We have a pc program where we can choose if we want to turn around the horizontal axis('H') or around the vertical axis('V'),throughout the ppi cable is it send to the plc. With this application we can only go further, if we want to go backwards(for example with a 'K') is it enough to change smb2=='k' and switch the sequence of Q0.5 and Q0.7(attachement),those are the outputs responsible for driving the motor???

Thanks juan
