Hello AGrS, In those situations, I suggest you use the Local Mode. Local Mode is specially designed for local operation. Like Automatic and Manual mode, Local Mode is used so a operator can control the object from a certain location. This will prevent dangerous situations like the operator controls the motor from the faceplate while standing next to the motor. It is a standard APL functionality. See the following attachment. I made a selection from the APL library on Local Mode AttachmentProcess Control System PCS7 Advanced Process Library (V8.1).pdf (115 Downloads) |

Hi, under the following link you can find a library whit Motor control module types with local operatoing mode. https://support.industry.siemens.com/cs/ww/en/view/109475748 Hope this helps. |

Please see the following diagram in attachment. You will have to set the block to Local Mode, which is basically a mode like any other: Manual and Automatic. You can exit the local mode by two ways with the use of the featurebit 10: If FeatureBit 10 = 0, You can exit from Local to Manual mode If FeatureBit 10 = 1, You change back to the mode which was last active. There are multiple possibilities for using the local mode which is presented by the LocalSetting parameter: Local Setting 1 and 3: Control settings are made by CFC logic, runtime monitoring is active, Interlocking functions of the block are activated in accordance with input parameter ByProt = 0 or deactivated (ByProt=1). Local Setting 2 and 4: Control settings are made based on internal adjustment of the feedback signals and runtime monitoring is disabled. I suggest you look at page 74 of the attachment. It lists all possibilities. If you want the full manual, please see the following manual: PCS7 Advanced Process Library (V8.1) |

Hi AGrs, It looks like this is a custom block?? I don't think it's coming from another APL library by the looks of it. |

Hi, Well, I don't know this library. Could you tell me a bit more, do you have a manual of this library? It doesn't look like it's an APL block. For PCS7, you only have the Condition Monitoring library and the Industry Library and add-ons CEMAT and Braumat. What I mean with custom block is a non Siemens block. For example, a user which created a SCL source. |

Hi again, Hmm, is it possible you could upload the complete manual? I'm interested in this library because I cannot find it anywhere . I want to have a look at the block inputs/outputs and functionality. For your question, I think you will need a signal to PCS7. Or you have to cut off the feedback value electrically like using a relay of some sort. Without a local signal to PCS7, but with the feedback signal of the motor, it's not possible to create the operating logic for this. The only thing to do is to set the motor to: "Out of service". Now you can start the motor locally, but feedback is not taken into account. I don't think you need the control signal from PCS7 to start the motor right? |

That is correct. But still if I set the In_Fb_On block in simulation mode and cut off the logic coming from the block I was able to get it working. Attached is the documentation. AttachmentPP_DCS_APL_AS_v010201_en.pdf (67 Downloads) |

Hi AGrs, Thanks for the document! And your first rating from me I will have to see if those blocks from paper library support simulation. You have two options for simulation (in APL). Internal and external block simulation. You can use internal simulation for the block itself. For instance, when a feedback signal is not working, you can set the block to simulation and then you can operate the block like normal (in addition, you have to set one featurebit in order to send the control signal to output in case of simulation). External simulation is used to simulate specific signals like feedback signals. In your case and if internal simulation is supported, you can better set the block to internal simulation. In this case, you wont have to simulate the digital feedback signal (because you have to do this in CFC). With the internal simulation, an operator can set this at the faceplate. |
