Some progress with this, I have done the same setup using a NJ301-1200 PLC and this is not showing any error and is communicating with the SEW drive correctly. The error I am receiving on the NX102 PLC suggests replacing the CPU, not really something I want to do as this is a new PLC. I have attached the XML file for the SEW drive, would it be possible someone would have an NX102-1*** series PLC that they could download the same simple Ethercat setup as above to see if the same Error occurs?    Thanks     SEW_DFE24B.xml

Hi, I am having trouble with the following hopefully someone can help. Equipment Omron NX102-1220 PLC, SEW MDX61B MoviDrive B with DFE24B EtherCat Card. I am trying to control an SEW Servo Motor via the Omron Ethercat connection. I have connected and configured as below image, at this stage there is no errors with the PLC When I try to add a Motion control axis I can set it up as below but when I download it to the PLC I get the following error I have then reversed all of this and added an R88D-KN drive and this downloads fine.. Any ideas what I'm doing wrong? Thanks

@Michael Walsh Thanks mate.

Hi @IO_Rack We have regularly used the VPN to access PLCs for programming changes but I am confused how I can use the same method to connect to PLCs together?  I'm guessing there is away of setting up port forwarding on both routers if I have a static IP at each side? What I am trying to do is basically send alarm data to a second PLC which is approximately 50Kms, and have this warn the operator and slow down the equipment. Thanks

Hi @PMCR could you please upload the files you have referred to above.  I am trying to do this with an NX to NJ PLC via an internet connection.   Thanks

Hi Can anyone help with some documentation to setup communication of two Omron NJ/NX PLCs via the internet?   Thanks    

Hi guys I am fairly new to Sysmac Studio so reaching out for some help. I have used a union to successfully separate a Word out into its bits, bytes.  Can't get my head around how I separate a byte into two nybbles?  Can anyone suggest an easy method? The byte of data made up of an error code in each nybble. Thanks

Hi mate, Yes the control word is a fixed value.  The data is available in the CSV file it just changes the data layout from a return every 16 words to every 5 words, but only on the last stack that is written. Yes the FWRIT is preceded by NOT A343.13 I have attached a copy of the program if you have a chance to have a look, hopefully its something obvious which I am not seeing.   Thanks for your help 2020-04-26 - Deflection Rig Mobile.cxp 2020-04-26 - Deflection Rig Mobile.opt

Hi guys anyone any ideas for me? Thanks

Hi Can anyone please help with the following issue. Equipment  PLC - CJ2M-CPU33 Setup is being used to log distance measurements from a conveyor belt to a compact flash card in the PLC I have successfully set this up and it is working by writing values to a stack then when this is full, changes stack and writes the data in the previous stack to the card. The FWRIT command has the control word #3D00 (Comma-Delimited, Return every 16 fields, Append, Memory Card) The problem I am having is with the data in the CSV file, I am logging typically 300K lines with 16 values.   Towards the end of logging the data in the CSV file will start to return every 5 values instead of 16 which is just painful to re-format. I have attached an image of the Excel data to explain better. My Two stacks are  Stack 1 - E0_0   -   E0_16003 Stack 2 -  E0_16010   -   E0_32013   Thanks for any help.
