Hello tometrajkov, if I look around in your posted threads I'd say be go a little bit in circles, so I will try my very best to give you some hopefully helpful answers. 1. Please look at answer to this one of your threads. 2. Maybe this What steps are required to start up a WinCC station as OPC server or as OPC client (OLE for Process Control)? will help you. 3. How can WinCC exchange data with Microsoft Excel or Access? DDE channel will not be supported any longer, please compare with documentationof WinCC V7.0 SP2 (WinCC Information System ("Online Help")/First Steps/What's new? If there still should be open questions please let us know Best regards Bizur |

not sure but found a unitronics manual describing Mosbus TCP/IP: http://www.unitronics.com/Data/Uploads/VisiLogic_Software_New/VisiLogic%20-%20Function_Blocks.pdf depending on the info in there about, you should make the choice between "Area with CPU Premium/Micro" or "Area with CPU984, Compact, Quantum, Momentum" I would just try them one-by-one but can't help you in detail. You should have both Unitronics Modbus manual & WinCC ModbusTCPIP manual. |

Unitronics supports both Modbus RTU/Modbus IP and OPC connection. Modbus is a functional block and can be found in their programming software VisiLogic > in FB's menu. In VisiLogic > Help menu > Examples you can find working demoes for the nessesary settings. As Unitronics needs to be Slave, you need to review thhe Help topic Modbus > Slave addressing. The easiest way to find the topic is via Help dedicated to FB Modbus. Unitronics OPC server (UniOPC) is free of charge (as all thheir software tools!) and can be downloaded from their site www.unitronics.com. It comes with detailed help. My advice - send mail withh your questions related to the PLC to their support team at support@unitronics.com. I'm not sure they can help you with WinCC, but for sure you will receive detailed help about their PLC within 24 hours! |
