Dear John, The hardware configuration and Netpro are in the "suitcase" thatare in the block container. The program and datablocks are copyed from the load- to the work-memory when the CPU is starting. "Then it would be true that if I wanted that data, I would have to connect with my PG and in S7 use the load RAM to ROM, then the current data block infor is moved on to the MMC.", that is not necessarry, the datablocks have different stati, see the link S7-300 Memory Cards -- Product information -- Technical data, so you are not realy synking When you power down the CPU and replace the MMC, thenit is not necessarry to do some tricks to get it working, when you are waiting long enough, then there is nothing any more in the work memory and the CPU doesn't know what he have done before... |
I hope that the answer will help, if you have still questions, don't hesitate to ask me. |
