#26 - Rockwell PLC importing and exporting Rungs and Routines

In this post we will show you how to import and export Rungs and a Routine in a program on RSLogix5000. This method can help, for example, during a software update sent by colleagues or remote vendors. The same principle can also be applied to the Import / Export of Data-Types, for example a UDT, Add-On Instructions and even Tags and comments (in Tools> Import).

First we will configure the simulator in RSLogix5000:

After inserting the modules and configuring IO mapping and the RPI, which is increased from 5ms to 50ms, we tested the simulator inputs and outputs to verify that the connection between the CPU and  IO card is working:

We created a simple logic as a test that we will export and import on another CPU. In this example, we wrote the commands and IO addresses in Excel and Word to replace paragraphs and large spaces (^ p and w) with single spaces.

sor xic Local:8:I.Data[1].0 ote Local:8:O.Data[0].0
...

We created a Subroutine called IO_Mapping and inserted the text above. This operation is done with the PLC online, in order to simulate a software edition when the factory is in production and the PLC is online.

Right-click on the Rung and export. A document with the extension .L5X will be created, which is an XML format. Also export to Routine following the same steps.

On the other CPU, right-click on the Rung and Import.

When doing a check of the Program it alerts you that an error, because the Routine that is being called does not exist yet:

Importing the IO_Mapping Routine, we can see that when it was exported, the IO chart was at 8.

Therefore, we have to correct the address because on that CPU the IO card is in slot 6.

Once imported, the PLC is online and awaits confirmation, which we do after checking the logic and IO addresses by clicking on the Verify Routine button:
