Step 1: Connect your PC to your PLC and setup RSLinx to communicate to it. Getting A-B PLC data into Excel using RSLinx With the above in mind, you'll need a version of RSLinx (Classic) other than the free “Lite” version for the following steps to work:

It also included a license for RSLinx OEM so users could test the code they wrote.

RSLinx SDK ($n/a:) This version of RSLinx was for the development community and included documentation and examples of connecting to RSLinx from development environments like Microsoft's VisualStudio.

In the past it was common to have a single PC on both Ethernet (office network) and DH+ ( PLC network) and use RSLinx Gateway as a bridge between the two.

RSLinx Gateway ($2,290:) This version is a Local and Network OPC and DDE server, but also includes the ability to use a PC as a network bridge.

RSLinx Professional ($n/a:) This version was a local OPC and DDE server like OEM, but also included the RSLadder 5 and 500 ActiveX's. This package is no longer available.

RSLinx OEM ($1090:) This version is a local OPC and DDE server for unlimited “devices” ( PLC, PAC,) and also has all the features of the Lite package.

RSLinx Single Node ($541:) This version is a local OPC and DDE server for one “device” (one PLC or PAC,) and also has all the features of the Lite package.

NOTE: This version is not an OPC or DDE server and can not be used to connect to Microsoft Excel.

I have successfully written/copied macros to import all of the dbf files in a given folder to one worksheet, but I only get 65,000 rows of the 138,000 rows in the dbf files.If you would like to display data from your Allen-Bradley PLC or PAC in Microsoft Excel, and have a licensed copy RSLinx Classic (aka RSLinx,) it can be accomplished using a few simple steps we'll cover in this article.īut first, lets identify which copies of RSLinx (aka RSLinx Classic) are licensed by reviewing all the versions below: I would like to have a single row for each time with the values for each of the 24 variable in separate columns.Ĭan this be handled in Excel or is Access the only reasonable approach. So, time zero has 24 rows, time 00:00:15 has 24 rows. But, it was created with a row for each time and each tag number. This would be easy to handle in excel if the dbf files were created with all of the values for a given time in one row. The data is comprised of 4 columns (A = date, B = time, C = tag number, D = value). The file is made up of data that is taken every 15 seconds for 24 different variables (or tag number) and the date and time is recorded. I have dbf files (generated daily) that are about 138,000 rows long (obviously too long to just open up with excel).
