Hi Manfred, Thanks for the reply. The Sentron we are using is PAC3200. Regards, Manju

Hi, I think it is not possible because the S7-CPU gets the data of the SENTRON PAC3200 over the IO address range. So,the panel canonly communicate with the S7-CPU. Manual of the SENTRON PAC3200: http://support.automation.siemens.com/WW/view/de/32497295/0/en Bye |

Hi ZAK, I think what you are referring is the Profibus interface on PAC3200 which is an optional interface. I have attached a catalog which shows a standard Ethernet interface. This Ethernet interface supports MODBUS TCP. Regards, Manju AttachmentCAT - PAC 3200.pdf (274 Downloads) |

Greetings It is possible to connect Sentron PAC3200 directly to WinCC flexible, without PLC. There should be example here:https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang=en&siteid=cseus&aktprim=4&extranet=standard&viewreg=WW&objid=20229806&treeLang=en Just make a new Modbus TCP connection and use tags from the sample. Drawback is that only one HMI can be connect to a PAC3200. Which means that if you have several PCs with HMI (or panels), the one that starts first will occupy the connecition. On the other hand, I don't know how many PAC3200 you can connect to one HMI, but I don't think that this number is large. So, if you have a large number of PAC3200 managers, or several HMIs, best choice would be to use some PLC (e.g. S7-1200) as gateway. But if you have only one HMI and few PAC3200, you can use direct connection. Best regards

Sure you can, The HMI Panel acts as a Client and makes the active connection. The addressing can be a bit tricky if you are not used to doing Modbus. |

WinCCFlex 2008 has Modbus TCP driver to access values from SENTRON PAC3200 / PAC4200. Direct values are accessible by this method : https://cache.automation.siemens.com/dnl/TQ/TQ0MjgzMwAA_37450303_FAQ/68193_76.pdf Max 8 PAC from WinCCFlex Runtime Max 6 PAC from HMI Panel I gues One PAC can connect to only One Accessing device Ciao, Daew |
