Hi, In your last post I answered your question about connecting hardware signals to structure signals. (how to get rid of STRUCTURE data type in CFC - Entries - Forum - Industry Support - Siemens) I created the simple logic for you. See attachment for the implementation. So to sum up: I0.0 is connected to channel driver Pcs7DiIn. The output is connected to a MonDiL (which can show digital signals at the HMI for you). I set Color parameter to "1" so in case the Ready signal is TRUE, color red is shown in the block icon. An alarm is created as well. The input signal from the channel driver block is also connected to a interlock block. The "InvIn01" is set because the input should be inverted. If "0", the interlock must show "1" at Out parameter. The output is connected to an OpDi01 block which is an operator block with a button that can be pressed. If the Intlock signal is "1", the button can be operated. So if the input signal I0.0 is changed to TRUE, the operator button cannot be operated and a lock symbol is shown. After the button is pressed, the output is connected to another MonDiL, to show an active signal at the HMI. I set AlmMsgEn to FALSE because otherwise an alarm would be generated. The output of the operator blok also goes to another channel block which is Pcs7DiOu which is used to set a hardware output signal. In this case Q0.0 is being set to TRUE. I used standard APL blocks. But if you do not want to use the standard block icons and faceplates, it is also possible to use the tag to connect to your own HMI objects. So the OpDi01 and MonDiL blocks create the tagnames for use in WinCC. You can just "pick up" the tagnames in Tag Management. You must deactivate the "Create block icon" option in the block properties if you do not wish to use the block icons from the AP Library. Good luck! Regards, Sandor |
