• Another projected device is using the communication path selected. Example:
• The physical device is already using another communication path:
• The »Engineer« displays the serial number and the name of the project device:
The real device with the serial number <xyz> has already been connected to <name of the
project device>.
• A connection to the project device can be established by confirming the query with Yes.
6.2.2.2
Communication path is currently being used by another device
The »Engineer« issues a warning if several devices within the same project attempt to access the
same communication path. This prevents several devices from being online via the same
communication path. Example:
• Further use of the communication path is not possible. Activating the OK button closes the
dialog box. Select another configuration for the communication path of the other device.
Setting the communication path
Several project devices access the
same physical device
Function
• By means of the serial number the »Engineer« detects that several project
devices attempt to access the same physical device via different device
access paths.
• If one of the other project devices is online, the communication path will
be occupied. The second device attempting to use the communication
path will be set offline immediately.
Remedy:
The communication path must be set.
• The reading out of the serial number must be switched off manually.
