Fetch and Write

Fetch/Write is a protocol to communicate with a Siemens PLC. If you are using a Siemens 1200 or 1500 series PLC, you will need to grant Experior full access through TIA.

As part of the basic psychics model example guide, we show how to use the Siemens Fetch and Write protocol to test the model.

Properties for Fetch

• Identification
  • Name – Customizable name
  • Id – Customizable Id
• Communication
  • Port – Port used for communication between Experior and “Device”
  • IP Address – Type in IP address (only available if Mode = Client)
  • Mode – Select “Server” or “Client”
  • Source – Choose the data area to be read from. Options are Flag Area(M), Input(I), Output(Q), Data Block(DB), Counter Cells(C) or Timer Cells(T)
  • Update Interval – Measured in milliseconds. Less than 25ms activates fast mode updating
  • Auto Connect – Activate or Deactivate whether Experior should try to automatically connect to the “Device”
• Memory Allocation
  • Automatic – Activate or Deactivate automatic memory allocation
  • Length – Set data length (only available if Automatic = False)
  • Offset – Set offset for data (only available if Automatic = False)

Properties for Write

• Identification
  • Name – Customizable name
  • Id – Customizable Id
• Communication
  • Port – Port used for communication between Experior and “Device”
  • IP Address – Type in IP address (only available if Mode = Client)
  • Mode – Select “Server” or “Client”
  • Destination – Choose the data area to be written to. Options are Flag Area(M), Input(I), Output(Q), Data Block(DB), Counter Cells(C) or Timer Cells(T)
  • Synchronized – Activate and Deactivate synchronisation
  • Auto Connect – Activate or Deactivate whether Experior should try to automatically connect to the “Device”
• Memory Allocation
  • Automatic – Activate or Deactivate automatic memory allocation
  • Length – Set data length (only available if Automatic = False)
  • Offset – Set offset for data (only available if Automatic = False)
