HelloKRS2008104567 A CP 341 can be used with its integrated Communication Drivers or Special "Loadable" Drivers. CP-341 has several integrated Drivers e.g. ASCII , 3964R , etc . In case these drivers have been used, then you can just remove the existing CP-341 and plug in the new CP-341. However several loadable drivers are also available for CP-341 e.g. In case of loadable drivers, after replacement of the CP341, the driver has to be downloaded to the module. Pl follow the following procedure : Remove the existing module. Remove the Blue Colored Hardware Dongle at the back of the old module Plug the dongle into the new module. Install the new module into the Rack. Download the Relevent Driver from the corresponding link provided above ( Pl check the version ) Download the Driver to the CP-341 ( Procedure provided in the manuals available on the above links ) Hope this helps Cheers Navnag |

HelloKRS2008104567 If there is no Dongle it should be 100% plug-and-play, right?- Absolutely right for compatible Firmware Versions. In your case Old Firmware and new Firmware do seem to have an issue. Pl Check : As per this Update : The new firmware version V2.1.0 optimizes the data throughput of the CP341-V2: To be able to utilize the higher performance you require the "Configuration Package for Point to Point Communication“ with version V5.1 incl. SP11 (see entry ID 27013524). The parameterization data for the CP341-V2 (FW version V2.1.0 and higher) must be newly generated with PtP-Param V5.1.11 for this purpose. Therefore you should regenerate the PtP Parameters for this CP341 and download to the CPU. Alternatively you can downgrade the firmware version ( I would however not recommend this ) Hope this helps Cheers Navnag |

I agree. I am currently downloading this drivers. CP PtP parametrization software http://support.automation.siemens.com/WW/llisapi.dll/csfetch/27013524/Setup_PtP_V5114.exe?func=cslib.csFetch&nodeid=81303630 ) Modbus slave drivers http://support.automation.siemens.com/WW/llisapi.dll/csfetch/27774276/Modbus-Slave319.exe?func=cslib.csFetch&nodeid=64128597) . But the mystery is, how come the previous replacement worked simply as plug-and-play while the later does not. Anyway THANK YOU VERY MUCH! for your assistance. Regards. |

Hello, it depends on the application, there is no "standard". Regards, Kaulquappe |

HelloKRS2008104567 You should check the following with a Modbus Master / Slave Simulator software like : I assume that you are communicating on RS485 / RS422 as you are having a Daisy chain. You will beed a Serial/USb to RS485 convertor for checking the communication. You can check if your CP 341 is communicating as a Modbus Slave by Setting up the Modbus Simulator as a Modbus Master and the CP as Slave. Also you can check if DCS is communicating properly by Monitoring the DCS telegrams using a Serial Port Monitoring software ( e.g. Docklight) or by configuring the Modbus Simulator as a Slave. This way you will be able to identify the problem point. One you have identified the problem point, pl post your observations here for further advise, Hope this helps Cheers Navnag

Dear KRS2008104567, it is difficult to say what could be the problem without deeper analysis. Using "ASCII" setting at the CP's explains why you don't have anydongle plugged in your CP's. Unfortunate this setting does not tell us about the protocol used fordata exchange. Maybe you can find that out from some documents. It is possilbe that a PLC software uploadwill supportus finding that out but thats not guaranteed. If nothing can be foundin the softwarea trace of thereceived data by the PLC's need to be done. That tracehas to match with the protocol description. As already written byNavnagyou will needproper hardware/software and knowledge of using these tools tobe able to localize the problem. It could be anywhere: PLC's, DCS, wiring....... Best of luck! |
