Profibus, LSPM2 implementation


Thread Starter


It is our first step in Profibus networking. We use CPU315-2DP and our own IN/OUT board based on LSPM-2 Siemens (8-channel temperature to digital converter and 8-channel current to digital converter). We have connected diagnostic port to V+ and have no any OB for fault diagnose and fixing. We need it to debug Profibus network communications faults. We will be gratefully for examples or comment on usage of diagnostic port E. We also need OB program which controls Profibus communication for one node (slave) or all existing on the Profibus network. Many thanks ADAM Augustyn. [email protected] or [email protected]
