4. LMS244 Configuration 

 

4.1. Tool Bar 
 

Once the parameters of a system have been defined it is necessary to transfer the configuration to the 
LMS244 where it can be stored to be used exactly as it has been programmed. 
 
This is achieved by use of the Menus or the Tool Bar. The functions of the Tool Bar are as follows: 
 
 
       1   2    3   4    5    6    7   8   9   10  11 12                                             13

Depending on whether the software is used in online or offline mode, some icons on the tool Bar will 
remain inactive. 
 
 

Saving Configurations 

A current configuration can be saved at any time to the PC by selecting the icon Save File or by 
selecting the option Save or Save As from the File Menu. LMS244 files have the extension .lms. 
 

Retrieving Configurations 

Previously saved configurations can be loaded into the program by means of the icon Open File or by 
selecting the option Open in the File menu. 
 
To load a configuration from the LMS244, the PC must be connected to the LMS244. If the program 
was started in Offline mode it will be necessary to go Online before file transfer from the LMS244 to 
the PC is possible. This can be achieved by the icon Connect LMS244. 
 
 

Please Note

 that the LMS244 processor must be in the main menu in order to be able to establish 

inter-communication. 
 
Once the connection between PC and LMS244 is established the icons of the toolbar relevant to 
communication will be active. 
 
After selecting the required configuration and loading it to the program, one of the 19 available 
memory positions within the LMS244 can be selected by stepping the User Program number up or 
down until you reach the memory position required.
