For example, the S7-1500 devices are built on the S7-1200. There is a very good reason to begin with PLC programming from Siemens: Siemens PLC’s are one of the most used PLC systems in factories and machines. The kit is made for beginners and for learning. The cheapest way to start learning PLC programming with Siemens is to get a Starter Kit.

Here are the reasons you should go for the S7-1200 Starter Kit: Especially if you just started to learn PLC programming. Some of the reasons are obvious, but some might not be so obvious to you now. There are several good reasons for you to start your PLC programming career with the S7-1200 Starter Kit from Siemens. You can even control the S7-1200 PLC with your smartphone!
SIEMENS SIMATIC S7 1200 LLPD SOFTWARE
Get the Starter Kit with the programming software SIMATIC S7 TIA Portal and begin learning Siemens PLC programming. It is the latest Siemens PLC and the best for learning. I guess.You probably have heard about the Siemens S7-1200 PLC. Chapter: 6.3.5.31 The "Switch LLDP" WBM menu Industrial Ethernet Switches SCALANCE X-200 / XF-200 Operating Instructions
SIEMENS SIMATIC S7 1200 LLPD MAC
To 3: About your MAC I guess you have a lot of a little bit older SCALANCE X200 IRTSwitches, don't you? Check this manual: each Port, even the port directed to the node itself. So, if each SIMATIC node with an ERTEC 200 or ERTEC 400 Controller has 3 or 5 MAC address. If you want you can disable the LLDP function.

well, if you want to use PROFINET IO IRT and you want it as best as possible you need to know the exact structure and the exact cable length between the nodes. You may ask what do you need this information for. To 1: To identify in detail which device is connected where exactly. Please let me also answer your questions: To find out how I S Systems can help you with your automation needs please visit The advice and opinion given in this thread is that of the author and does not necessarily reflect the views of I S Systems Pty Limited. How do you disable the "Link Layer Discovery Protocol" function at the ports of an IE CP of S7-300 or S7-400?Īs for your third question ( "a LOT of devices are using ALL the same mac address"), I can only speculateif the person who configured your PLC's did this (you can assign/change theMAC addresses for certain Siemens devices). If this "feature" gives you grief, you can disable it and you can find our more about a the link below: CP, Switch) has the "base"MAC address and each physical interface of ithas an individual MAC address (automatically "+1" assigned from thedevices "base"MAC address). This is a "feature" that is used for topology discovery in PROFINET IO systems where the device (e.g. Not being a CCIE myself,I won't attempt to argue with the " OUT OF STANDARDS" point that you make, but can tell you though that your observations about the "multiple" MAC addresses may very well be correct. The switch is going nuts as he is seeing the same mac address on different ports. However, a LOT of devices are using ALL the same mac address for LLDP: precisely: 0800.069d.3840. The Siemens implementation is therefore OUT OF STANDARDS !ģ) We have seen that some of our machines are indeed using the port+1 mac address. I have several questions about this:ġ) Why is Siemens using a DIFFERENT MAC specifically for LLDP ? Why is it not just using the same MAC adress as the interface, which is ALSO unique ? I have not seen ANY single vendor that is using a "new" mac address for LLDP ? This is also disadvantage for Siemens as you will require double the amount of official siemens mac addresses.Ģ) The 802.1AB standard specifically says: "The source address shall be the MAC address of the sending station or port." (section 8.1). This LLDP protocol of Siemens is breaking communications. This means: one port, one mac address max.
