I have been working with a s7 400 plc. I added a couple networks and the on downloads I get a message that there is not anough memory to load.I cant beleave this because I only added a move statement and a m bit. Is there a setting that could be wrong in the maneger that would cause this or any other Ideas?

Try compressing the memory.

yes, no problem.

another thing, it downloads the whole block not just the changed networks, so if the block is quite big and you have not much memory left then you will get the memory full message.

When you go to the compress memory page, it will show you graphically how much memory you have and how much used.

Don't forget, the memory used may have built up, when was the PLC last compressed or downloaded?
Small changes over months, maybe years, could have accumulated, so it may not only be your modification.

oh.. and if your unlucky, it will be too full to compress, I've had that in the past.
