In case the CPU with the configured IP is not found in the network or the active CPU has a different
IP, a message will appear on the screen during the Login, requesting to the user the possibility of
changing the previous IP by the configured (Yes option) or No and quit sending the project.

Libraries
There are several programming tool resources which are available through libraries. Therefore, these
libraries must be inserted in the project so its utilization becomes possible. The insertion procedure
and more information about available libraries must be found in the MasterTool Programming
Manual – MP399609.
Inserting a Protocol Instance
The Nexto Series CPUs, as described in the General Features chapter, offer protocols as the
MODBUS. The desired protocol instance must be added and configured in the communication
interface as shown in the Protocols Configuration chapter.
Two cases of MODBUS protocol insertion are described below: one in the serial interface and the
other in the Ethernet interface.
