You can use MV_TrkOn"". If you set that, the MV is tracked to the input value: "MV_Trk". In your case set "0.0". After releasing-> MV_TrkOn=FALSE, the MV will start increasing again. |

Hi Alwin, Oops, for a moment I thought you were using a PID block (Conl). Anyways, It looks like the block is coming from pcs7 6.1 version or maybe 7, because I see that the variable names are old ones like spexon_l and "LMN" is used instead of MV. I can see that there are "LMN_TRK" inputs. I don't know the block, but in the old PID blocks you use LMN_SEL to enable tracking and LMN_TRK is the value in tracking. It is the same functionality like the names I gave you before. There are more tracking values you can enter (LMN_TRK1,2 etc). I don't know how this operates. |

Hello Well, the block is not part of the APL library (Block and FB number not known). While searching it could be coming from SIPAPER. The instance DB is generated automatically by the way. OK, you have to check which tracking value has highest priority. For example, when In01 and In02 are both active, which tracking value is set? You can then determine where to set value 0.0. What you have right now is that when In01 is set active, the MV value is set to LMN_TRK1, so the MV value is tracked and your controller stays at the same MV. If you delete the interconnection to LMN_TRK1 and set value 0.0, the next time In01 is active, value 0.0 is sent to MV. When In01 is not active, the controller starts again from 0.0 |

Hi AlwintGru, I don't know exactly what you mean with: "Download does not catch the PLC" You can get online with CFC editor? I personally never use the compile objects screen. Normally, I open a chart in the AS program. I then click on the download button (see attachment in the red circle right symbol), you can select a compile (change or full) and then download change of download full. Next, If you can get online (symbol in blue circle), then your PLC program is OK. Then compile OS+ download OS. |
