I am currently working on configuring a label printing system using a CompactLogix PLC and a Printronix printer. The label design includes a barcode, part numbers, date & time stamp, and our company name. However, due to a recent change in our company name, I need to update the label formatting accordingly. In the past, I have successfully made similar modifications on CompactLogix PLCs by editing the "printStrings" function. However, in this particular program, it appears to be structured differently, possibly utilizing user-defined data types. This has left me unsure of where to begin with making the necessary changes.
Here are a few suggestions for troubleshooting PLC communication with a printer over EIP: 1. Make sure to read the manual (RTFM) for guidance on troubleshooting. 2. Check the data area associated with the printer and monitor tags to locate where label information is sent. Cross-reference this with the code for further insight. 3. Search for any specific routines related to the printer or labeling process. 4. Some printers have a configuration file that dictates label layout and contains both hard-coded information and variables written by the PLC. Ensure that the PLC does not overwrite critical information in the printer's configuration file. If unfamiliar with Printronix printers, research for similarities in their setup.
It sounds like you've got a bit of a complex configuration issue on your hands, but fear not! With CompactLogix PLCs, applying changes to user-defined data types typically involves adjusting configurations in the Controller Tags. Try looking for the specific tag that controls the company name on the label. Once found, you can adjust it with the new company name. If the user-defined data types are nested or complex, you might need a bit of careful navigation, so it's crucial not to rush it. Make sure you document your steps as you progress, it could be a lifesaver for future modifications. Good luck!
It seems you might be dealing with a slightly more complex configuration if user-defined data types are at play here. Have you looked into the possibility that the label’s text might be located within the Logic Designer under "tags"? If the former programmers utilized user-defined structure, they might have placed the company name in a string variable within a specific structure. You may want to check those areas and see if there's anything that resembles the current company name. If you find it, simply update the information accordingly. If it's not there, don't hesitate to provide more details and we can potentially pinpoint the right approach together.
