Why does it say that connectors must be GOLD? What does this means? I looked at Appendix C, and there is no information on what this means or what it's referring to. |

Hello, I am wonder if you guys can help me with the following: I have a problem with Going online with my Siemens S7-1200 PLC… When I connect directly hard wired to this PLC, I can successfully connect to it. In this direct connection, when I go to "Accessible devices", I see 3 options via PN/IE: 1) Dual Band Wireless-AC 8260 and the only method that works for me is when I select "Ethernet Connection (2) I219-LM", and when I press the "Start Search" my PLC populates. This PLC has the IP address 172.19.48.125. The subnet mask and Gateway/Route address corresponding to our network protocol in our plant. However, when I go and connect this PLC to a network-switch which is connected to a network drop coming from our Server room. (On this network-switch I have other Allen Bradley PLCs too). When I ping the Siemens PLC new address, I get a reply....(and the software TIA portal v13 is an allowed program on the firewall) The issue is when I try to connect TO this PLC from my Wireless card on my laptop. This time, I can only select two options via PN/IE 1) Dual Band Wireless-AC 8260 I proceed to select my Wireless Adapter from my laptop ("Dual Band Wireless-AC 8260"), but when I press the "Start Search" button, and nothing comes up. Is there a different procedure in connecting to this PLC via WiFi? (Via Wifi, I am able to access Allen Bradley, and Omron PLCs this way and going online with it, but not Siemens). Any recommendations on what to do on this case? I would very much appreciate your help. Thank you. |

Siemens means this (take a look at attachment). AttachmentS7-1200 manual pages 1565+1566.pdf (194 Downloads) |

The problem maybe because you hadn't defined the Router in your PLC IP configuration. Without that configuration, you maynot be able to find your PLC in a different subnet. If your WIFI Router is in the same subnet as the PLC, then you don't have to set this router function. First ensure your WIFI router IP and your PLC IP and then let us know. Thanks, Jay

Thank you for your response. I have actually defined the Router Address in my PLC and this is the reason why I am able to ping the PLC IP address and get a reply (via WiFi from my Laptop). It is just that when I proceed to select my Wireless Adapter from my laptop ("Dual Band Wireless-AC 8260"), and then I press the "Start Search" button, and nothing comes up. |

Did you also checked the PG/PC interface in your control panel whether it is pointing to your wireless adapter or still with Ethernet? Thanks, Jay

The "start search" button uses a non-routable protocol. You need to VPN into that network to use the start search button.

Hello guys, Thank you for your response. My issue is now resolved. It turns out that I had to go “Extended go online” and manually type the IP address. I still don’t know why it doesn’t show on the “Accessible devices”. Someone told me that the culprit could be the Version of the TIA-Portal (v13) I am using; and that I need to use a more updated version. They said that TIA-Portal (v13) has caused problems in the past for going online Again, thank you for your response. Have a great day! |

Hello, because between the PLC and your Wifi adapter is a Router an the Search works with MAC Broadcast which can't be routed, so the PLC can't be found ! Regards Christoph |

If that is the case, then Siemens needs to make that improvement. Their competitors have it worked it out as friendly usage and simple connection. |

Hello, this is not a issue of Siemens! This is a basical princip of network technologies! contact you IT and they should open all broadcast restrictions on all used networkcomponents in the network. Regards Christoph |

Yes what you said is right. It is not the problem with the SIEMENS stuff. Because I am able to search and also connect my PLC and HMI seamlessly through WIFI. Jay
