It seems I can't make changes online because I'm changing adapter parameters. I have to write the changes with PLC stop. Thanks for the advice. -
Yes I agree with Sergey one other point, if this is one of those clones it could be that the OP has selected to download the PLC Parameters this also will not work as most of these clones you cannot change the PLC Parameters, found this out when called to do a mod on a machine using a clone FX. -

And also send a picture of second Tab "Device" those could be out of range as well. -

1) The processor is a 551 Series B FRN 4 2) The serial port is free, but We want to use the ethernet port with a switch (actually the port is used by a RSView32 Application and Windows 2000) We will probably replace RSView32 with FactoryTalkView 11 in a newer PC. FTV could create this excel file? Thanks in advance. -
Deleting memory is not quite what I meant, I suggest you create a new empty file, go online to the plc and upload the plc parameters and compare those with your program what model of plc is it as this matters Can you post a zip file of your code. Check the actual plc parameters and the memory capacity as shown below Eliminar memoria no es exactamente lo que quise decir, le sugiero que cree un nuevo archivo vacío, acceda al plc en línea, cargue los parámetros del plc y los compare con su programa. ¿Qué modelo de plc es? Esto importa. ¿Puedes publicar un archivo zip de tu código? Verifique los parámetros reales del plc y la capacidad de la memoria como se muestra a continuación

You can download different firmware versions for different PLC's from SiePortal (Siemens automation portal). -

Elimine la memoria del PLC y aun me aparece lo mismo Translation: I erased the PLC memory and I still see the same thing -

Intento escribir otro programa que tenia el PLC, y me sigue apareciendo lo mismo ¿será problema de memoria? ya elimine la memoria del plc Translation: I'm trying to write another program that the PLC had, and I keep getting the same thing. Could it be a memory problem? I've already cleared the PLC's memory. -

As part of my research, I am attempting to perform a comparative analysis of firmware structures across different generations of Siemens PLCs (S7-300, S7-400, S7-1200, and S7-1500). However, I have encountered significant difficulties in locating valid firmware images for these specific models to analyze in a research setting. Would it be possible for you to share any anonymized or older firmware samples for these series that you used in your research? -
I don't have an answer for you but many here will, I'm sure. They will however ask: 1) What is the Firmware revision of the SLC 5/05? This will make a difference in the available protocols on the Ethernet port. 2) Which ports are available on the SLC 5/05? Or which do you plan to use? -
There are a lot of gateways (or protocol converters) out there but I've never used them for this particular purpose. For the money, you'll be better off getting a CJ1W-ETNxx module and use FINS protocol. What HMI are you using? Most manufacturers support FINS for Ethernet and Host Link for Serial.

Cloudflare seems to be the one to go for, however, a week or so ago cloudflare had a problem for over a day, no details so no idea if it was down for maintenance or it'self had been subject to an attack, it now uses AI. funny really, AI to block AI lol. I know in the past it has caused problems where due to some problem or settings cloudflare was stopping acess to sites for some people but that seems pretty rare now. There is a basic free version that has CDN & DDos plus some others, how long it will be free is anybodys guess
