Dear experts: Please I need help with the S7-1500 PLC Simulation, I am simulating an elementary program that reads a digital input and writes it to a digital output, but forcing the digital input does not activate the output, try with a Observation table to force the input and it doesn't work for me either, the only way it works is by replacing the digital input with a memory (M0.0), I tried other S7-1500 CPUs and it didn't work for me. This same program does work with S7-1200 PLC. Installed Software: TIA Portal Step 7 Professional V13 SP1 Update 4 S7 - PLCSIM V13 Windows 7 Enterprise SP1 64-bit Thank you very much for the help you can give me. ------------------------------------------------------------------------------------------ |

Hola José; Bienvenido al foro de Siemens. En su primera carta, Ud. nos escribió en ingles, pues pasó al español para discutir con Rambo, pues el tambien habla castellano. Pero estamos aqui parte de una communidad de miembros que vienen de muchos paises, muchps no hablan español, y hemos escogido el ingles como idioma de intercambio en el foro para facilitar el entendimiento entre todos. Le ruego ue nos escriba en ingles a su pr-oxima visita. Hello José: Welcome to the Siemens forum. In your first post you wrote to us in English, the switched to Spanish to discuss things with Rambo, who also speaks Spanish. That leaves out many members of opur communityu, who come from many countries where Spanish is not spoken. We have chosebn English as an interchange language to make exchanges easier on the forum, and more can participate. Please write to us in English on your next visit. Did you try to modify(with a watch table) or actually force (with a force table) the value of your digital inputs? Maybe the following video from YouTube can explain (in English) the difference between the two, and how to use them: https://www.youtube.com/watch?v=h4aRyv4xVRw Hope this helps, Daniel Chartier |

Hello Daniel. thank you very much for answering, in TIA Portal V13 SP1 Update 4 and PLCSIM V13 simulating an S7-1500 CPU try to force the digital inputs using Observation Tables and Force Tables and from TIA Portal you definitely cannot, searching I found a Read me online document about PLCSIM V13 in which SIEMENS recommends not forcing the digital inputs (S7-1500 CPU and ET 200 SP) from the TIA Portal because unwanted behaviors may occur, they recommend that the forcing be done directly from a Simulation Table in PLCSIM, this is what I did and indeed now it works. I annex the related document.

Hi. i Think you need to Force them.(inputs) in simulation mode. |
