CCJohnston Posts: 6 Rating: (0)	Good afternooon all, I have what is perhaps on the surface a stupid question. I have a WinCC application that is running and have no problems. Since I have all of the software S-7, WinCC and so on I would like to create a new project and use PLC Sim to run it as a reference system. However after discussing my idea a suggestion was made that if we were to have a few Digital inputs and outputs that would interface with this reference system we could then use this as a training tool also. My question is this: Can I run PLC Sim and interface with an S-7 200 over a MPI or Ethernet at the same time in the same project? On the surface this seems very feasable, but would like to verify. The main reason for wanting to use PLC SIm is for portablity. I only need about 2 words of I/O, then I could mate the PLC up with a laptop. Thanks for your help.

Danielle Posts: 1275 Rating: (123)	Hi, If what you're asking is if you can run PLC Sim and WinCC on the same computer, the answer is yes. You'll just have to set up an MPI communication on the WinCC side. This is a very good tool for simulation and training indeed. Just be sure to always check compatibility before installing any other Siemens software. Best regards, Danielle

CCJohnston Posts: 6 Rating: (0)	Yes I understand that we can run PLC Sim and WinCCat the same time. In addition to that, is it possible to run the simulation for the logic and mate it up with a S-7 200 via ethernet? This way we can toggle on digital inputs to the project. The idea is to have an external input to trigger various funtions within the WinCC project. This will allow us to create a training tool that an opertor can use, with out all of the need for the normal Digital outputs. See and feel buttons working and so on. Thanks

Danielle Posts: 1275 Rating: (123)	Hi, We've done this with S7-400's and S7-300's with no problems... The PLC's had simulation logics, and we just left VAT's available to force values... I don't work with Microwin, though, so I won't say much about the S7-200... Best regards, Danielle

Nemo Posts: 3149 Rating: (171)	Hi normally PLCSIM simulates S7-300/400 - JUST via MPI, not via Ethernet. For simulation of I/O or setting up an operator training you can use e.g. simit http://www.industry.siemens.com/siemensindustrialservices/EN/SOLUTION_SERVICES/INDUSTRIALIT/PROD_LOESUNGEN/TESTSIMULATION/TEST_SIMULATION_SIMIT.HTM nemo

Danielle Posts: 1275 Rating: (123)	Hi Nemo, We usually make our own simulation blocks... Creating our own simulators isn't hard, but they never get as complex as the actual plant. What they usually lack is a good loop simulation... I haven't tried Simit yet. I've just registered and am about to download the demo, though. How far does it go when it comes to simulation? What kind of interfaces and tools do we get with it? Best regards, Danielle Edit: I've just researched a little further, and found that Simit is an add-on for PCS 7.

Take a look @ PLCSimCOM interfacedocs and make a small VB OPC-Clientprogram that handle back and forth those I/O words between a local/remote S7-OPC Server and PLCSim.OPC Server needs a connectionto S7-200 (over Ethernet perhaps). See EM277 docsfor details on how to configure a connectionwith S7-200 over Ethernet. See Simatic NETfor S7-OPC VB Client example. See PLCSim docs for theCOM interface example. In ~ 1 hour you should be able to get the data from S7-200<-> S7-OPC<-> VB App <-> PLCSim <-> WinCC. Dec P.S. I prefer Woodhead (SST) PICS I/O Simulation. It'sthe best simulatorI've ever used.

Danielle Posts: 1275 Rating: (123)	Thanks for sharing, Dec! I'm getting the Woodhead PICS demo now... I'll try to find some time to test it. Best regards, Danielle

Is possible create a similar tool, directly in the WinCC. Ihad already discussed with another user: /tf/WW/en/Posts/6951

Danielle Posts: 1275 Rating: (123)	Hi Márcio, We use our own blocks as well... and we simulate all of the process, but parts of it could have a more realistic touch... so I think a simulator might help with the control loops and overall process information, getting them closer to reality. That's why I'm gonna give Dec's software a go, to see how far and well it goes on this matter. Best regards, Danielle
