point serial communication on a Siemens S7-1200. public ReadDataBlockString_Result ReadDataBlockString(int DataBlockNumber, WRFDB: Write value indirectly to an F-DB (STEP 7 Safety V14) (S7-300, S7-400).
