Forum,

I have two S7_1214C plcs in different machines which need an IP Address change.  These machines run on a 24hr basis.   I don't have copies of the programs and don't know what Step7 version programmed them   but I got use of  Tia V13.    I can connect to both using "assessable Devices" and show the device with its existing Ip Address.  I have tried to upload the hardware and software from both machines  as a backup but received the following message on one machine.

"the selected object PLC_1(192.168.10.101) cannot be uploaded from device".  This PLC has V4.11 firmware.   IF the program is password protected will this be the message that one gets?.  Maybe  this been programmed with an older version of Tia.

The second PLC upload attempt gave me an incompatible issue.  This PLC is V3.0.  On reading different forums I will have to read this with Tia V11 or upgrade the firmware to work with V13 and then experience the same problem as the first machine.

I bought a test S7-1214C Plc and have familiarized myself with changing the IP Address but I find that it wants to download the hardware change and the software program at the same time.  

As the machines are in a 24hr production environment I want to have a copy of the plc program uploaded just in case the ip address change goes wrong and I can revert everything back.   How does one proceed.?

On reading different problems on the tia Portal forums it seems that one requires all versions of Step7 from Step7 V5.3 thru TIA basic V10.5 to V13 installed to be able to maintain Siemens PLCs in  any capacity.   Backward compatibility is a must for programming software even if its just used for Software backup from machines.

Thanks

Hello,

you don't specify if you have also Service Pack 1 installed on TIAv13, because this can be problem. Also some updates are needed for better functionality. Pls give this important info about SP.

Update: look, probably you can upload Station to PC with only SW version with that PLC was configured/programmed.

Can you describe the steps you executed to get that error message.

Specifically, which menu item did you use to upload the program? OR did you drag and drop?

Screen shots would also be helpful.

I have V13 with update  6 running on Win10.  V13 is running on Win10 happily but I see its not supported yet on Win10.   I'm downloading V13 SP1 and will rebuild laptop with Win7 and reload V13 SP1 on today.  Hopefully this will cure the problem with s7-1214C firmware 4.1.1. and allow me to upload the device ( hardware and software) and then allow me to change the IP Address

Am I right with 1214C with firmware V3.0.   This is not supported by V13 can only be uploaded with V11?

The Company is 1.5hrs away so I need to be armed with proper tools to apply my changes without constantly meeting niggly problems which is stopping my progress.

This is only a relatively new range of PLCs and the most recent software doesn't support the early models of them! 

I've downloaded V13 SP1.  Its 6.6Gb.  This is cumbersome software.  Siemens seem to be going backwards in terms of their software.

I will take screenshots in future when I'm stuck.  No doubt this helps immensely.

Thanks   Fin

I've been asked to change the IP addresses on two labelling machines with S7-1200s to get access to errors on machines for efficiency monitoring.   I have used Step7 V5.3 on S7-300s and  bought Tia V13 last year so I could program the new S7-1200 range as well as upgrading my software for the S7-300s.

I don't have the machine programs or what was used to program them  so I thought V13 would carry out the job as required.   I trialled on a test s7-1214C V4.0 at home and found that I could easily change the address but Tia also downloaded the program to the PLC in the process.

I connected to the first machine and could connect to the S7-1214C.  It showed the IP address and found that it was firmware V4.1.1.  I created a new project in Tia and tried to upload the hardware and software settings to the PC but it told me I wasn't allowed.   Replies on my post tell me I need SP1 to access over firmware V4.0 but before proceeding 

I connected to second machine and could connect to its S7-1214C.  This plc is is V3.0.  Again I set up a project and tried to upload Hw and Sw but again it refused and told me plc wasn't compatible.  I believe I need Tia V11 with all updates to access this Plc.

Am I correct in saying that to change the IP Address that I must go through the motions of downloading the Hw AND Sw at the same time.   Can I not just download the hardware changes ie IP Address on its own without having to worry about the program running on the Plc.

I'm using  Tia V13 update 6 on Win10.  I'm able to connect using "accessible devices" under Online tab.  It shows the S7-1214C plc with its IP Address.

At the moment I'm rebuilding laptop to Win7 and installing Tia V13 SP1 and also getting a download of Tia V11 so I can operate on both PLCs.

Any advice would be very welcome

I don't have V13 and I don't have 1214C V4 so I can not speak specifically to either one but some common sense tells me that if you were able to connect to a 1214C V4 at home then you're good with Windows 10.

A few of things to point out here:

1- Seeing the CPU on "Accessible devices" does *not* mean you are connected. For example I create new project, add unspecified hardware, detect the hardware all of which means that the software can see the device and still not be able to download or upload because of I'm still not connected in a way. The reasons for connection problems are endless.

If you go in the project tree and double click on device configuration and then click go online, if you are able to connect you will get a green check mark on the CPU. See attached snap shot. The one on the right is connected and the one on left is not though it is listed in the accessible devices.

2- Separate your uploads, upload the program first and then try to upload the hardware configuration and note down which one gives you the error.

3- Leave changing the IP address till you resolved your connection problems because you have to be connected to be able to change the IP address any way and uploading the program means you are able to connect.

I realize your access to the CPUs is limited by geography so it is best to spend lots of time getting to know the software at home with your 1214C and recreate, if you can, connection problems to get to know the software better. Even read in this forum other people's connection problems.

Practice taking snap shots of everything you encounter so that when you're onsite you do the same. It helps immensely to see visual clues. William_B posted this link of a "screen capture utility" that I found quite useful. Give it a try.

Best of luck

A couple of points I should add.

- Take the advice of updating to SP1 and any other updates for that matter.

- You do not need to download the software to change the IP but to my knowledge and what I usually do is download the hardware with the new IP to make the change. But that puts the CPU in stop for a moment and if the CPU is live you will have a serious problem.  You also should not be downloading new hardware configuration without knowing with absolute certainty the existing hardware configuration. For example if it had HSC (high speed counters) enabled and you download new hardware configuration without them enables the program is not going to work. Again if this is in your home or lab that's manageable though time wasteful but on a live site I would tread very carefully and make sure I upload the program, the hardware and spend hours getting to know the how everything is setup in my office or home then go back with much more confidence to change the IP address.

Also you did not mention any communication setup between them so I'm assuming they're independent.

Hello Finian,

pls carefully readed my post? I've said that if you want upload some PLC, you need SW that was used for configuring/programing that PLC. If your PLC was programmed in TIAv11, you need TIAv11, it's not important what type of CPU is used. This can be realy hard.
