Dear All, At present we are trying to communicate between Siemens DP/DP coupler (6ES7 158-0DA01-0AX0) and Allen Bradley SST_PB3_CLX module.
Customer ->Our PLC(16 Bytes) configuration set in Allend bradley side is attached for your reference. please go through both and let me know is there any changes required in allen Bradley configuration side inorder to establish communication. at present the siemens slave is not at all visible in the network created by Allen Bradley. Your quick response will be very helpful to us to solve this issue. Best Regards, Ravindra. AttachmentC:\Users\ravindra.ve\Desktop\Profibus Connection.pdf (541 Downloads) |

Hello Suhas; To better help you out, we also need to see how the configuration of the DP/DP coupler has been done of the Siemens side. Both DP masters must have the DP/DP coupler as a slave, and module configuration must use the same size of data while byte orders must be reversed between the 2 configurations: if the SiemensDP-master holdsa configuration for the DP/DP coupler of 32 bytes OUT/16 bytesIN (as described in your post)then the SST DP-mastermust be setup as 32 bytes IN/16 bytesOUT for its DP/DP coupler slave. Have a look at the example configurations in the following FAQs, it might clarify the issue: What are the special features of input/output addressing with the DP/DP coupler? (speciially figure 02) Configuration of the I/O Data on DP/DP Coupler Are there any diagnostic LEDs on the coupler or on the CPU when you try to connect them? The Siemens PLC has a diagnostic buffer that can help locate the error, and I remember that the SST configurator could go online to see what the DP-master is complaining about. Hope this helps, Daniel Chartier |

Dear chartier, Thanks for your response.we have 2 panels with the same configuration. We were able to successfullt communicate with one coupler. Other coupler with profibus address 5 is not connecting. On the dp coupler we are getting sf1, bf1, on1, sf2, bf2, on2 all leds are blinking and on cpu314c2dp sf and bf led also blinking.. iam attaching the diagnostic messages for your reference. Please go ghtough that and let me know is there any way to check the healthiness of dp dp coupler. Thanks.

New question published by seckousagna is split to a separate thread with the subject Establish a Profibus communication between Allen Bradley ControlLogix 5550 via a SST PB3 CLX module (master) and Siemens S7-300 CPU314C-2DP (slave). Best regards |
