Hello, My question is exactly same an unanswered thread before. There is only difference is the model of the relay. I want to connect the S7-300 PLC to a protection relay(VAMP210) with Profibus DP protocol.In this relay I have two communication mode "continuous mode" and "request mode".In continuous mode all the time the relay sends all information which I set on relay before to profibus master,but in request mode it stands for every request of profibus master and answers to it.Now I want to know with S7-300 PLC which mode can work? So what is the request mode for profibus DP? I need help it is urgent. Thank you... AttachmentVAMP210-ProfiBus3-66.PDF (60 Downloads) |

Hello Citizen2222 let's start with a general statement:A DP Slave is a DP Slave and providing it is compliant with the Profibus DP Slave standard (certification is unfortunately not mandatory for DP Slaves), any and all features that the manufacturer put into the DP Slave can be used with any DP Master. Having said that, DP Slaves canbe DP-V0, DP-V1 or even DP-V2 compliant which in simple terms introduces thefollowing functional levels (see also Profibus System Description from http://www.profibus.com/nc/download/technical-descriptions-books/downloads/profibus-technology-and-application-system-description/display/for more): - DP-V0:Cyclic data exchange and diagnostics - DP-V2: DP-V1 plusIsochronousmode and Slave to Slave data exchange |
