![]() NetToPLCSim uses the S7ProSim COM-Interface of PLCSim, to read/write the data out of it.Ī background thread waits for connections on port 102 and handles the S7 communication (ISO on TCP). It will work with any other driver that uses S7-Communication (no configuration or programming in the PLC is needed), and uses no special functions. ![]() ![]() ![]() Nevertheless you can read/write this data. But you can't browse the PLC with the OPC-Scout, because it asks the PLC which data blocks are present in the PLC. If you have large amounts of data and many cyclic data for alarming, WinCCflexible requests the PLC to send cyclic messages with this data without any request from flexible. Siemens Step 7 is a powerful integrated software solution for automation, and includes the programming environment for Siemens programmable logic controllers (PLCs). * Siemens WinCCflexible sometimes uses special protocol commands which NetToPLCSim doesn't support. Introduction Siemens makes several PLC product lines in the SIMATIC S7 family. NetToPLCSim don't cares about the rack/slot specifications, and handles a max. So in your client Software (SCADA/HMI/OPC) you have set the IP address of the PLC to the IP address of the network interface of the PLCSim computer, or set the IP of your network interface to the IP your PLC will later have. The computer on which PLCSim and NetToPLCSim is running represents your PLC.
