You should pay for the support contract to be able to contiune to receive updates. The Master KEY can be retrived by running EVMOVE.exe and moving the key to a blank floppy. EVMOVE.exe can be found in the Rockwell Software folder. After you receive the CD's from AB and install RSLogix, find the EVMOVE.exe and move the Master Key from the blank floppy that you saved your key to. I hope this helps. swimmy67 -

Chris, I tried downloading the Communication Manual from home and I was not able to open it even with Acrobat 6. I reuploaded the Communication Maunal by editing the Upload. When I tried downloading t he file again, it opened and downloaded fine. I hope everything else is OK. Thanks, swimmy67 -
Hello all, Was everyone that downloaded the FX3U manuals that I uploaded able to open and view the PDF files? I have heard that some people that downloaded the files were not able to open them. The problem that I had was with Acrobat 7. I had to uninstall Acrobat 7 and reinstall Acrobat 6. I was able to open and view all of the files with Acrobat 6. Please let me know if I will need to repost or if they are OK. Thanks, swimmy67 -
It is not a good idea to put multiple instances of the same OTE instruction in different Subroutines. By putting the same OTE instruction in different subroutines, there could be a possibility of the OTE being enabled when it should be disabled. The scan of the program will put the inputs and outputs at their last read state. If one subroutine is calling for the OTE to be on and it is scanned first, and another subroutine is calling for the OTE to be off and it is scanned last, the last subroutine to be scanned will be the state of the OTE instruction. Again, it is not a very good idea to put more than one of the same OTE instruction in separate subroutines. -
FX3U
in Mitsubishi
I posted all of the information that I receoved from Mitsubishi for the FX3U PLC. I included all of the manuals and the accessory manuals. They are located in the Download section. Thanks, swimmy67 -
After modifying an existing program to run on the FX3U PLC, I find that the instructions for communicating with Mitsubishi inverters is similar to the FX2N-ROM-E1 module with the communication instructions built in. The FX3U has two channels to choose. I have channel one set to the FX3U-USB-bd board. The FX3U-485-ADP module is set at channel two. Channel zero is the peogramming port which I will attach a GOT 1000 touch screen. I modified the program and downloaded with the USB cable supplied with the USB-BD board. Much faster than the SC09 serial cable. Online monitoring is much faster also. As is the online edits. This program has not been tested yet so at this time I aill not post. The program communicates with 3 FR-E540-0.4K-NA inverters. Has a PID function to control the Heat Exchanger via Analog output module FX2N-4DA. I have a 4 RTD input card, FX3U-4AD-PT-ADP to sense Process temp, Output temp, Over Temp, and Heat Exchanger internal temp. I should be testing the program with in the next few weeks, so I will post the finished program for review. Thanks All, Kari Swimrlar -
Chris, I have posted all of the FX3U manuals that I received from Mitsubishi today. For the programming, there are 4 separate manuals. Programming Basic instructions, Communication programming manual, Analog Programming manual, and Positioning Programming manual. In addition, I posted all of the additional hardware manuals that I received. I received the FX3U PLC, USB module, and FX3U-4AD-PT-ADP input card. With the USB interface, the programming is fast. I created a temporary program to see how the RTD module would function. I will post the price list for Mitsubishi Electric products tomorrow. I will try and share all of the information that I receive for the FX3U PLC. Thanks, Kari Swimelar -
Hello All, I am receiving an FX3U plc and I was wondering if someone has any programming samples for the PID function (FNC 88). I read through the manuals that I received from Mitsubishi. I was not able to find much information on their Web site about the new processor. There are some improvements with the FX3U. 1) Built in communications function for communicating with the Mits inverters. 2) Improved PID function with additional parameters added. 3) Can connect modules to the Left side of the PLC for faster communication speed. 4) Supports USB programming. I am looking forward to receiving the PLC today. I only hope that the PID function will perform better. I use the PID to control a Heat Exchanger for heating cooking oil for an industrial Fryer. When I have a working program, I will post it for review. Thanks, swimmy67 -

waynes, Thanks for the responce. Concerinig the sampeling rate, what would be a good time? Is 2sec too great of a sampeling time? Looking through the program, I am setting d51 to H33. during the run process. For autotune I am loading H30 into d51. I have read and reread the manual for the FX2N PLC. In section 10, there is a more detailed discription of the PID loop with example code. Still, when I try using the sample code, I can not get the PID to function correctly. The code that I posted is what the machine will run. I guess I need some more experience with the Mitsu PID function. This is my first time using the Mitsu FX2N PLC and the PID Function. I normally program with Allen Bradley SLC and ML PLC's. Thanks for your help in this matter. Kari -
Hello all, It seems that the file did not get attached. Here is ths program. Thanks, Kari FX2N_PID.zip -
Does anyone have experience with the PID function in a FX2N plc. I am using GX Developer Ver 7.11. Attached is the program that I am using. I can not control the PID from the beginning. The only time that I enable the PID function is when the process temp is within 5 deg of the setpoint temp. When within this range, I load a max and min value into the output min/max variable so the output will function say between 15% to 50%. At any other time the output is 100% if more than 5 deg below setpoint, or 0% if more than 5 deg above setpoint. I am trying to control a heat exchanger. I am using a FX2N-4DA output card with the analog signal set to 4-20ma. A Honeywell Modutrol actuator to open or close the damper. Any help in this manner would be greatly appreciated. Thanks, Kari Swimelar Electrical Engineer KJC Electric Inc.
