Hello Dutta; Sorry, I've never done a Profibus connection between an Altivar 61 and a Siemens PLC. But I have worked a few times between Altivar drives and non-Siemens PLCs over Profibus-DP, and never had great issues, as long as I kept the Altivar manual close at hand. Schneider makes quite acceptable litterature, at least on that aspect. Now, the Profibus manual for the Altivar 61 can be found here: http://www.download.schneider-electric.com/C1257307002C052F/all/5745E51F6F7F724CC1256FC4002D7A1B/$File/1755873.pdf and contains this statement: The Profibus DP card for Altivar 61 / 71 drives only supports Type 5 (Byte-String 28) cyclic frames in PPO (Parameter Process Data-Object) format. Type 5 PPO cyclic frames feature 14 periodic variables that are used for 2 types of service: - I/O exchanges (PZD) - Aperiodic exchanges (PKW) for parameter setting, configuration and diagnostics So you need to setup PPO5 for the drive in the HWConfig; this uses a 28 Byte (or 14 Word) size frame, including the first 4 words for PKZ comms, which you won't require here (as per a further statement in the manual). Once you have the input and output addresses for your PPO5 drive in the HWConfig, it is easy to locate the position of the different data in the Profibus exchange: Outputs (PQWxxx) :The control word starts at word offset5, the speed reference starts at word 6 of the output addresses reserved Inputs(PIWxxx): Thestatus wordstarts at word offset 5, the speed feedback starts at word 6, and the configured 8 data you assign on the driveare available at words7 to 14 of the input addresses reserved See the table page 24 of the said manual. Study the documentation, if you need any more help come back to the forum. Hope this helps, Daniel Chartier |

Hello DUTTA, Sorry but I can't find exactly parameters of drive. But you ust only follow instructions from Altivar 61_71_Profibus . And I think you are on right directions: 1.6 Command [Profile] - must be I/O profile (I O) This mean command and the target come from Profibus DP. 1.9 Communication - [COM. SCANNER OUTPUT] see page 15 in manual for more deteils [COM. SCANNER INPUT] see also page 15 in manual for more details Also is necessary and this is useful to configuring communication fault management: 1.8[1.8 - FAULT MANAGEMENT] (FLt-) menu ([COM. FAULT MANAGEMENT] submenu and assigne how to react drive in profibus failure situation. I hope this will help you. regards |
