At the same time, even if it did know the IP address, it would not know what slot the processor is in.   We need to build the path.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">RSLinx Configuration<\/h4>\n\n\n\n<p>If you have not already done so, you need to set up a communication driver in RSLinx.  When connecting over Ethernet, use the <a href=\"https:\/\/bryceautomation.com\/index.php\/2017\/05\/26\/rslinx-ethernet-driver\/\">Ethernet Devices <\/a>driver, or the Ethernet\/IP driver.  If you have an older processor, such as the L6x, L55, or L1, you might be using a null modem cable to connect to the serial port.  In that case, you would consider using the <a href=\"https:\/\/bryceautomation.com\/index.php\/2017\/05\/26\/rslinx-df1-driver\/\">DF1 driver.<\/a>  On the other hand, if you have newer modules, you can connect with USB.  Simply open the RSWho screen in RSLinx.   When you plug in your USB cable, you should see the USB Devices driver appear automatically.<\/p>\n\n\n\n<p>In this case, I have an Emulator.   I will choose the virtual backplane driver.   Once you go to the RSWHO screen (under Communication | RSWHO), you should be able to click on the driver.   Depending on how you are accessing the processor, you may need to click the + on the driver, and communication module to go across the backplane to see the processor.   It&#8217;s important to realize, it&#8217;s the PROCESSOR that we are looking for to verify communication.  In this case, I have a program in the processor called &#8220;MCR&#8221;, and the processor is in slot 2.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"512\" height=\"276\" data-src=\"https:\/\/bryceautomation.com\/wp-content\/uploads\/2021\/02\/image-20.png\" alt=\"\" class=\"wp-image-6056 lazyload\" data-srcset=\"https:\/\/bryceautomation.com\/wp-content\/uploads\/2021\/02\/image-20.png 512w, https:\/\/bryceautomation.com\/wp-content\/uploads\/2021\/02\/image-20-300x162.png 300w\" data-sizes=\"(max-width: 512px) 100vw, 512px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 512px; --smush-placeholder-aspect-ratio: 512\/276;\" \/><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Resolve ControlLogix Communication Path Needed<\/h4>\n\n\n\n<p>Now that we are sure we have communication, go back to RSLogix \/ Studio 500.

If you do not have an ACD file for the processor, simply create a new file.
