Dear The Brain, i think we can solve this problem with OPC my expectation and i have tested some devices solution is here. http://www.softwaretoolbox.com/Prod_Services/OPC/OPCServers/opcservers.html I know that the OPC connection has also limitation it will only 8 but we can creat multiple connection for multiple devices in one OPC connection as well in WinCC flexible. Thanks, Regarded. |

Yes, Gateway needed for the conversion of RTU Modbus RS485 to Modicon TCP/IP configuration in WinCC flexible see attached scheme after that you will design the number of screens with minimum I/O fields on one screen with at least 1 minute refresh rate for each tag otherwise some time I/O field tag change it's state from 12345 to ##### AttachmentLayout.pdf (223 Downloads) |

"RTU Modbus RS485 to Modicon TCP/IP configuration in WinCC flexible" This made me again confusion. Configuration in Wincc Flexible via OPC or Modicon TCP/IP? You can use Modicon TCP/IP with one Serial RS485 to Eathernet Gateway with unique IP BUT Only for 32 Modbus Slave devices. In OPC you have to configure tag in OPC and as well in Wincc flexible if you want to use OPC you need connection configuration in WinCC flexible for OPC server in communication driver see attached. You can use OPC communication driver with one Serial RS485 to Eathernet Gateway having multiple serial RS485 connection with unique IP for up to 32 X Serial ports = Total Slave Devices From your PDF i understood configuration as: Please correct if I am wrong.Meters(Serial loop)>>>>>>Gateway{Convert to TCP)>>>>>>>OPC in PC>>>>>>>>>WinCC Flexible YES, AttachmentDesktop.zip (189 Downloads) |
