Hello guys!! I have come across a problem with connecting two modules (CP 342-5 FO and ET 200M station with IM 153-2 FO) via Fibre Optic protocol. Briefly, what I'm ought to do is the following (see attachment enclosed for futher details): 1. I'm using an S7-300 microcontroller (CPU 313C). 2. I have got a sensor with an FO plug, the information from which should be processed through ET 200 M Redundant module. 3. ET 200 M (DP Slave) connects to the CP 342-5 FO (DP Master) module in DP master mode. 4. I should monitor the information from the sensor on the PC station. What i have done: I have plugged everything in (power and connection cables - PROFIBUS, PROFIBUS FO, MPI USB), configured the system in STEP7, downloaded configuration to the CPU. What problems i face: I can't establish connection between these two stations (CP 342-5 FO - ET 200M). The RUN LED lights green on both modules (RUN on CP342-5FO and ON on IM 153-2 FO). The BUSF light is flashing red on both modules (BUSF on CP342-5FO and BF on IM 153-2 FO), which means - as i have read in the manual - "Running (RUN) with DP slave error". There's a report I enclosed you may look through. I would appreciate it if you helped me with this issue. -- Sincerely, Paul Maslov, MSc R&D Institute for Electro-Physical Apparatus Mobile: +7 (951) 672 22 19 Phone: +7 (812) 461 01 01 Attachmentreport.pdf (147 Downloads) |

Hello maslick, please check the diagnostic buffer of the CP. Have a look at the special diagnostic of the CP too. You could start it from the hardwareconfiguration options of the CP -> special diagnostic. Maybe you could publish some screenshots of the information there? Have you programed the FC's that are necessary for data exchange between the CPU and the CP (DP_SEND and DP_RECV)? What's about the status of the FC's? At this page you will find examples for a configuration of a CP 342-5 as DP-Master: Quickstart Good luck Sabine
