  1. EthernetLink.gxw   I have posted this example in the past. It is not using SOCSEND/RECV  but using the GP.READ i was able to get reliable communication between 2 PLCs. Only requires the one PLC to be modified, and you pick what addresses you want to read/write to on the other PLC. 
  2. JP.Read QJ71E71-100 Channels

    I would probably setup the various connections in different D addresses, then use a timer/step logic to connect to each one by one. I think you'll be surprised how fast it still is pulling the data. 
  3. Q to Q Enet Comm - GP.Read Instruction Error

    Gambit is correct.  In my example that you used, I was reading from Network 3 (D2004), Station 1 (D2005)  with Your PLC Settings, you should be reading from Network 1, station 2   Also in my example, under OPEN SETTINGS, I was setup as [ TCP, Unpassive, Receive, No Procedure, Disable, No Confirm, 20512 ]  You have Send and Confirm.   I dont remember exactly what those settings meant but I know I have it working..    Direct Ethernet connection is fine BTW. No switch or crossover is required. 
  4. VPN Advice

    I have not used personally, but I have tested the system from Ewon VPN Systems.  They even have a Mits demo online to play with
  5. Minimizing OR function

    The above will work, but just to give you more options.. I have been a fan of the NOT-NOT style rungs for large groups of OR.   |/A|---|/B|---|/C|---|/D|---|/E|---|/F|---|/G|---|/H|---/----(OUT)
  6. ethernet comms between different networks?

    you do have the subnet set to 255.255.0.0 in all PLCs right?  You mention a test leaving it blank, but i think that would actually default it to 255.255.255.0
  7. ethernet comms between different networks?

    I have never used the function block method, but I would bet the Station number still matters, so verify the network numbers match and station number should be unique for each PLC.    "Only get the plant friday night"  -- this sounds all too familiar hahahaha  if you have some extra PLCs laying around I highly recommend setting up a test bench, that was the only way i got the communication worked out. 
  8. ethernet comms between different networks?

    Assuming your entire network is 192.168.*.* based, if you are on a 10.25** network that might be an issue.  I believe you would setup each PLC to be network 1, station 1,2, and 3. Then use [Station No <-> IP address] to point the stations to the other IP    then using your  GP.READ you setup which station you are reading from. 
  9. How to make a recipe?

    That PDF is incredibly detailed.  
  10. GT 2000 down convert to GT 1000?

    Utilize project only allows me to select another GTW project, not the GTX project from my GOT2000
  11. GT 2000 down convert to GT 1000?

    Downgrading because I am trying to copy the screens of an existing system to create a new one, but we parts bin shopped and I have 4 GOT1000's to use. 
  12. Does anyone know a way to convert GOT 2000 screens to a GOT 1000? 
  13. mitsubishi software

    I came from using Yaskawa and Omron PLC, and learned the mitsubishi in about 6 minutes.   One look at the Insert menu will show you every keyboard shortcut you will need
  14. I have a feeling that I know the answer, but wanted to check for confirmation.  See attached for a quick example of what I am talking about.  New machine has a SM410 .1s flicker to a INCP to count time passed and stop a conveyor.  I think a H Timer would be more precise but without knowing the deep insides of the PLC I can not be sure.    In the code i have done a test where I have 2 H timers that are .2s longer than set time,  I use the longer one to compare where it was when the flicker triggers the stop,  and it does vary 
  15. Winner winner.   After 1 hour going through everything again I found that issue.  The second PLC card is setup and addressed as 200, but the TO/FROM command required it be H20  and always require to drop the last 0.
