    It must work..there must be error in cable wiring. coz I had already used it...and it works simply as u connect wires and switch the powe on.
  4. FX2N PLC AND DRIVE COMMUNICATION (RS484) PROBLEM

    ok..u got it correct. here frequency write is going ok. and for receiving completion confirmation, logic is like either m8123 or a timer whichever is earlier will move to next drive. this i have done because there were 16 drives and if few among all are on and others are off then the m8123 from drives which are off will not be recieved and sequence wont go further. so i have taken one timer also , which in case of particular drive off, will move to next sequence after some time.

    yes exactly...!!! what veganic said.!!!! i vl just simplify it... the no. of station occupied u set multiplied by 4 , devices u can send and receive. if u set it to 4 u can exchange 16 devices.

    Hi, here is the link for the FX 2N 16 CCLM http://download.mitsubishi-automation.com/...submit=View+now and for FX2N 32CCL is http://download.mitsubishi-automation.com/...submit=View+now I ve did two projects with CC LINK and FX 3U. only the diff. is I had two cpu's and u have 3. That is of no matter. and the programming of this is also not a big deal. U just go through the both manuals thoroughly. The programming is simply with TO and FROM instruction. With the FX2N 16 CCLM - that is master block u need to configure the basic using TO and FROM instruction. and in FX2N 32 CCL - that is slave, only read the buffer memory alloacted for data exchange for particular station no. No configuration program required for 32 CCL. See in master block there is particular memory area allocated for each no. of connected station.u just need to write in those buffer memory and read at slave buffer correspondig to it. I have attached here excel sheets . It vl be very useful to u. and also in excel sheet there memory mapping of two plcs is prepared. from that ur half of the logic vl be cleared ... half is the game of reading manual. And yeah there is also external switch setting of master block as well as slave.That is very simple. In manual u vl easily find it out. Best Of Luck.
  7. FX2N PLC AND DRIVE COMMUNICATION (RS484) PROBLEM

    Drives are D700 mitsubishi. and none of them are giving this error.
  8. FX2N PLC AND DRIVE COMMUNICATION (RS484) PROBLEM

    First of all thanks for reply. The problem is not fixed with particular drives. It occurs radomly. and Not only plc also with the drives on HMI. HMI drive communication set up is as below: From RS 232 port a 232 to 485 converter is taken and from 485 side there is connected all 8 drives. so problem is like it stops communicating after certain time. From the indicatros on converter I observed no sending and receving was occuring. and again when I downloaded the same HMI program again it started communicating. This problem happened thrice and stil persisting.This is regarding drives on HMI. Now with drives on plc same problem is there. And program I have made is the same like u suggested. first i communicated one drive , response came and then started for another drive. Even I have checked all drives individually. They are communicating perfectly. As they put together , then starts malfuctioning. And ya, the time out parameters are already selected so , as they dont come in picture. The prog has been already checked no. of times , even at office also I set the same set up as at the site and put under observation but here no problem was detected. Actually my confusion is the below mentioned point: 1. It should not communicate even once if there is problem in program, where as situation is like it runs properly for one or one and half day. The problem starts afterwards.
  9. HELLO FRIENDS AND MASTERS, I M CARRYING OUT A PROJECT WITH 'FX2N' PLC. THERE ARE 16 DRIVES ON PROJECT. ALL ARE INITIALLY ON RS485 COMMUNICATION INITIALLY THROUGH 'FX2N 485 BD' . THE PROBLEM IS THAT AFTER CERTAIN TIME OF RUNNING PROPERLY THE DRIVES PUT UP COMMUNICATION. THE COMMUNICATION BEHAVIOUR BECOMES UNCERTAIN. AND THIS TIME DURATION IS IN BETWEEN 1 TO 1 & 1/2 DAY. IN STARTING IT COMMUNICATES PROPERLY. ALL DRIVES TAKING I/P FREQUENCY AND READING O/P FREQUENCY PROPERLY. PROBLEM STARTS AFTER ONE OR ONE AND HALF DAY. AFTERWARDS I CHANGED THE SCHEME , I SEPARATED DRIVES. TOOK 8 DRIVES ON PLC AND OTHER 8 DRIVES ON HMI (DUAL DRIVER). INITIALLY IT WORKED, BUT AFTER SOME TIME FEW DRIVES STOPPED READING FREQUENCY. THEY WERE TAKING I/P FREQUENCY PROPERLY. NOW HERE WHERE I CAN NOT LOCATE WHERE THE PROBLEM IS. AND THE REMEDIES WHICH I HAVE ALREADY IMPLEMENTED. ALL OF THE COMMUNICATION CABLES CHECKED AND REPLACED FAULTY ONES. CHECKED ALL DRIVES INDIVIDUALLY FOR COMMUNICATION. (WORKING PROPERLY) CHECKED PROGRAM THOROUGHLY, AND EVEN ARRANGED A SET UP AT OFFICE TO CHECK IT THE PROGRAM IS OK. SO PLZ HELP ME LOCATE PROBLEM.
  10. FX1n error light

    YOU DO ONE THING. CLEAR THE PLC MEMORY ONCE. AND MAKE ONE FRESH SAMPLE PROG. AND THEN CHECK WHETHER THAT ERROR IS GONE OR NOT? AND CAN U TELL ME THE PERIPHERAL DETAILS U USED WITH PLC?
