Hello, I am using Set Slave option of Siemens PLC with one of the Profibus PA device. It supports SSA and the keyword Set_Slave_Add_supp = 1 in the device GSD file. However, I get an error when I select option "Assign Profibus address"(Please refer attachment for the error details). Could you please help me understand what could be the problem? Thanks, Sharvari ------------------------------------------------------------------------------------------ |

Hello shorkar; I am not a designer of Profibus slave hardware, so this is technical information I am not privy to. This type of documentation I presume is provided to Profibus developers who follow the path for certification of their Profibus slaves, along with all details on the Profibus exchanges, by Profibus International (PI). What I do know (as a user of PDM, Step 7 and FieldCare) is that when you use the Assign Profibus Address (formally known as Set_slave_address) function you get the dialog box you show in your first post, once; the slave with address 126 is found on the network, the user inputs the address he would want for that slave and the dialog box closes. The slave's new address is effective immediately. One excellent document on Profibus, as it enters the parameterization level of the communication software, comes fro Acromag (a maker of Profibus sensors and instruments). The screenshot below comes from this document, and may provide some hints for your own work: http://www.diit.unict.it/users/scava/dispense/II/Profibus.pdf At one point, I followed this forum on Profibus.com, which had a section for Profibus developpers needing to get support from their peers. See if there is still help available there for your problem. Or look at the Certification documents from Profibus.com. https://uk.profibus.com/uk-pages/forums/ Hope this helps, Daniel Chartier |
