    Sorry Which type of servo motor ? Which type of connection are you using ? npn or pnp Are you using an interface/pulse converter/other device/... between plc outputs and your servo motor ? Some times i found the same problem but caused by wrong connections or differences in pulse logic between servo motor and plc. Bye Max

    Jim Each of us has different opinion about the plc programming tool. This depends of the different expereances of job that one has. I know old Beijer prog. tools and i think it's very good. Also i have been use Gx products for many years (actually i use Gx8.12), and i know merits and defects like all the other plc prog. tools of competitors. The Mitsubishi is continually developing the product so they will have to go out a lot of new versions. For me GX it's a good product. Bye You are in Scotland and i'm in Italy on vacation at the moment but i do not have a lot of time to vent, rant & rave but it's not important. Max

    I think you need FX2N-CNV-IF. It's an adapter for communication between new FX plc with digital and special module of old FX series. You have to install on the right of your plc configuration. bye Max

    Did you try to set different cpu type on Gx developer? For example, try to create a new project with A1S cpu and try to connect with M0J2. Some times is possible to connect with particular cpu model using a general cpu on Gx/Medoc settings. Of course if you succesfully connect by changing cpu settings, you cannot access to the full addessing map of the original plc. ... and asking to LG for the right software? bye Max

    Or ask to your customer to install Q02cpu with the possibility to create more files. Actually this function is available only with high speed Qcpu models. Howevere i think in the future Mitsubishi will change all the base Qcpu model with new firmware so to use multiple files and also memory card. Remember now basic models Qcpu have only 8ksteps memory. My be also the possibility to use FCALL instruction and [CALL Px S1..Sn] where you trnsmit different arguments to your Call subroutine, but i'm not sure this will help you. bye Max

    Did you check the target memory on plc with GX developer? Where you trying to find project? on program memory, standard ram, standard rom, memory card ? When you turn the switch to run position the run led indicator is on or off? Are you sure you have selected all the program area (main+parameters) ? very strange problem you have, retry again with a new empty project created on your GX and read from plc. bye Max

    I'm not sure to anderstund your problem. Probabily your Gx is configured as online-write mode, or automatic plc writing after convert a ladder program. Try to check in Tools-Options- WriteConversionWritingBehavior and set 'don't write to plc'. bye Max

    Does anyone know GX Explorer ? As i know is a software for remote plc programming. Is necessary to install particular card on plc rack, such web server module ? or normally it can be used with cpu direct connection or C24 ? Max

    Also in Mitsu plc you don't need everytime to configure I/O modules. My configuration is an example how you have to use your input/out address if you install the I/O modules from slot 0 to slot 7 like your example. With GX developer or Medoc you can write immediately the plc program after install the i/o modules. If you have 16 out module on slot 0 the address will be Y00-Y0F. On slot 3 to slot 6 you have 16 point modules and on slot 7 you have 32point module, so the address will be like my configuration. On Mitsu An/QnA/Q series modular plcs all the i/o address are in exadecimal, except on FX compact plc. Probabily the message you have after plc powering up is caused by plc program memory empty. Try to write a program with end instruction, do reset of cpu by key and it should clear the error. Hope everything was clear bye Max

    a3a cpu with 3 units ax41 , 2 units ay60, 2 units ay40, 1 unit ay13 The i/o assignement should be like this: Slot I/O number 0 = AX41 = 32input module = X00--X1F Slot I/O number 1 = AX41 = 32input module = X20--X3F Slot I/O number 2 = AX41 = 32input module = X40--X5F Slot I/O number 3 = AY60 = 16out module = Y60--Y6F Slot I/O number 4 = AY60 = 16out module = Y70--Y7F Slot I/O number 5 = AY40 = 16out module = Y80--Y8F Slot I/O number 6 = AY40 = 16out module = Y90--Y9F Slot I/O number 7 = AY13 = 32out module = YA0--YBF Bye Max

    Does anyone have expereance with Q6TEL module for modem connection? Is it available only in Japan or also in Europe? Thanks Max

    I need to emulate old A6GPP with my notebook. Anybody has the SW4IVD-GPPAE software package ? With this package is possible to emulate the cpm based GPP prog.units. Best regards Max

    I'm not sure but i think QJ71C24/N is not compatible with Modbus protocol. Only the old AnS serie series have a C24-S2 Modbus protocol compatible (slave module). May be possible in the future Mitsubishi will sell a new model of QJ71C24 bye Max

    Probaily i did not understund the discussion but.. If you use String comparison instruction with index register ? like: LD$ D0Z1 D100Z1 On D0,D1,...n you receive the input data On D100,D101,..n you have the ascii converted constants (i.e. 'RUN') Then on the top and on bottom you create a FOR-NEXT loop just to increment Z1 nidex. This is for crate an ASCII table block comparing. bye Max

    I need to communicate with modem using QJ71C24 just for plc program debugging. The configuration is: (my pc)-(modem)-----------(modem)-(QJ71C24/N)(QnHcpu) Normal analog phone line, no isdn First expereances on modem communication with Q cpu. Does anyone have suggestions for settings or procedure for a god communication? Is necessary to set the software switches on Gx parameters about QJ71C24 card? Best way is to use my pc internal modem or external device ? I tryed some times but start communication was not so easy. A lot of times i found an error report from Gx about 'remote password checking' but i'm sure i do not use password on plc. suggestions will be appreciated bye Max

    Take a look on this co-processor module of Mitsubishi Electric. Dedicated also for hydraulic applications. It use two slot on plc rack. I know some blow molding applications using servo valve control with feedback devices controlled by these modules bye Max SPAC_module.zip

    Hi Which type of LG plc ? However i remember some types of LG plcs were similar to Mitsubishi plc, and also the programming port. I suggest to contact Mitsubishi service or check in Internet, or LG automation site, or Daewoo Korean site. bye Max
