I would start with where the information is stored in the PLC. Can you monitor the location in the PLC and see the information that you want to display? Remember that the HMI is simply a reflection of the information that is currently in the PLC. Regards, Garry

Hi Dave, Can you change the  sick barcode reader  to produce a start character sequence? This way you may be able to eliminate some the information that you need to search for in the PLC. http://www.edata.omron.com.au/eData/PLCs/CP1/W451-E1-03.pdf Look in the above manual for  '3-31 Text String Processing Instructions' This will have several instructions that you can use to search, move or compare. Regards, Garry

Another option to get information out of the PLC is to use another program in the PC to request the data. Here are a couple of options: AdvancedHMI https://sourceforge.net/projects/advancedhmi/ Here is an example of communication using the CP1H: https://accautomation.ca/omron-cp1h-advancedhmi-communication/ Video - https://youtu.be/5_FZ61Ep6u0 VB6 https://accautomation.ca/how-to-implement-the-omron-plc-host-link-protocol/ VBA https://accautomation.ca/how-to-implement-the-omron-host-link-protocol-part-2-vba/ VB.Net https://accautomation.ca/implementing-the-omron-host-link-protocol-vb-net/ CX Server DDE https://accautomation.ca/implementing-the-omron-cx-server-dde-and-excel/ Hope this helps you out.

I would try using the  PLS2(887) with ACC(888) (Independent, target frequency of 0 Hz) instead of the PLS2(887) with INI(880). This will then point to the issue.  https://www.myomron.com/modules/KB/file_d.php?id=544 Regards, Garry

I would use controller link to share information between the controllers. https://industrial.omron.us/en/media/W309-E1-11_ControllerLinkUnits_OperManual_tcm849-112998.pdf Regards, Garry

Take a look at the  ASCII CONVERT: ASC(086) instruction. You could set up a memory area with your standard message. " Row **, Column **, Slot ** " The ** will be filled in using the ASC command with the appropriate information.  Regards, Garry
