Dear All I am facing a strange problem while communicating with a Profibus PA Device. I have configured a Profibus PA Device in Hardware Configuration and set the address on the device accordingly. The Hardware configuration is downloaded with the device address. When I am going to online mode in the hardware configuration, the device shows " Device not found". Whereas the device is communicating through Simatic PDM, which is installed in the same PC/ES. I am able to perform upload/download operation through Simatic PDM. I am using S7-400H CPU with DP/PA Coupler. The ES is communicating with the CPU over Ethernet Protocol.

Hello Dhruva interesting problem (or challenge) indeed. Since PDM is able to communicate with the PA device (via routing through the S7), I'd say we can safely assume that the you don't have a physical bus problem and that the PA device itself isok. Based on this, the only obvious thing I can think of for now is that you may have used an incorrect GSD file for your PA device inS7 HWconfig. Pleasecheck this and let us know what you find. I hope his helps |
