Bonjour à tous,

Je fais appel à votre aide, j'ai un automate S7-300 sur un site de production sans carte mémoire, mon responsable me demande d'insérer une carte et sauvegarder le programme.

J'ai trouvé des cartes dans mon stock mais j'ai peur de l'inserer et mettre l'automate en panne car je ne suis pas sur du contenu de ces cartes.

On m'a conseillé de mettre l'automate en mode stop, insérer la carte, la formater puis transférer le progamme de l'automate vers la carte mémoire.

PS: J'utilise Tia Portal V15

Avez-vous d'autres conseils svp?

Hello everyone,

I'm asking for your help. I have an S7-300 PLC on a production site without a memory card, and my manager is asking me to insert a card and save the program.

I've found some cards in my stock but I'm afraid of inserting them and causing the PLC to break down, as I'm not sure what they contain.

I was advised to put the PLC in stop mode, insert the card, format it and then transfer the program from the PLC to the memory card.

PS: I use Tia Portal V15

Do you have any other advice?

Hello,

without doubts, S7-300 can work without memory card, question is what exactly order number and firmware of S7-300 CPU. If I could say, yes, confusion is here, especially with use of TIA and mentioned CPU type, old probably because in case of new type of CPUs they doesn't work without MMC and his description then is really strange. I see this situation like old S7-300 CPU (or maybe other HW component on some comm network) what isn't maybe compatible with TIA portal, especially old S7-300 CPUs are that are not compatible for sure. In this case only Simatic Manager can be used with cfg. User need describe his situation more preciselly.

Hello,

without doubts, S7-300 can work without memory card.

 Which one?

Hello,

every model which doesn't use MMC. It is easy to check inside Step7 Manager or on spare part shops and also still on many existing places where are still functional

One example from that big family (old models): 6ES7 315-1AF03-0AB0 (v1.2) I have also at my place

I see simply problem with user's description of problem, he simply haven't described his situation correctly and precisely, especially about that HW type and SW used.

Gustavo, read pls carefully again his description of problem:

Easy to understand what is matter looks like. If it is as you say, then it is not possible to have that CPU in production, true? But he has it, but only with TIAv15

Let him describe his situation better and preciselly so we are not confused with his not good description. Maybe he will tell us that he has only new CPU (not old but new model supported with TIA) but only without MMC card, simple situation but this he didn't tell us correctly

Hello,

no problem, look at this as example where MC card are supported (not MMC):

simply in this old model MC isn't required generally but battery need to be inserted of course to have all there inside also after power off/on. In case you will do with key switch hard reset and you haven't MC card inserted inside with program downloaded to it, you lost program and you have clear PLC. So I've understood his situation like this (he said that he has in factory site some CPU) so he has working CPU and they decided to prevent this CPU to be clear after reset as example, so they want better insert MC card and save prj inside to have all ok also after reset, in case. You can now see how it is important to describe situation correctly and with more clear informations, simply to not be confused. Also is clear here that this CPU isn't supported with TIA portal (all versions).
