  1. GOT2000 to SLC 500

    I am trying to connect GOT2000 to Allen Bradley SLC 5/03. I am following instructions in the GOT2000 Series Connection Manual for AB and at the same time I found in other forum a sample setup (attached image) and still connection is unsuccessful. Do you have any other guidelines that I might missed in my setup? Thanks in advance..    
  2. Stacker Crane Controller for AS/RS

    I need some inputs on a project I am working on, usually what I see in stacker crane plc based controller is Siemens PLC  using Siemens VFD for the lift  and travel motors. Can we do this in Mitsubishi Setup? Maybe you have experience with this, kindly share it.. Thanks!
  3. Stacker Crane Controller for AS/RS

    Thank you for sharing Gambit. For PLC I have tried browsing Mitsubishi Website but their reference is using Servo System, but what I see often in this application is using VFD using distance measurement device either using barcode or laser.  I also read some literature and found this trajectory control for VFD both for the Travel ( X-Axis) and Lifting ( Y-Axis) for the control of speed, acceleration/deceleration vs time with respect to the starting point to target location and I am still trying to figure out how to translate it into Mitsubishi PLC, maybe you have advanced explanation on this? Thanks..
  4. FIxed Buffer Communication

    Hi!! I am confused right now with the packet structure in sending data to an external device (Markem printer). I need to send this data (attached file) to the printer to update variable data to be printed. I am planning to use Fixed Buffer with no procedure. Do I simply use the instruction ZP.BUFSND? given that I have successfully opened the port for the target device (using ZP.OPEN instruction)? I need your expert advise.
  5. FIxed Buffer Communication

    I am liitle bit familiar with structured ladder. If you have example, please share then I can work it out.
  6. FIxed Buffer Communication

    Simple ladder only.
  7. FIxed Buffer Communication

    I am using GX works 2.
  8. FIxed Buffer Communication

    In addition to this, 2 samples of message format that is sent but I can not get how he arrived at the "Data Checksum" part. Printer Data Format.pdf
  9. FIxed Buffer Communication

    Sorry, here is the file.. Checksum Calculation.pdf
  10. FIxed Buffer Communication

    I will try to look for another Hub. But I am suspecting part of my message to the printer "Data Checksum", maybe you could help me translate it into ladder. I attached file including Packet structure and Header Checksum. I am confused on the Data Checksum calculation part.
  11. Maybe somebody has already done communicating this two devices (Cognex<->QJ71E71-100) already? I attached my setup on Cognex Dataman Setup Tool, please share your experience on this. Thanks!
  12. FIxed Buffer Communication

    Can I use CONTEC-Mitsubishi NZ2EHG-T8 as hub for this matter? NZ2EHG_T8.pdf
  13. Has anybody have this connection before? I am trying to convert the F940 GOT into GT1030, the big size of the F940 is not needed a smaller one is good. It is a little bit rush, I needed the pin configuration because distributor for the GT01-C30R4-25P will take 4 weeks to deliver. Can't make it to the deadline.
  14. FIxed Buffer Communication

    Is there any software that I can use to check what I am sending to the Printer? Like simultaneous monitoring?
  15. Cognex Dataman And QJ71E71-100 Communication

    I just got the communication running. Maybe the problem only was there is no enough power to run the Cognex Communication with Mitsubishi PLC. All settings I made the first time I tried to test communication failed and then I tried to have another separate DC power supply and I used the same settings and all were good.. I am glad COGNEX and Mitsubishi has partnership already, I used MC Protocol.. Thanks for your help!!!
  16. FIxed Buffer Communication

    I just testes communication through fixed buffer.. First, I used open port instruction and it went out successfully. And then I tried to send full message to Printer, the first message I got a negative acknowledge (nAK) response, does this mean I am communicating already with printer but wrong message format only?
  17. FIxed Buffer Communication

    I am using GX works 2 in ladder. I am more convenient in this way.
  18. MC Protocol Communication Function Blocks

    Hello!! I have to make Mitsubishi PLC as gateway for three devices wherein data will come from a server. Server and two of the devices will use MC protocol and the other devices is generic communication. The agreed protocol is TCP/IP. I have FB for fixed buffer communication already to communicate it with the device with generic protocol. However, the MC protocol I dont have FB for it. Maybe somebody can share it with me please. I am going to use Q00UJCPU and QJ71E71-100 and Switch/Hub. Thanks guys!!
  19. MC Protocol Communication Function Blocks

    I got the FBs already.. Thanks for your help!!
  20. Good day! I am working on a conversion of A3NCPU to Q06UDHCPU. I am having some problem with the microcomputer program conversion. It is my first time to encounter this type of program. Please kindly share your ideas. These are the instructions used a couple of times in the program. MOV H3C7 D9090 SUB K32 SUB K26 MOV H3C0 D9090 SUB K5 MOV H3C1 D9090 SUB K17 MOV H3C2 SUB K20 MOV H3C5 D9090 SUB K8 MOV H0CC D9090 SUB K59 MOV H3E4 D9090 SUB K68 MOV H3E4 SUB K65 I am trying to look at some manual and what I understand is it is intended to call a microcomputer program. This is the part where I am lost. Please help. By the way 1st slot is AD71, 2nd slot AD51 and the rest is I/O. Thanks!!
  21. Motion Controller

    I am working on a conversion of mechanical horizontal packaging equipment into servo controlled using Q172DCPU and MR J3 series servos. I am having trouble in making the cam data for the end sealer part which has a mechanical eccentric slow down. Maybe somebody here already tried converting it or maybe built a new machine using servo for the end sealing. Please share if you have some idea or some formula/equation that I can refer to in making the Cam data?? Thanks!!
  22. Mitsubishi Ethernet Connection to PC

    Hi I would like to ask if any one has ever tried connecting to PC based software using Mitsubishi Ethernet QJ71E71-100 module. The project is to exchange barcode data, send/receive this data between Mitsubishi PLC and PC based software.I tried to read some manuals related to Mitsubishi QJ71E71-100 and I am confused on choosing between MC Protocol, MELSOFT Connection and Socket Communication. as for the MC Protocol you need to input Host Station Port no. while for Socket Communication need to input Host Station Port no., Destination IP Address and Destination Port no. For now, the PC based software developer is asking me what protocol to use and as of now I couldn't give him the protocol. Please give me some ideas or maybe tutorials on this matter. Also, for the port no., what is the dedicated port no. for each protocol? Thanks!
  23. Mitsubishi Ethernet Connection to PC

    Thanks kaare_t for your quick response. If ever we agreed to use MC Protocol, PC developer can directly look into or move data to D registers or R registers? And I just look into the parameter setup for Ethernet Network using QJ71E71-100 , and comparing to the setup for CPUs with built-in ethernet they are not the same. For Ethernet Network, unpassive selection under open system and its equivalent on built-in ethernet cpu is MC Protocol?Am I right? And also, under Ethernet Network parameter Active and Fullpassive it seems there is no difference?
  24. CC link over Modbus

    Hi! I am trying to look for difference between cc link and modbus. As I understand, by principle they are almost the same and I could not define the advantages and disadvantages. You could give me some more detailed difference between the two. One client is asking me which interface is to use, CC link or Modbus? Since the connected device is open for both communication. Thanks!!
  25. AnS motion cpu

    I tried MT Developer but can not open for A171SHCPU only for Q series motion CPU. Maybe you can give me guidance in converting the program. Thanks!
