  1. GOT 800 Upload Connection Failure

    The electrical department miraculously found a laptop still running Windows 95, I know right?! It is my lucky day. I also found a copy of the GOT program on a CD drive after digging around. I don't know how I'm getting so lucky! So I haven't tested the communication yet, nor do I really want to mess with it anymore, but I might if I'm bored. I will start on the upgrade process though now that I have the screens.
  2. GOT 800 Upload Connection Failure

    GOT: A8GT-70GOT-EW Software: SW3NIW-A8GOTP Version 20N (downloaded free off Mitsubishi website) Communication cable: AC30R2-9P (rung out pins to test and was recommended in GOT manual)  I am trying to upload the GOT program using an old laptop with RS-232 port and have tried all baud rates on COM1 in the software. No other COM ports show any connection on the laptop, which is expected. I have even tried changing the GOT-type (although I figured it would be A870GOT-EL). The other options for GOT are A870GOT-TFT, STN/A810GOT or A85*GOT-STN,L. I have also tried to upload from memory and memory card, which are options, with no luck. I keep getting a connection failed message every time I try to upload. Any help will be appreciated. Thanks guys! 
  3. GOT 800 Upload Connection Failure

    The port I'm connecting to says RS-232C beneath it, if that helps any. @Veganic Maybe it is just the fact that I'm not using Windows 95? I'm not sure how we are going to install Windows 95 to try that though haha! I may just be starting from scratch for an upgrade (YAY!)   
  4. GOT 800 Upload Connection Failure

    @kaare_tI tried a RS-422 converter cable and still had no luck. I even tried all the different communication settings, but couldn't communicate. I'm not sure what I'm doing wrong.
  5. GOT 800 Upload Connection Failure

    Sorry for the delayed reply. I finally came around back to this issue. Below you will see the recommended cable AC30R2-9P found inside the SW3NIW-A8GOTP Operating Manual in the section describing how to connect to the GOT. I noticed that this is to send data to the GOT, but would it be the same to upload data from the GOT? I haven't done anything yet to figure out how to convert to RS422 though to see if that is my issue.    SW3NIW-A8GOTP Operating Manual (Software).pdf
  6. GOT 800 Upload Connection Failure

    I'll check the cable again or see if we have another one kicking around. I only mentioned that I was using the RS232 port off the laptop. I am plugged into the RS-422 port (I'm guessing) on the GOT. See the attached picture for where I am connecting to the GOT to ensure I am attempting to connect in the right spot. 
  7. QJ71E71-100 communication between PLC

    Nevermind, just found out that a Q is unable to communicate with the FX3U-ENET-ADP, but apparently it can communicate with the FX3U-ENET. I was given some code by Mitsubishi tech support to communicate via MC Protocol and will give that a try. 
  8. @Gambit We are also trying to communicate between a Q series PLC and an FX using MC Protocol. My question is, are we able to use the last function block you listed (...EthernetFX3QMC...) inside the Q series PLC program? We are hoping to capture (pull) data from multiple FX series PLCs using the Q as the master who reads the data. So is it possible to use that FB in the Q program to read data from the FX using MC Protocol?   
  9. QJ71E71-100 communication between PLC

    @kaare_t  I am trying to communicate via MC Protocol from a Q03UDECPU with QJ71E71-100 module - through ENET switch - to an FX3U-ENET-ADP attached to a FX3U PLC. The FX3U-ENET-ADP only allows TCP > MC Protocol communication as seen in my attached picture. This is the only reason I'm now trying to communicate via MC Protocol, whereas before I was able to communicate through fixed buffer from Q to Q PLC (using a S.JREAD instruction). How do I pull data to the Q from the FX3U ? Do I need a Mitsubishi MC Protocol Function Block to do this or can I still use Simple project > ladder logic instructions in GXWorks2? Using the settings you posted - Unpassive - how does the PLC know which destination IP address or port to go and receive the data from (the FX3U at 192.168.1.23 port 20512 in my case) ? Below are the FX3U settings I have set up to communicate through the FX3U-ENET-ADP:        
  10. Error Setting up QJ71MES96US

    The PLC and MES are faulted when trying to set it up. Any help would be appreciated. PLC Rack is as follows: Q03UDECPU (Slot 0), QJ71MES96US (Slot 1 & 2) and then QJ71E71-100 (Slot 3). Attached are photos of parameters, MES setup, and Error Message. I am not sure what I am doing wrong in setting up the MES module to match the PLC parameters. I imagine this is what is causing the error. Both the CPU and MES module are faulted with red blinking lights. I also was unable to change the Target CPU in the MES setting utility, even though I'm not sure I'm supposed to. I tried changing it to 2 (since the MES unit is the 2nd CPU) and when I change tabs, and go back, it is reverted back to 1, although still not sure this is the issue. I did "Write" the setting in the 'Online operation' tab, received a message saying the setting change was successful and then reset both the PLC and MES.   
  11. Error Setting up QJ71MES96US

    YAY! I got it to work with the QJ71E71-100 Ethernet card too now. Thanks Daniel for all your effort to help! 
  12. Error Setting up QJ71MES96US

    Thanks Daniel, I got it to work finally! The only thing I changed inside the MES CPU configurator settings was the Base Mode. I changed it from Auto to Detail, which I have no idea what that does. 
  13. Error Setting up QJ71MES96US

    I'll need to check on the link parameter error, but I doubt I still have that since I don't have the Ethernet card in the rack anymore. That would be great to have a multi-cpu configuration, but what do you mean change the 2nd CPU type? How do you specify the type of CPU?  I'm thinking it all has to do with setting up the MES module settings to match the CPU parameters, but I could be wrong.
  14. Error Setting up QJ71MES96US

    @collinsd70 - The above failed. I was successful in creating a program with just the PLC in the rack, but once I tried to add the MES module as a 2nd PLC, both the CPU and MES module faulted. I think I matched the parameters/settings, but it still won't work. The MES module takes up 2 slots in the rack, but I'm not sure how to specify that in the multiple CPU settings. 
  15. Error Setting up QJ71MES96US

    Thanks @collinsd70. I will try to run the rack with the bar essentials and gradually add modules like you said. That is great advice, thank you! When I get a chance I will upload the manual if I don't have much success in setting it all up. Thanks again. I will update later with my progress.
  16. Error Setting up QJ71MES96US

    Still no luck. Please Help! 
  17. Error Setting up QJ71MES96US

    I just noticed that I left a spare in Slot 1, assuming I needed to with the MES module taking up 2 slots physically. I will try moving the QJ71E71-100 module to Slot 1 in the PLC parameters and MES module settings to see what happens. I'll respond back if it is successful. 
  18. JP.Read QJ71E71-100 Channels

    Okay thanks. I wasn't sure about this, and wanted to confirm that I could try to step through or use a timer to talk to different stations through one channel. I didn't want to bog down one channel, but I know you're right that it is quite fast. Thank you for the response. 
  19. JP.Read QJ71E71-100 Channels

    I'm using a JP.Read Instruction and from my basic understanding I believe it communicates through a single channel. In the control data I need to specify word address of which channel to use. My question is, if I am trying to communicate with several Q03UDECPU PLCs (say 16 stations using the maximum 16 sockets of the QJ71E71-100 module) is it only possible to communicate simultaneously to 8 stations since it only has 8 channels? I'm trying to continuously read the data of 16 stations as fast as effectively possible, but not sure how to do that with only 8 channels to work with (I think the max channels is 8). 
  20. In a simple bench test, I am trying to communicate between two Q03UDECPU PLCs through a QJ71E71-100 module (both in Slot 0 on the racks) through a 3 foot Ethernet cable. I get an instruction error when I try to execute the GP.Read instruction. It doesn't give any indication why it fails, but the CPU faults out trying to execute this instruction. Any help would be appreciated.      If you want, I can attach both PLC programs. 
  21. Connect PC through QJ71E71-100

    I read through multiple previous posts on this topic, but still can't connect my laptop to a Q03UDECPU using GXWorks2 (Version  1.540N) through an Ethernet switch via QJ71E71-100 card. I can ping the ethernet card, but can't seem to connect at all. Here is my setup: Q03UDECPU with local QJ71E71-100 module (with I.P. address 192.168.1.10, Network 1 Station 1). The Q03UDECPU is CPU 1 in a multiple CPU setting with another EIP4CCPU module in the rack as well. TCP > MELSOFT CONNECTION ( x 2 , one for successfully connected GOT and one for my unsuccessful PC), and other TCP connection (For successfully connected MES module) PC I.P. address: 192.168.1.77 Subnet Mask: 255.255.255.0 Attached you will see all QJ71E17-100 settings and also connection properties with which I am trying to connect. What am I doing wrong?   
  22. Q to Q Enet Comm - GP.Read Instruction Error

    I believe I am using a crossover cable between the two QJ71E71-100 Ethernet modules, but maybe I need a switch in between (?) . My laptop PC is connected via USB to PLC1. I did discover my first mistake, as I had the network number wrong in my control data D2004. Now I don't get an instruction error, but now a Comm error which I need to look into. In a loopback test it appears that PLC1 is not able to communicate with PLC2.
  23. Connect PC through QJ71E71-100

    Oh! Okay, that makes a lot of sense. I was never sure, or never looked hard enough to figure that out (PC vs PLC side). THANKS A LOT !
  24. MES push or pull data?

    Wow! Thank you for the reply as it is all great information. I hadn't considered your last point regarding DRY, but that is very helpful in developing this! Speed isn't an issue as we are merely collecting a set of registers or different sets of registers for data collection purposes every couple hours on a given machine. It is a collection of data all at once. We may run into a scenario where we attempt to collect data on multiple machines at once, but we are more considered with reliability and ease of setup & future use. I think I decided we are going to pull data from each PLC via a master, once it is signaled to do so based on your last point about repetitive code change (DRY). I was also made aware that the MES module is limited in the number of devices it can connect to. I did not realize, nor do I quite understand what you mean by a limitation on sub PLC connections, but I'll cross that bridge when I get to it. Thanks! 
  25. MES push or pull data?

    Here is our setup, QJ71MES96US module in a PLC rack connected to an Ethernet switch. Also connected to this switch are several PLCs (Q03UDECPU) through an Ethernet QJ71E71-100 module with which we hope to collect data.  There are two different ideas floating around, one being that upon a trigger the MES pulls data from each PLC. So each PLC would need to be added as a device inside the MES workbench software. The second idea is that we place a CPU locally in the rack with the MES module and the MES only pulls data from the one PLC. In this second scenario each PLC, if possible, would push data through the Enet switch onto the one local PLC. I imagine this may be possible, but I'm not familiar with how. In another area of our plant this is the way we do it, but through a GOT, which I didn't want to do again. The reason it uses a GOT in that area to push data upon a trigger is because we are connecting to older PLC CPUs (A-series I think). My thought is that it would be easier to just pull data from all the several PLCs, even though I believe my manager and I.T. department are leaning to do it the other way, granted they don't know PLCs or PLC programming. We are all open to weighing our options though, so would anyone be able to chime in on advantages and disadvantages or even touch on simplicity to compare these two options?
