Hi! I'm trying to configure a Scalance S612 to use between my two networks. One is a factory-network and one is an office-network. The function I want is just a VPN-tunnel. No traffic should be allowed through the scalance exept the VPN-tunnel traffic. I've managed to configure the VPN with certificates and such, so my VPN has the function I want. There is only one problem. Both my networks use the same range of IP-adresses. 172.16.13.X The problem is that I get a IP-collision warning in windows on the office-network computers. The Scalance is now configured in bridge mode and I guess thats why I get this IP-collision. But if I try to configure it in Routing mode I can't use the same IP-range on my internal and external networks, I then get a warning when I try to download. Is there any way I can configure it differently to get around the problem of changing all IP-adresses on either my internal or external network? Thanks! Best regards, Jonatan

Hi! I'm having troubles with a application I'm working with. I have done a test station that is 99% working at the moment. The CPU used is a Q03UDE with a extra Q2MEM SRAM card. With this card I'm using Z-Registers to do data exchange with a OPC-Server. My problem is that the Q03UDE is full at the moment. The number of steps is maxed out so I have to change CPU. When I change to a Q06U and define the memory card as in the Q03 Project, all setups differ. I can't choose to latch the extra file registers. I have several different boxes and options that are greyed out even if I have the same memory card defined. I've started the test station with the Q06 but things are acting wierd, I get false values in my ZR and my sequences act strange, so stuff isnt working at all. Why is things different with my new Q06 then my Q03UDE? The settings I have entered for memory card is the same but I don't have the same setting options on "PLC System", "PLC File" and "Device". Any ideas? Hope I've explained so that you understand my problems! // Jonatan

Hi! I´m having some troubles when trying to make index of Z-Registers. I have a extra memory card and for the application we need a lot of registers, so I'm using ZR. But when I start making indexes, for example to the HMI, I get really strange values in some of my registers, i have declared som registers as REAL to the HMI and when i do an index on them I get the value 'NAN' in some random registers. I have never seen a value like 'NAN' being written and especially not in a REAL-Format variable. Anyone has a clue what this means? I'm pretty sure that it has to do with the setting in "PARAMETER->PLC->DEVICE->Indexing setting of ZR-Device" where I can input a value between 0-18. Depending on what I write here, the value 'NAN' gets written in different ZR:s? With some values chosen, some registers gets overwritten by null (''). I have called Beijer support in Sweden on this but there is seriously no one there who even knows what this parameter does! So now I'm turning to the real experts :) And another thing I came to think of, in Siemens-systems, you can't index registers with 32-bit variables, and at the beginning I used an INT, so I've changed it to a DINT but still the same problem... Sorry for my bad english, if there is something you don't understand, please let me know and I'll try to explain! If you can think of anything, please answer!!! Really need to get this working now!
