Agreed, I just don't have the patience that you have. |

SOFTWARE: TIAP (TIA Portal) Updating the software is a good idea. https://support.industry.siemens.com/cs/document/109311724/ Step7 and WinCC is handled together (even if x2 components of TIAP), but the PLCSIM components needs to be installed on its own. For the simulator you have to have PLCSIM V13 SP1 Update 1. The bad news: Hardware related functions (HSC / PTO / PWM / communications / ++) cannot be simulated. For your purposes for the HSC (high speed counter) the simulator will not help you. But it will be helpful for the general coding. ENCODER HARDWARE It is likely that the encoder you have is "quadrature" type. But is can easily be the type where the A phase gives pulses when turning forward and B phase give pulses when turning reverse. The way the signal is given out also differs. There are differences in NPN and PNP signalled encoders. For the project sake you will have to know what it is. I will assume (because of not having enough info): quadrature PNP connected encoder where only A+ and B+ is connected to the PLC. It is your responsibility to make sure by looking at the specification sheet of the encoder or getting the "client" to tell you. The Z phase is triggered once per rotation. I will not spend time on this aspect. It will not be used now. As a bonus note.. if the actual encoder counts in the opposite direction as you want it - swap the wires A+ and B+. |
