In case the Ethernet configuration of the CPU to be connected is in a different network from the Ethernet interface of the
station, the software MasterTool IEC XE will not be able to find the device. In this case, it’s recommended to use the command
Easy Connection located on Online menu.
Figure 25: Easy Connection
This command performs a MAC level communication with the device, allowing to permanently change the configuration
of the CPU’s Ethernet interface, independently of the IP configuration of the station and from the one previously configured on
the device. So, with this command, it’s possible to change the device configuration to put it on the same network of the Ethernet
interface of the station where MasterTool IEC XE is running, allowing to find and select the device for the communication. The
complete description of Easy Connection command can be found on User Manual of MasterTool IEC XE code MU299609.
