This is a RobotStudio Smart Component to connect GI/GO to SIEMENS PLC using Snap7 library.

• Update ABB.Robotics.* References to Good RobotStudio SDK Version path with Project - Add Reference - Browse.
• On Project Properties:
  • Application: Choose good .NET Framework version.
  • Build Events: Post Build Events: Replace with the good LibraryCompiler.exe Path.
  • Debug: Start External Program: Replace with the good RobotStudio.exe Path This not work if project on network drive, let it clear.
• In \RSConnectGIOToSnap7\RSConnectGIOToSnap7.en.xml:
  • Replace xsi:schemaLocation value with good one.
• Same for \RSConnectGIOToSnap7\RSConnectGIOToSnap7.xml.

• In $(RobotStudioPath)\Bin\RobotStudio.exe.config file:
  • Add in section <configuration><runtime>
    • <loadFromRemoteSources enable="true"/>

• Start first RobotStudio to get RobotStudio.exe.config loaded.
• Then attach its process in VisualStudio Debug - Attach to Process..

• PLC_Addr:
  IP Address of PLC IPV4.
  For PLCSim, you have to run NetToPLCSim and enter PC IP.
• PLC_Rack:
  S7_300 Rack=0
  S7_400 See HW Config
  S7_12xx/15xx Rack=0
• PLC_Slot: S7_300 Slot=2
  S7_400 See HW Config
  S7_12xx/15xx Slot=1
• GI_ByteNumber: Number of Byte for GI to connect to in Station Logic.
  Change it to get GI appearing.
• GI_FirstByteAddress: First output byte to connect at GI.
  You can use: ABx QBx MBx DBx.DBBy
• GO_ByteNumber: Number of Byte for GO to connect to in Station Logic.
  Change it to get GO appearing.
• GO_FirstByteAddress: First input byte to connect at GO.
  You can use: EBx IBx MBx DBx.DBBy

• Connect: Start to connect to PLC.
  If an error occurs, you can check if it is related to Sharp7 or Snap7 in their Forum
• Read: Read GI on PLC one time. (Hidden if not connected)
  In simulation running, they are read continuously.
  GO are written each time they change.
