Just been e-mailed a S7 program to look at for some one but have recived two files. One is a .Pdb which i'm assuming is a protool file but the other was a .mwp which I never heard of.
It is a program file for Siemens S7-200 PLC. To configure or open a S7-200 program you need Step 7 MicroWIn software.. .mwp stands for microwin project..
