#Siemens cp341 modbus slave parameter software download manualHint The functions described in this manual are illustrated with screenshots from the TOOLBOX II. For activities, which comprise hardware manipulations, it is essential to pay attention to the appropriate safety instructions and to strictly adhere to the appropriate safety regulations. Manipulating the hardware itself, as for example "unplugging" and "plugging" printed circuit boards and modules, or working on terminals and/or connectors for instance when applying changes to the wiring are also if they are an issue in the context of configuration, parameterization and diagnostic not subject of this document. Issuing date: Siemens AG Order nr.: DCģ Preface This document is applicable to the following product(s): SICAM RTUs Ax 1703 Purpose of this manual Target Group This manual describes the function and the manner of working of the MODBUS protocol in SICAM RTUs and essentially contains: Functional descriptions The document you are reading right now is addressed to users, who are in charge of the following engineering tasks: Conceptual activities, as for example design and configuration System parameterization and system diagnostic, using the designated engineering tools Technical system maintenance Above applies, as far as these tasks do not involve manipulations of the hardware.

Please make sure you have in your possession all required elements for the setup of the network: CP3431 with X27 submodules Modbus master and Modbus slave loadable drivers, with appropriate dongle parammetrizing software for the Modbus interfaces and correct cabling between the Modbus partners. Sometimes there can be NDR (New Data recieved) signal synchronization to be verified, or Modbus function triggering to be checked, but at least you should have some kind of validation of the network. ![]() #Siemens cp341 modbus slave parameter software download manualsIf you have bought and installed all packages as per the instruction manuals and programming examples from Siemens, you should have at least functionning LEDs on the master and slave modules, or diagnostic LEDs available for troubleshooting. #Siemens cp341 modbus slave parameter software download driversFinally you have installed appropriate wiring between master and slaves, as per the instruction manuals of the drivers (note: this can be tricky, especially if you have other types of slaves on the Modbus network) #Siemens cp341 modbus slave parameter software download driverOn each Modbus slave PLC you have similarly setup a CP341 with its X27 interface module, installed the dongle that comes with the Modbus slave driver package, parametrized the CP341 as a Modbus interface similar to the master (and downloaded to its CPU)and inserted the Modbus slave function blocks from the driver package to respond with appropriate data to the Modbus master's requests You have then programmed the Modbus Master function blocks included in the Modbus Master driver to establish links and Modbus functions with the slaves. You have used the parametrizing software to setup the Modbus driver parameters of the CP341 (Modbus address, data speed, duplex/half-duplex connection, etc.), and dowloaded it to the CPU. On the master PLC (Modbus master) you have setup a CP341 with a X27 (RS422/RS485) interface module (since you are connecting to more than one slave) and the dongle that comes with the Modbus Master loadable driver software package. For some reason, you wish to change the connection from Profibus-DP to Modbus RTU You have for the moment 3 Siemens CPUs, connected over Profibus-DP, in a working configuration Please take a few minutes to explain your problem a little further: ![]()
