Hello Boost34, you can create an input/output field in the Graphics Designer and connect the relevant tag. If you need more information have a look in the following manuals: Operator Station: https://support.industry.siemens.com/cs/ww/en/view/109746516 WinCC: https://support.industry.siemens.com/cs/ww/en/view/109746340 |
Kind regards |

Hi Boost34, The easiest thing to do is using Op_D and Op_A blocks. Op_D is a digital block, standard Siemens and when the OS is compiled, they necessary I/O is available in WinCC. The same goes for Op_A, which is an analog block. There are also variants like Op_A_Lim, where you can add a low and high limit so that the value is limited to max and min limits. As you already mentioned, the Multiply, Substract and Adder blocks do not have OCM capability. So, a tag is not created automatically in WinCC during compilation. There is a difference in OCM for blocks and for parameters. A block must have OCM if you need this for WinCC, but also parameters can have OCM. So, not all parameters of a block are sent to WinCC, only the ones with attribute S7_m_c:=true;. |

Thanks Oreca! I just want to add a small hint: The blocks mentioned are part of the Advanced Process Library. And the correct names of the blocks are OpAnL/OpAnS and OpDi01/OpDi03 If needed, here is the link to the APL manual: https://support.industry.siemens.com/cs/ww/en/view/90682917 |

Hi, The topic starter mentioned that he was using the older library (it's V7.1 SP4 instead of V6.1 but ok) rather than APL, so I gave the old blocks names. |
