  1. NS Recovery

    Just to update -- my CF card was defective, i formatted a new card and could get 8.95 to update correctly.
  2. No of nodes can be used on CJ1W-EIP21

    How are the devices going to be connected? Implicit connection (class 1) or explicit (class 3). If using class 1 256 tag sets are available, each device may require 2 tag sets one input and one output, so 128 devices would be possible. If you have input only connections more devices would be possible. 40 nodes should be no problem on the cj1w-eip21, however you would not have enough connections using the build in ethernet/ip port on the cj2m.
  3. NS Recovery

    I've been unable to get version 8.95 to restore correctly on  NS10-V2 screens, however it works fine on NS5. The screens lock up at "copying system files" and the indicator light either stays solid red or off. Version 8.6 is the latest version that i can get to restore correctly on these screens.
  4. NS Recovery

    Just tested an old CF card and formatted with linux. It certainly does work. Are you copying the files to the root directory on the CF card? Clear any partitions on the CF and create a new empty MBR partition table. Then format to fat16 -> ie sudo mkfs.msdos -F 16 /dev/sdb  
  5. Q03UDE- CPU Built in Ethernet error

    I'm no Mitsubishi expert by any means, but after so much time i think you should replace CPU and not worry about getting service. I think you have exhausted all avenues to get your existing unit working. 
  6. Q03UDE- CPU Built in Ethernet error

    Hi @madhan looking at the screenshots the MAC address of the unit is FFFF.FFFF.FFFF . This is a broadcast address. The MAC address would not be user adjustable so you may have a defective unit.  
  7. Q03UDE- CPU Built in Ethernet error

    Sounds like direct connection uses a layer 2 connection, and connection via hub uses layer 3. Although you can connect when connected directly what do you receive when you ping the IP address of the PLC? What does the output of ipconfig /all produce when connected via the "hub/switch". 
  8. Q03UDE- CPU Built in Ethernet error

    Are you using hub/switch/managed switch? Are you able to communicate with any other devices connected to the hub? Which devices support auto mdi-x? (auto crossover) Are your cables straight through or crossover?  
  9. Using DHCP in the OT Space

    IT can be your best friend or your worst enemy. Far better off working with them.  Port mirroring from remote switches, remote access just to name a few.   
  10. Have you looked at manual W565? According to the manual it's working as intended.
  11. NX PLC Comms To Flexisoft GENT

    Input data length when reading datasets 1-4 is 202 bytes. I also found an issue with ethernet/ip on this module when writing data to the module. Do not use bit 0 of the first byte. Bit 0 does not work.
  12. Good luck with your testing. But with only 110uS system overhead to play with I don't like your chances. Adding ethernet/ip comms, and a 10ms periodic task. I hope you don't have to much code to put in the task.
  13. PB32 wasn't supported on W10 either and the ways to get it to run wasn't really supported. Why not set up a VM and install it on a supported OS?
  14. If it's working fine on a Siemens at 5ms main cycle, why would you want to run at 0.5ms main cycle time on the Omron?  
  15. Control FR A800-E over Modbus with Beijer PLC

    Yes very strange having the same register as the control / status 
  16.  Serial device servers work really well. Run ethernet to each RTU and install the serial device server at the RTU. This future proofs by having ethernet at the device, and in the short term serial cable can be short.
  17. Yes it is a bug in sysmac, and is inconsistent. Not all devices behave the same. Some Install and you can find what the device is from the connection manager, others just get removed.
  18. Monitor Ethernet IP devices on CJ2

    Nice work, and thank you for posting your update.
  19. Monitor Ethernet IP devices on CJ2

    Yes in a class C or 255.255.255.0 (/24)  network it will go by the last octet.  If you have the devices registered in the scan list you will see the corresponding bit/node "high" in the address range n+16-19. These addresses will show you the nodes registered to the EIP module. If communications are established with the target node address you will see the corresponding bit go high in the address range n+20-23. Bit's in the range n+20-23 will go high or low when communication is up/down    
  20. Monitor Ethernet IP devices on CJ2

    Providing the node address of the slave devices you want to see the connection status of is less than 63, you will be able to see the connection status flags in the CIO memory. The base address is calculated of the unit number CIO 1500 + (n x 25). Within this block of 25 words you will find the connection status in n+15-19 and n+20-23 so CIO 1516 - 1519 and CIO 1520 - 1523 if the unit number is 0. Each bit represents 1 node, so the 4 words can show the status up to node 63.
  21. When this error occurs it actually removes the device from the list when the project is imported. Then only way i found what was missing was to go through the code looking at the comments and tags. For me i was missing an EDS for a "E&H promass flow meter" I can't reproduce the error now i have the EDS files installed.
  22. Monitor Ethernet IP devices on CJ2

    In manual W465 section 4 you will find the memory allocations for the EIP module. You will find the status flags for your connected devices in these areas.
  23. RECV command in CP1L-E from NJ-301 in different subnet

    In your device you are performing the recv on you will need to add an entry in the fins/UDP tab. This is where you can map a fins node address to an ethernet address. Fins addressing on a local network is based on the last octet of the ip address, however when trying to reach a unit on a different subnet you will need to add the mapping. If the NJ is the device your trying to RECV from you will need to set up the source data as  CJ memory addressing by using the "AT" address translation. Some processors you have to enable the CJ memory areas. 
  24. RECV command in CP1L-E from NJ-301 in different subnet

    If your able to connect to both plc's without changing your workstation ip it would suggest that the default gateways are set and there is a route already in place.
