Thank you very much Mr Ken Roach, The program works perfectly except for commands lines so I generate a MSG file for writting commands as you did for reading Currents...And it has worked. Now I can program the explicit messaging (Reading and Writting) thanks to you !

I tried to do a sample application which the master is the compactlogix 1769 L35E/A connected to the Scanner Devicenet module SDN 1769 and the slave is one device which is the MM300. You`ll find the the rsnetwork file and the rslogix 5000 file on the attached files. mm300DeviceNet.dnt test.ACD

Yes they are very new ! the PLC I`m using is Compactlogix 1769. Thank you very much for your help

Very clear explanation Mr ken Roach ! On my application I have 7 MM300, and other motor management system like F650, Softdrives (SMC flex) and variable frequency drive (POWERFLEX/VACON NX) and my scanner devicenet sdn support 90 DW (double word) and I`m afraid the information that I want to supervise via protocol DeviceNet might be greater than scanner capacity so that`s why I`m thinking to restrain the parameters that MM300 inject on the network and only choose the parameters demanded by customer

Hi Mr Ken Roach ! I am using the last version 1.5 I want not only read parameters from MM300 but I want to write parameters to it as well. The paramters that i want to read from MM300 are : Current Ia Current Ib Current Ic Pretrip current Ia Pretrip current Ib Pretrip current Ic the parameters that I want to write are : Reset Start A Stop Auto mode Manuel mode for more information refer to the communication guide : http://www.gedigitalenergy.com/products/support/mm300/GEK-113392G.pdf Thanks for your help !

I want to select and choose specific data that I want to supervise via DeviceNet protocol but in RSNETWORX it is not allowed to choose polled data that I need to read or write because they are predefined by the manufacturer [One Input: motor data, One Output: control byte] . And by editing EDS file I can just modify the Input and the output but not to add an other one and MM300 does not support the Assebly Object so I can add as much as I need for my application. So the problem is how can I select the Inputs and outputs needed for my application (3 Inputs and 3 outputs) using RSNETWORX and if there are other options please show me the way. If something isn`t understandable please don`t hesitate to say it. Thank you in advance for you help !

Thank you for this information ! I post it here because isn`t just rockwell problem but GE too (Indeed it`s my problem) :) . Anyway, I`ll post it on rockwell forum.

Thank you rootboy for your help ! the problem is more than this and i have no problem with the physical connection neither with the adress mapping (all you said about it is right), And all I want to know is how can I configure my MSG file with the writting function code 16. I wish you understand my problem !

The communication is between micrologix 1100 and GE power relay MM300, I have the following informations : performing function.bmp And the command adress is as followed : command adress.bmp And I want to write one of the following commands : commands.bmp But the problem is with the packet format, and that`t what i perform but does not work : performed.bmp Thank you in advance for your help !

I want to select and choose specefic datas that I want to supervize via DeviceNet protocol but in RSNETWORX it is not allowed to choose polled datas that I need to read or write because they are predefined by the constructer [One Input: motor data, One Output: control byte] . And by editing EDS file I can just modify the Input and the output but not to add an other one and MM300 does not support the Assebly Object so I can add as much as I need for my application. So the problem is how can I select the Inputs and outputs needed for my application (3 Inputs and 3 outputs). Thank you in advance for any insight and advice given !

Thank you very much Mr Ken Roach ! Great explanation

Thank you very much b_carlton ! Very good Explanation, wish I`ll be useful for you one day.

The informations about data that I want to write for GE device is to set mode Manuel On (exemple from communication guide). The operation code for this command (Manuel Mode) is 115 decimal. The problem is when i open a MSG file and set function 5 as a default function in the case of "target device" i have to write the modbus adress and i do not have any adress for this command and all i have is the operation code. the format of the master/slave transmission is shown below : exemple for command Reset with a opertion code=1 ------------------------------------------------------------------------------------- Master transmission l Bytes l exemple l description ------------------------------------------------------------------------------------- Slave adress l 1 l 11 l message for slave 17 ------------------------------------------------------------------------------------- Function code l 1 l 05 l execute operation ------------------------------------------------------------------------------------- Operation code l 2 l 00 01 l operation code 1 ------------------------------------------------------------------------------------ code value l 2 l FF00 l perform fuction ------------------------------------------------------------------------------------- CRC l 2 l DF6A l CRC error code ----------------------------------------------------------------------------------- ------------------------------------------------------------------------------------- Slave transmission l Bytes l exemple l description ------------------------------------------------------------------------------------- Slave adress l 1 l 11 l message for slave 17 ------------------------------------------------------------------------------------- Function code l 1 l 05 l execute operation ------------------------------------------------------------------------------------- Operation code l 2 l 00 01 l operation code 1 ------------------------------------------------------------------------------------ code value l 2 l FF00 l perform fuction ------------------------------------------------------------------------------------- CRC l 2 l DF6A l CRC error code ----------------------------------------------------------------------------------- I will be grateful for your help !
