Hi there, I'm not so similiar with PLC , but what I remember was you need to have + on the L side and - on the M.    have PLC300 siemens with AI 8 x 13 BIT (331-1KF02-0ab0) and A0 2 x 12 BIT (332-5HB01-0AB0) and DI 32 X DC24V 321-1BL00-0AA0 and DO 16 x DC24V/0,5A 322-1BH01-0AA0.   Do I need to have any supply to the models to DI and D0? what I mean is, its says L+ on the top and M- on the bottom inside, do I need to do anything with that?

Hi there :D My son's birtday is coming up, and he loves to play with siemens plc 300 so I planted to surprise him at by making a inverter (Altivar 31) connect to PLC 300 and make PLC 300 connect with HMI (Inverter-PLC-HMI) the point is that I want to control the inverter with HMI (the motor speed hz) but I need to program the PLC, which I have no idea how to do. I can configure it, but after that I got no idea.   Can someone please help me or show me, I really want to make this happened.
