Siemens Plm Download Server

[Su Strawderman]

One of the server modules on my PLC racks suddenly came up with a message stating that the station had stopped, with the server module missing. I can quite plainly see the server module; it's physically present. I've also switched it for another one but that didn't seem to do anything either.

I'm not finding the TIA Portal diagnostics to be very helpful. I've tried restarting the PLC rack a few times, as well as the box holding the IO Controller, and the IO Controller user program, but nothing seems to work.

As it turned out, one of the circuit breakers was tripped at the back. I discovered this when I set every single module on that particular "rack" containing the ET200SP to show all diagnostics, and received more meaningful fault messages.

Im trying to connect my Logo! V8.3 BM to the cloud following this video and this tutorial.
In the 'cloud connection settings' the Thing is successfully registered. But when I test the connection. I get an error saying 'DNS server in not accessible. Check the LOGO! BM gateway to ensure that the logo! BM is connected to the internet'.

I can download the programs to the LOGO! through Ethernet so they should be least on the same subnet. Do I need to configure the router in any way to make the LOGO! connect to the cloud?

Thanks in advance!

When i go to Diagnosics > cloud > test connection on the Logo BM itself I get different errors depending on if the program is running. When the program is running i get the error " Test connection Error 81: Unable to connect to DNS server". and when the program is not running I get the error "Test connection Error e0: Unable to establish TCP connecting to Cloud server"

3. specify the data you want to transfere to AWS in the data table and set date and time in LOGO!.
I believe with central eu1 and Germany/Netherland it should work because there is time different between Berlin and Amasterdam.

While connecting plc to the AWS Cloud, we are getting error...Like " dns server is not accessible. check the logo! BM gateway to ensure that the logo! bm is connected to the internet". How to rectify it?

As far as i know, there are currently two OPC-UA Server dedicated for S7-1500. One is from Siemens and the other is the one from TANI Kevin mentioned above. Both support symbolic access to optimized data blocks.

Starting with the new V14 software version, Siemens offers CPU integrated OPC-UA for a reasonable price (reasonable for Siemens pricing ). Maybe this is an option if you don't want to buy a seperate server.

Everything works except for complex DataTypes (aka structures aka UDTs). Your UDT in the Siemens program will be exposed in the address space as both a collection of nodes that can be read, written or subscribed to individually as well as a single complex DataType accessible in the value attribute of the parent of the collection of nodes in the address space that represent the UDT. Ignition does not support accessing these complex DataType values yet, but we're working on it for the next major release. You can of course still access the individual nodes that represent the UDT members.

In TIA, those are called 'PLC data types' (SPS Datentypen). What Kevin says means that you can access the individual members of a data type, but in the current version you can not link the complete data type to an Ignition UDT with a single OPC-UA address.

the problem is that whenever i try to download program from ES to Servers, it goes on ENTIRE DOWNLOAD selection automatically instead of CHANGES. its not only happen one time, every time. In entire download it powered off one by one of each server which may causes an issue in system, and according to my previous experience and practice, it simply gives a CHANGES selection which has been download without shutting down each server.

From either 8.2 SP1 or 9.0 if you exceed the limits for the changes download you are no longer given the option to ignore the limits and download changes anyway. So if you ever did OS changes downloads before and you were >1xxx / 1000 for any of the items, you were technically violating the recommendation and doing it. Now Siemens has (IMO correctly) taken this option away to improve system stability.

What issues are you observing/experiencing during entire downloads? It is perfectly normal, and in fact one of the whole points of server redundancy to allow one server to go down and support all clients while the other has maintenance (such as downloading).

there is no problem or issue i have facing in entire download, but to avoid download on ENTIRE option, i am looking for any suggestions. Reluctant in entire downloading process because it consume so much time and fear of losing server.

It looks to me something is wrong with the redundant configuration. Maybe you can check the redundancy settings like configured network card, redundant configuration in WinCC Explorer for both servers, Simatic Shell settings.

Whenever I start Simatic Manager, a message windows "server busy" always pop out.
Previously there was no problem at all.

It says:- This action cannot be completed because the other program is busy. Choose "swtich to" to activate the busy program and correct the problem.

To be honest I am also receiving this message. Not at the moment when start Simatic Manager, at the moment when have open FC (or FB) and clicked to open variable table. Immediately I recive this message, click 2 or 3 times in Retry button and this disappear. I searched in Google and found one suggestion to "clean" pop-up message. Look at -ups-Server-Busy-Error-t221548.html . For this message people say: After Infected with a Virus, Spyware, or Trojan..." . In my case, in advance I knew my computer needs fresh windows installation and for this reason I received "server busy". Finally I fixed in this way. I don't know in your case if this "hard way" is possible. And let's hope someone could suggest real way to solve this message without reinstall of Windows...

Hi,
When trying to compile or download a project with an OPC-UA Server Interface the compiling process crashes. I have tried both TIA V18 and V19 without success. I have tried creating new projects as well and whatever project contains the server interface TIA portal crashes.

I lent to a customer a S7-1200 CPU to test its web server side. Following some online guides I built a RESTful API to which the customer can read and write the "hosted" variables. The customer is reading and writing on the json custom web page via https programming (that I know nothing about) and he asked me if I could add the user/password to the web server to test its response time.

I looked around a bit but I found nothing, I know that there are some S7-1500 CPUs that already have an API interface and I think that I'll suggest to use that, but I was still wondering if someone had any experience or opinions about the response time of the two series.

please consider the main and load memory of the S7-1500 CPU is higher than by the S7-1200 CPU. The S7-1500 CPU Includes the simple functionality of S7-1200 and meets special demands for performance, flexibility and networkability.

I've written a python script that communicates with my et200SP Webserver and i get an average response time of 0.5s per api call. It also doesn't matter how much (i tested from 1 to 10000 integers) data tags i request, it's always the same response time.

Too slow means that for the operation it needs to do it takes too much time compared to what normally a response time is. My customer and I saw that for a full request-cycle it takes 8 to 10 seconds to operate 5 requests.

I don't know if there's an API on the et200sp, but surely there isn't on a S7-1200 and I' not programming in python but in php, I already know that it doesen't matter if it's a bit or a string that the program is requesting.

I'm not sure how fimiliar you are with programming and API's but the 1500-series have an RPC API so you can make a url call from any programming language and you will get a response. doesn't matter if it's python, C#, PHP, JS,....

I tought you've built a RESTFul API on a seperate server and have that server communicate with the PLC over TCPIP or PUT/GET or something but i'm starting to think you've just made something that uses AWP commands, is that correct? This is indeed a very slow method and is not the way to go. Could you clearify your setup?

On another point: i don't think there is anything wrong with asking somebody what they mean with "to slow". If you want good help you need to be detailed and specific. By being rude you don't get anywhere...
