Note
As far as operator panels are concerned, the hand-held barcode readers operate as keyboards. To read a value into an operator panel, you must put the focus on an input field. To transfer the value directly into the variable of the text field the scan procedure must be terminated with an ENTER (CR).
You enable the ENTER function by scanning the corresponding DMC code in the manual.

 

A detailed description of the devices is available in the relevant manuals in the following entry IDs.

  • SIMATIC MV320/ SIMATIC MV325 (Entry ID 78905254).

Important

  • The above recommendations do not reflect any official endorsement of equipment - except for the Industrial USB Hub 4. They simply represent a recommendation which is based on previous experience. In other words, responsibility for the use of these devices rests with you.
  • The current carrying capacity of the USB port differs depending on the type of operator panel. Refer to the relevant device manual in each case for precise specifications. It might therefore be necessary to provide an extra power supply for the device connected, for example, via the Industrial USB Hub 4.
