1.7  Using the Sample Ladder Logic 
The sample program for your MVI56-HART module includes custom tags, data types, 
and ladder logic for data I/O and status monitoring. For most applications, you can run 
the sample ladder program without modification, or, for advanced applications, you can 
incorporate the sample program into your existing application. 
The inRAx Solutions CD provides one or more versions of the sample ladder logic. The 
version number appended to the file name corresponds with the firmware version number 
of your ControlLogix processor. The firmware version and sample program version must 
match. 
1.7.1  Determining the Firmware Version of Your Processor 
Important: The RSLinx service must be installed and running on your computer 
in order for RSLogix to communicate with the processor. Refer to your RSLinx 
and RSLogix documentation for help configuring and troubleshooting these 
applications. 
1  Connect an RS-232 serial cable from the COM (serial) port on your PC to the 
communication port on the front of the processor. 
2  Start RSLogix 5000 and close any existing project that may be loaded. 
3  Open the COMMUNICATIONS menu and choose GO ONLINE. RSLogix will establish 
communication with the processor. This may take a few moments. 
4  When RSLogix has established communication with the processor, the Connected To 
Go Online dialog box will open.
