Simple Code Examples

C#

// Declare using statement  
 using SIS7 = AutomatedSolutions.ASCommStd.SI.S7;  

// This function creates all required ASComm objects, sets initial properties, performs a write and read, then disposes the ASComm objects.
void SimpleReadAndWrite()  
{  
   // Create a Channel, Siemens channels have no settable properties  
   SIS7.Net.Channel myChannel = new SIS7.Net.Channel();  

   // Create a Device: S7-1200 CPU at IP Address 192.168.0.121, rack 0, slot 2  
   SIS7.Device myDevice = new SIS7.Device("192.168.0.121,0,2", SIS7.Model.S7_1200);  

   // Create a Group with active flag set to false (no background scanning).   
   SIS7.Group myGroup = new SIS7.Group(false, 500);  

   // Create an Item: hardware tag name (data block) = 'DB3.DBB4', elements = 1, data type = byte  
   SIS7.Item myItem = new SIS7.Item("DB3.DBB4", 1, DataType.BYTE);  

   // Add device to channel  
   myChannel.Devices.Add(myDevice);  
   // Add group to device  
   myDevice.Groups.Add(myGroup);  
   // Add item to group  
   myGroup.Items.Add(myItem);  

   //Write one tag  
   try  
   {  
     // Perform a write with value from text box  
     myItem.Write(textBoxItemWrite.Text);  
   }  
   catch (Exception ex)  
   {  
     // Error occurred, implement error handler  
   }  

   // Read one tag  
   try  
   {  
     // Perform a read, save value to text box  
     myItem.Read();  
     textBoxItemRead.Text = myItem.Values[0].ToString();  
   }  
   catch (Exception ex)  
   {  
     // Error occurred, implement error handler  
   }  

   // Dispose channel at application shutdown  
   myChannel.Dispose();  
 }
