The only reference I could find for OPC with the CP1434 was with the TCP version. I did find this link about setting up an OPC connection with the S7 before there was TCP. http://support.automation.siemens.com/WW/view/en/834139 The procedure should be similar for the 505 CP1434TF. Disregard the references to WinCC. I no longer have a1434, so I can't verify it for you. The CP1434 configuration software is equivalent to the COML software described in the FAQ Bill |

Thanks for the reply, but that did not work. Not sure what to do next. |

As far as it doesn't work goes, the CP1413 and CP1613 are basically the same except for the bus, ISA versus PCI. H1 or ISO is the same protocol whether it is on a CP343 or a CP1434. A TSAP is a TSAP. With more details I may be able to help! Send me your configuration on both ends. An alternative is to replace the CP1434 TF with the CP1434 TCP. I have seen those on eBay for between $800 and $1100. You may be able to getthe TF upgraded to TCP by sending it in to Siemens.You could also replace it with a 2572 module from Siemens or CTI. I have seen them on eBay for between $750 and $1850. I have also seen third party OPC servers advertising H1 protocol like http://www.er-soft.com/files/INAT_OPC_Server_100-3100-01.pdf You can find more with a Google search using "OPC Server H1" although I haven't found one that expressly says 505-CP1434TF Bill |

Bill, Thank you for the help. I am attaching a zip of the Step 7 project I am used to set up the OPC Server side, I am using Simatic NET and the H1 file that I used to create my TSAPs in the CP 1434TF module using the 505 CP1434TF H1 Configurator. To provide you with a little history.. I work for Siemens COC center. I am working on a project to upgrade a customer from their present HMI to WinCC 7.0. They currently have a TI 555 processor with a CP1434 TF module, and use the Layer 4 H1 protocol for communicating to their present HMI. Now I can get WinCC to communicate to the PLC using the built in Simatic TI Ethernet Layer 4 driver. That works good for analog V registers, but seems to be having problems with Control Registers. I was thinking that if I could simply change the communication to OPC, I would be better off. The issue with the Control Register has become a project road block.

I made some changes to your project. I added an other station and named it 555. You will have to edit the MAC address. In Netpro I added a connection to the PC Station, named 555-OPC. I chose the ISO transport since this is not an S7 connection. The default was for an active partner. You may have to change this to NO You will have to go into the properties of the connection and change the TSAPs to a) what you wantor b) make sure the CP1434TF TSAP matches the NetPro or vice versus. Download the NetPro connection to the PC Station and download the CP1434TF config to the module. Let me know how that works out. Bill AttachmentSiemenso.zip (931 Downloads) |
