  1. Hello everyone: I´m gettin an error when I go online in a Quantum Modicon 140 CPU 424 0x controller. When Concept compare the offline file with the PLC I receive the message: "Controller´s configuration not equal to configuration database (Miscompare at word 299)" and I have a "NOT EQUAL" Status. I solve this temporary uploading only the Configuration from the PLC but when I save the program go offline and try to go online again I got the same message. Any clues about this? Maybe the solution is downloading again the backup but I would like to known what is happening here before downloading the program again. Regards Chalpa

  3. WinMMI complete Manual

    Hello: I`m looking for a complete manual for the WinMMI Software (I`m attaching a file with the About.. screen). This is a very old software from where we need to export some data but the OEM only provided a partial manual (only the chapters used in the project) and now we need to use another control of functions not used before. Any one had hear about this? Regards Chalpa
  4. Hello: Some time ago I developed a Visual Basic 6 application to send and receive data over an Ethernet network from between a PC and special equipment using standar TCP/IP text telegrams. Actually the customer wants to replace this equipment for an array of Siemens S7 PLCs, they want me to modify this Visual Basic application to send this data to the S7 Plcs over a Profibus network. I need to know what I have to add to my Visual Basic application in order to get the communication between the old PC and the new S7 Plcs. There's a library or software that I can purchase so I don't have to change the Ethernet card? I need to purchase a Profibus Card to get this working? Thanks in advance for your help. Regards. Chalpa

    Hello: Anyone has the pinout for the serial cable to connect a PC with a Mitsubishi series Q PLC? Regards
  6. QJ71C24N Configuration

    I just rearrange the PLC modules exactly like it is explained in the Manual SH_NA_080006-M Appendix 9 and any time I turn on the input of the Z.REMFR instruction the PLC faults. I reproduce the system and example exactly like in the manual. Usually this always work, go back to the basics and them start from there but now it is not working. :(
  7. QJ71C24N Configuration

    yes, I have it, I'm trying to use the z.remfr instruction to get the data from the module but any time i power the instruction the plc goes to fault mode. The Module is installed in the four slot and I'm using: -----[ Z.REMFR "J1" K1 K1 H0 H0A6 D0 K1 M400]-- I'm guessing that it is something about the module position but i can not get it.
  8. QJ71C24N Configuration

    Hi: The switchs settings are ok, I'm actually receiving data but the PLC get it from the module memory after receiving a certain number of frames an not after the ETX character. I guess it is in character count mode and I looking how to change this setting without using the GX Configurator Thanks for your help
  9. QJ71C24N Configuration

    Hello: I'm trying to receive data using a QJ71C24N module and a Q00J CPU. How can I change the communications parameters without using the GX Configurator-SC? I read the manual and it says that I can configure the Baud Rate, and other ASCII parameters changing the switch settings in the module, but I don't known how to set the operation mode on "reception via receive complete code" or "reception via received data count". My application needs that I check the STX and ETX on each frame in order to known when the communication Start and Finish. I need the GX Configurator to check/change this parameters? How much it cost? It is an alternative method for it? Regards
  10. Profinet Ring Switch

    I just find this device, The SCALANCE X204IRT from Siemens. Do you think it can fullfill the above request? Regards
  11. Profinet Ring Switch

    Hello everyone: I was wondering if could exists a device that can connect on a Profinet ring some devices sending control, programming and data signals over the same physical network. I´m attaching a picture showing the concept. Our customer wants to install only a ring on all the line and receive control signals and data from the devices as to change the program parameter connecting to them over ethernet. Thanks in advance for your help
  12. Connecting with a CP443-1IT

    Hello: I´m making a Visual Basic interface to sent info to a CPU416-2DP using a CP443-1IT module. In order to connect to the module I need a IP Adress and a port number. The people in charge of the PLC part can give me the IP Adress but they don´t have any idea what the port number is. Can someone help me with this? What is the port numbers that I could use to connect? Thanks in advance for your help.
  13. Indirect addresing in FX2 PLC

    Hi: I´m actually developing an application where i receive infor from a server using a RS232 serial port. Initially I only have to store the info for 10-15 units in the production line but now the customer wants that I store the info for 180-200 units in the PLC. I think the memory is not a problem (each units uses 8 register of info) but I need to known if it is possible to use indirect addresing to store and retrieve this info from the FX2 Memory so I don´t have to program each option separately using a Counter and a BMOV instruction. Is it this possible? Regards
  14. Hi: I need to known if it is possible to have two Interface Module FX2N-232IF conected in a FX2 PLC. I need to receive data from a serial device and compare it to the reading from a barcode scanner. I need to to shown both data in a display (I´m thinking to use a Control and Display Panel FX-10DM-E). Is it possible to do this? Thanks in andvance for your help.
