Establishing an online connection (Online mode)
Figure 10. Establishing an online connection
In online mode, there is an online connection between the PLC and one or more
devices. An online connection between the PLC and the device is required, for example,
for the following tasks:
• Using the Control Table
• Testing user programs
• Displaying and changing the operating mode of the device
• Displaying module information
• Comparing blocks
• Hardware diagnostics
Before you can establish an online connection, the PLC and the device must be physi -
cally or remotely connected.
After establishing a connection, you can use the Online and Diagnostics view or the
Online tools task card to access the data on the device. The current online status of a
device is indicated by an icon to the right of the device in the Project Tree.
To establish an online connection between the PLC (Profinet Controller) and the device
(Profinet Device) proceed as follows.
• In the Project Tree (see point 4 under "
Project overview" on page 15
) mark the
folder of the PLC that is configured as the Controller.
• Select the Go online command in the Online menu bar to establish an online con -
nection to the PLC (Controller) and to the device (Device).
• If the device has already been connected online, the online connection is auto -
matically established using the previously specified connection path.
• If there was no previous connection, the Go online dialog opens.
• Select the connection path:
- select the type of interface;
- select the interface of the PLC;
- select the interface or the subnet for the connection.
• Click the START SEARCH button. Devices which can be reached by the set connec -
tion path are displayed in the Compatible devices in target subnet. The connection
line in the graphic is displayed as solid.
