Siemens Micromaster 440 Drive with DeviceNet and Omron NSJ8

I've to control few micromaster 440 drive on devicenet. It's my first time with Omron and Devicenet network. My programme is working well in simulation, i've to find how to grab points on this siemens drive. Has i read into the drive manuel :

Read : ON/OFF Status - (Status Word 1, bit 2)
Faults - (Status Word 1, bit 3)
Current frequency - PZD WORD 2

Write : START/STOP Command - (word 1-control word 47f and 47e)
Frequency SetPoint - (PZD WORD 2)

I understand that i'll have to recieve 2 words and send 2 words, i have set the parameters P2041.01 to #120 and P2040.01 to #170. How do i send and recieve those word in CX-Programmer ? How do i set address for those points ? In CX-Intergrator i've been able to see all my Device net I/O card and it have assign Input from addres 3300... and Output from 3200. I've import into CX-Integrator the .EDS file of the micromaster drive. I see in it the 2 polling word and the 2 pulling one.

My device net network is small i got only 1 GRT1-DRT (Node 2) module with some ID8, AD2 cards and the micromaster drive (Node 3 default).

Do i have to do send/recv function has with ethernet or can i juste set address for each points that i want ?

If you can give me few hints. I wish to find exemples.

Thanks

It sounds like you are making some good progress, you must of used devicenet/CX-Integrator before?


Have you transferred the Scanner config to the scanner? This would be step 1 (after what you have already done that is)

You would of assigned some 3300/3200 areas to a 'node' in your scan list, these will be visible for where they are, but could be something like: (assuming 2words each...)
3300 & 3301 :- 1st allocated node input area
3200 & 3201 :- 1st allocated node output area
3302 & 3303 :- 2nd allocated node input area
3202 & 3203 :- 2nd allocated node output area
and so on....

You don't, the devicenet scanner does it for you (unless you need more parameters than what are available, then you go to explicit messaging...)

Ethernet?, your devices are on devicenet?
You should be able to just set the bits as required, it will take a bit of reading/testing to determine the exact config, especially for the drives (sometimes the are backwards/byte reversed)

Hope this helps you some.

I've search and when i've double click onto my PLC Device net card i've put from unregistred to registred the device MM4 and there i've see the Input/Output adresse!

Thank you!
