" Modular machines or tool changers require network segments or individual nodes to be connected and disconnected during operation. EtherCAT slave controllers already include the basis for this Hot Connect feature. If a neighboring station is removed, then the port is automatically closed so the rest of the network can continue to operate without interference. Very short detection times <15µs guarantee a smooth changeover" https://www.ethercat.org/pdf/english/ETG_Brochure_EN.pdf The above may help you out. Regards, Garry

What you want to do is to look at the PLC’s that are being used in your area. What manufacturer is the most common? What are the models that they are using? What programming language is being used? This will help to ensure that the PLC that you install, is supported both by the manufacturer and support personnel throughout its life.  Just some thoughts. Regards, Garry

Yes, the good old days. What about the cassette tape backups! Omron FIT (Factory Intelligent Terminal) was the portable programming device. Google Pictures of the Omron FIT10 You must be at this awhile to gtsuport!  

Yes, I remember programming them before the K series arrived.  Great PLC for the time. Garry

Wow Jay  You put a lot of work into this controller! Regards, Garry

Here is a free series on the Omron CP1H PLC. This will cover all of the basics. https://accautomation.ca/series/omron-plc-cp1h-series/ Here is a beginners guide to PLC programming that you might find helpful: https://accautomation.ca/programming/plc-beginners-guide/ Regards, Garry

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      

Has the cable you used connected before? Has the computer communicated to this device before? If not then check the serial cable? http://www.plctalk.net/qanda/showthread.php?t=28573 http://www.plctalk.net/qanda/showthread.php?t=25511 The above threads may help you out. Regards, Garry

I am unaware of any way to do this. https://control.com/thread/991324342 http://www.plctalk.net/qanda/showthread.php?t=14080   Regards, Garry

http://www.plctalk.net/qanda/showthread.php?t=118411 Suggest to contact manufacturer for the answers. 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.

Have you checked the program documentation. It may contain the information that you need.  http://www.plctalk.net/qanda/showthread.php?t=85122 http://www.plctalk.net/qanda/showthread.php?t=2329 Regards, Garry  

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

https://accautomation.ca/creating-a-flip-flop-circuit-in-the-plc/ I'm not certain on what you require, but it sounds like a flip flop circuit. Hit the button once and the output will turn on. Hit the same button again and the output turns off. The above link will show you the plc logic.  Regards, Garry
