    While connected and online with the PLC, open the online blocks folder (select the Blocks folder of the project and click on the "online" button in the toolbar). Make sure OB121 is present in the processor, not just in the project. You can also select the blocks folder in the project tree and do an online/offline compare. It will tell you if OB121 is missing online.

    Note: OB121 does not fix the actual root problem. You need to find the actual issue and correct it. All the presence of OB121 will do is allow the PLC to keep running, which may NOT be the best and safest outcome in your situation.

    Yes I've seen OB121 on the processor when I'm online, the machine still doesn't run. 
    I'm just wondering if the processor or any modules were damaged in shipping. 
    Seimen's help isn't very helpful since the only two causes that are listed are a defective module or no signal module is assigned to address

    I really want to know what " Global DB, word access, Access address:    262 " is referring to, what does access address 262 even mean? 

    I was having some communication issues before, but that was resolved every module is showing ok when I'm online except the processor.

    Hi Rompot.

    It looks like your PLC has crashed because of a programming error, to prevent the PLC going to stop mode- you need to insert OB121 (this is the called OB on the rising edge of a programming error).

    Then you will have a system error- but PLC is able to run as normal.

    The most recent error indicates an area length error when reading/ writing to DB262. This could be because of a pointer or something changing during runtime. In your diagnostic buffer you should be able to navigate to the problem with the button 'go to', hope this helps.

    Insert it where? 

     


  3. Hi I'm a bit new to Siemens, we;re an Allen Bradley plant...until now. we just got a brand new used press and it has a seimens controller on it. The press doesn't seem to have any manual functions so I as asked to move the cylinder, but I can't until I clear this fault. it won't do anything. 

    I'm told I'm working with an older processor, s7 300?I don't really know seimens that well. 

    I saved the diagnostics buffer as a text file and pasted it below. in case that helps solve my problem. I'm thinking it's just having trouble communicating with remote IO, but I'm not sure. I might be trying to communicate to a robot that used to be there that no longer is.

  4. I have an old PanelView 1000 catalog number 2711-K10G1 that needs to be replaced, I don't want to replace it with another panel view 1000, I want to get a panelview plus, the problem is that the Panelview is connected to a PLC-5 and it's connected by DH+. The only thing I can think of is to use an 1761-NET-ENI to connect the PLC-5 to ethernet/IP...but even the ENIs are discontinued by Allen Bradley. Are there any panel views that have data highway? 


  5. Hi, I'm kind of a newbie at this, but we just replaced a panelview 1200 on a line. But I need to download the program to it. since I couldn't find the old file on our companies computers my thoughts were to upload the panel view program from one that is already working and then transfer it to the brand new used panelveiw that we replaced the old one with, but I haven't had luck. I keep getting a "no response from PanelView terminal" I tried using Panelbuild1200 in dosbox and on windows prompt in XP, but still no luck. 

    The solution from Rockwell's site is the following. 
    "

    This error message is normally seen if no cable is connected between the computer and the PanelView terminal

    Check cabling. Check comm port settings on the computer in the PanelView 1200 software and the PanelView terminal.

    Verify that the com port is available.

    If faster style computers (having 386, 486, 586 processors) are being used, this message may appear. It could be the case that the high speed processor is over running data at the comm port. To minimize this possibility, reduce the baud rate and try downloading again.

    Ensure that the Panelview terminal has the UPLOAD/DOWNLOAD screen displayed before attempting to download via the RS-232 port.
