Only possible if the original programmer enabled that option. -
I want to ask one more question in this topic. How can I back up the project from the controller? I don’t want to upload it with editing purposes, I need to have it, if something happened to the hardware. Is it possible to use SD card or other way to get in (in compile form for example)? I need to have in case of controller problem and be able to load it in new PLC. -
I've made a routine - a for each loop - with a list of tags including buffer tags and real tags. I want to copy one tag (real) into a data table with the instruction Set DTI column value B = real value C= real value of the structure current item after compiling I get a lot of errors.... as you can see, 118 error's........ But I found a solution -> store the real tag of my structure into a local real tag and then put this tag as value to store (C), then I have no error's..... Good to know, so I wanted to share this with thee community (or maybe this is a bug?) -
Also, don't get confused between your wired ethernet address and your wireless address on your PC. When you do IPConfig in a command window, confirm which address is which since they are usually on different subnets. You want to make sure you use your wired IP address subnet. -
That is your Subnet MASK, not your subnet. Your subnet is 192.168.0. You need to make the subnet match between the PC and PLC (the first 3 octets must be the same and the 4th octet different). The subnet of the PLC, as you show above is 10.2.5. Also, are you certain that 10.2.5.83 is the IP address of the PLC? Even so, go into UniApps and change it to 192.168.0.xxx (anything other than 71). Or, you can go into your PC network settings and change your PC IP address to 10.2.5.xxx (anything other than 83). Once you do that you should be able to communicate if you are plugged into the correct port with a crossover cable or through an ethernet hub.
