Connecting Your PC to the ControlLogix Processor There are several ways to establish communication between your PC and the ControlLogix processor. The following steps show how to establish communication through the serial interface. It is not mandatory that you use the processor's serial interface. You may access the processor through whatever network interface is available on your system. Refer to your Rockwell Automation documentation for information on other connection methods. 1 Connect the right-angle connector end of the cable to your controller at the communications port.2 Connect the straight connector end of the cable to the serial port on your computer.

Opening the Sample Ladder Logic

 The sample program for your MVI56-EGD 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.

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.5 In the Connected To Go Online dialog box, click the GENERAL tab. This tab shows information about the processor, including the Revision (firmware) version. In the following illustration, the firmware version is 17.2.
