  1. Socket communication with Micro820

    Hi everyone ! I have a little project wich involves communication between two Micro820 controllers via TCP/IP. To do that, I started to work with TCP/IP socket. Within CCW (Connected Components Workbench), I tried to create a new socket instance using the instruction SOCKET_CREATE and set the socket address to 127.0.0.1:21. Basically, my computer through the FTP port. The problem was that it couldn't create a new socket instance (error variable is set to TRUE and status is set to 4, wich I don't know the meaning) because I didn't have a server-side application that listens to TCP/IP socket requests. That said, I found an open source application called SocketTest that listens for TCP/IP socket requests on a specified IP address and port. So, I started a listener on the following address : 127.0.0.1:21, but the error variable is still set to TRUE and status is still set to 4. So, my questions are : Is my IP address OK ? Is my port number OK ? What means the status code 4 ? Is SocketTest doing what I think it does ? Do I need to do something else before using the SOCKET_CREATE instruction ? Thank you in advance for your help !
  2. Can't connect to Micro820 controller via CCW

    Hi everybody, Recently, I started working on a project. I want to develop a program for a Micro820 controller (2080-LC20-20AWB) using CCW (Connected Components Workbench). I built a little motor circuit for testing purpose. However, after building the program and downloading it to the controller, I tried to connect to my controller via CCW, but I can't. When I click the button "Connect", CWW crashes OR a window saying : "The controller has unnacepted changes" appears and asks me if I want to "Download current project to the controller" (wich I already did) or "Upload the project in the controller to overwrite current project content" (wich is grayed out). When I choose to "Download current project to the controller", CCW starts downloading the resource, but fails. In the "Output" window, there's a line saying : "Download failed for Device:Micro820: An error occured while reading from GETACTIVERESOURCELIST.". The problem is that there's no documentation at all concerning this error. I even tried to reinstall CCW, but it didn't fix the problem. I joined some images so you guys can see what I'm talking about. Don't mind asking for more details !
  3. FR-DU04 (FR-A500) vs FR-DU04-1 (FR-V500). Programming unit differences. (A VSD question) What is the difference between these units? Why are they not interchangeable. (Other than the fact that the FR-DU04-1 is used for vector VSD applications, and the FR-DU04 is intended for standard induction motor applications. Is this a matter of firmware differences?
  4. Error 6706 Mitsubishi FX2N

    Hey guys, I'm really a newbie on PLC's, I'm working with a metal sheet folding machine. The past programmer gave me it's code, but I guess he gave me the wrong one. So, I uploaded the program with GX Developer 8 to a Mitsubishi FX2N-32MR PLC, all looked fine until I tried to run out the program. The error 6706 appeared up on step 3928 (blue rectangle). I read something about it already in other posts. But I'm not quite sure what to do. Can someone point me on the right direction? I attached an image where the problem thst showed up.  Thanks. 
  5. Dear Support Team, We have a problem in our AB PLC 5/60 Enhanced device(1785-L60B/E), it is a redundant AB PLC system  and controlling a Water RO plant. Another paralleled connected system is working fine. 1. Once power went down and power up, the PLC started showing "PROC" error- Steady RED. Loaded the program from EEPROM, the PLC "PROC" error is gone but the DH Channel A RED LED is started Flashing. 2. After loading the program, the program vanishes automatically even when there is a power, and again showing "PROC " Error - Steady RED. Changed new Battery. 3. Looking for the replacement processor,  found same series and part number but the Firmware and REV is different. Advise the selection of suitable replacement. 4. The PLC program is password locked. Any solutions or work around to solve the issue.    
  6. Hi all. Firstly, I am not a programmer, I just need advice. We have HMI's using NS-Runtime and we keep getting this message. Now, this is why I am contacting you all. This has happened over 20 times on 20 different HMI's which we have replaced over the last 3 years. We have been told by our software supplier that the com port is "on it's way out". There is NO WAY over 20 hmi's over that period will deveop com port faults. So my question guys, can someone give me a few tips on what to try before I change HMI's over ervery dang mponth please? I am really at the end of my tether here. We connect our HMI's to the Omron PLC's via a standard serial. If we change to another HMI the machine communicates after obviously a long period of downtime. Should we reset the plc? I will take ANY advise please guys.
  7. Hi everyone, recently we got a complain about UM password protection in the CP1L. So our user intended to apply password to a CP1L PLC which doesn't have battery installed. They were testing to turning off the PLC for about a week. In the 8th day, they turned it on again and tried to upload the program from the PLC. But after they input the password, and error shows up which indicates whether the password is wrong, or already inputted wrong 5 times in a row. Further checking shows that A99.12 memory was turned on which indicates that wrong password has been inputted 5 times. This was not the actual case since we make sure no one was using the PLC in those 7 days. A99.12 by its nature is not a non-retain memory. Is it possible that during Power On, the memory is unstable that it turned On by itself? I know it can be the case on some areas like DM / WR and also the RTC memory. And since A99.12 is a Read-Only memory, we cannot use P_First_Cycle to ensure it's turned Off as what we used to do with A500.12 (Inhibit Output). Currently I'm testing it by myself, for 3 days had left the PLC Powered Off. If anyone had inputs about this please advice. Thank you

  9. Trying to log into NA HMI, NA5-7U001B  Direct, using USB or Ethernet.  All attempts failed .. tho, it was easy to log into the NJ Controller, direct, with USB or Ethernet using the same PC. Then a window popped up.. saying the firmware needed updating in the HMI, and suggested launching the "update" from the same window... Then, after a few minutes.  a "update failed" was displayed on the window.. and the HMI screen changed to this: ..and the green LED went RED ... aaaaagh!   HMI no longer works... any idea why this happened, or the failure to log in happened.. or, what it will take to fix it? Please tell me it was something Omron did .... Thanks Much, Regards, ,Michael PS:  additional info..  I was using Sysmac Studio Version 1.1 .. because I could log in to the CPU (USB and Ethernet) and not the HMI.. I changed to another PC with Sysmac Studio Version 1.17 .. Now I was only able to log into the CPU with Ethernet.. USB login failed. .. and, so did any attempt to log in to the HMI (USB or Ethernet) It looks like if you use a new version of Sysmac.. better not have a device with  "old firmware" ..  I think it was the V1.17 that presented the window suggesting the Firmware Update ...  sigh!

  13. NB7W-TW00B Print Error 7300-FFFB

    Good day lads, we encountered an error on a NByW-TW00B HMI, showing "Print Error 7300-FFFB". Checked already on the manual, which mentioned this : "Driver & UI Printer Settings Disable" (V106 manual, Section 7-9). What's worse is that NB manual doesn't give any workaround for any printer error. The NB is not connected to any printer. The "Enable Print" tickbox is unselected (checked both in the program and in the System Setup Screen). Also there is no button/macro which triggers any print function. Any of you have encountered this? Any advice is appreciated. Thank you

    Im having some trouble with a PLC and looking for a some help. Whats happening is output number 3 is stuck on. I thought maybe it was just the PLC. I pulled the program tried it on a new PLC with no luck. I checked for faults and the handheld shows no major faults. The output that is stuck on is for a door, its telling it that the door is open. Any help would be great.
  15. Hi everyone, First time posting here, sorry if I screwed up any rules on this forum. I have a logic file that was created two years ago. I'm using RSLogix 5000 version 20.04. The customer has owned it for two years, and I just got the latest copy back from them to do a kit. So when I go to save my changes (offline), I get "Failed to save the project as 'filepath'. An unexpected CTree error occurred." Error 753-80042211. (see attached screenshot) I tried searching this error on google, with no results. I went to the help dialog box, which wasn't helpful. (See second attached screenshot) I can't think of anything else to do, my boss is gone until two weeks from now, the other guy in my department has less experience than me.   Can anyone think of a way to fix this? Otherwise I'm completely stuck. Don't think my boss will be happy with me getting nothing done for a week.   The help file says: Error saving the project to a different file An attempt to save the project to a different file failed. The error message you receive indicates one of the following conditions: Name is badly formed The name does not follow the IEC-1131 Name standard. Enter an IEC-1131 compliant name. >>> I tried the name "test" with no success Access denied If the file already exists, make sure that you have read/write privileges to it. >>> It is not set to read only or anything of that sort In use by another process The file is being edited by another process.

If you are saving to a network drive, make sure that you are still connected to it.
