Why is no connection set up from the operator panel to the controller via interface IF1 A (IF1 B) (IF2)?

  • Entry
  • Associated product(s)

With operator panels which use the serial interface for project transfer and also for communication with the controller, no connection is set up.

The system message "No. 220008 Interface IF 1A (IF 1B) (IF 2) cannot be opened" appears in the alarm display configured or in the message window.

If one of these interfaces is also to be used for communication, then you must disable the "Remote Transfer" option in the Transfer Settings of the Control Panel.

Below are instructions for making the setting in the following devices:

You must select the Transfer mode explicitly for another project transfer.

The following drives are concerned:

  • Allen Bradley DF1
  • Allen Bradley DH485
  • GE Fanuc  
  • LG Glofa-GM
  • Mitsubishi FX
  • Mitsubishi Protocol 4
  • Modicon Modbus
  • Telemecanique Unitelway
  • Omron Hostlink / Multilink
  • SIMATIC 500/505 serial
