The software i am using is STEP7 and the hardware is C7-635 Touch screen and a MM440 drive.Can anyone help me on how to send data to the drive to start and stop it,change the frequency and to change the data sets.Thanks.
I have heard that there is a problem with the C7 devices that they dont really have retentive memory. You may have a problem there.
(Siemens would do us and themselves a favor if they scrapped the lot).
