Hi, did you generate your WinCC project within SIMATIC-manager? http://support.automation.siemens.com/WW/view/en/11841504 Did you install AS-OS-Engineering? http://support.automation.siemens.com/WW/view/en/18771732 Normally you must install STEP7 first and then WinCC.... nemo |

Hi! See... roughly speaking:in WinCC you have 2 types of tags: external and internal. The internal tags are an internal memory allocation within the supervision and control system, which means they're only used internally by WinCC, so as long as the PLC is concerned, they don't even exist! The external tags are memory allocations in the controller, which means those are the ones whichstored inthe PLC. So if you have 2 tags in your PLC and want to monitor them in WinCC, they should be external tags.For the communication you'll have to use a communication driver. You'll also have to properly configure the driver... select the PLC's address in the network, and so on... |
