Hi,
I want to use a third party gateway with RS Logix5000 PLC over Ethernet/IP. Third party gateway has proprietary interface on the other side for diff types of devices.
For this system I want to build a modular EDS file. First of all is it possible to have modular EDS file for third party devices with RS Logix5000.
Thanks.
Hi everyone. Good day!
I want to know what kind of ethernet cable configuration to use in order to connect remote ethernet adapters (1769-AENTR). What should i use, straight through or crossover.
Thanks!
Looking through the ladder logic on my program and came across an OTL instruction, and when I cross reference it, there's no OTU. Is this normal? It was my understanding any OTL instruction must have an OTU associated with it.
I hate to start a new topic on such an old processor but I forced to keep this thing working until I can upgrade it. We are having funny issues with outputs. At first they were on a PLC5/60. We suspected a bad processor so we changed to a PLC5/40 we had in our tool crib and the problem didn't go away. Some of our outputs in the ladder are being evaluated to true but not turning on. We can force the output on and it will come on and when we remove the force it will turn back off. I've never seen this problem before on any processor. All the logic leading up to the output is true but the output is not turning on and is there not green.
I've already checked all the obvious causes. The instruction is an OTE. The output is not duplicated somewhere else in the logic that is turning it off. The ladder file is being scanned. I replaced the output with a B3 bit and on the next line had the B3 bit turn on the ouput. The B3 output bit turned on but the output did not. This output is on a remote I/O rack and other outputs on that rack are working.
Any ideas would be greatly appreciated.
So I have been using Tag Groups for a while
But I have run into a problem that has me stumped
I am trying to get the .value of a tag group item and use it as part of a file path
Example
Creating a file name from a tag.value
Set MyTagGroup = Application.CreateTagGroup(Me.AreaName)
Dim Dfile As String
Dim NewFile As Tag
MyTagGroup.Add "Recipe\Recipe_FBK_Formulation"
MyTagGroup.Active = True
Set NewFile = MyTagGroup.Item("Recipe\Recipe_FBK_Formulation")
Dfile = "C:\Access_DB\" & NewFile.Value & ".txt" 'name of file
End Sub
Now the value of Tag Recipe\Recipe_FBK_Formulation is equal to "CF12GH" and will show that if I drop a string display object on the display
But when used as above, Instead of the value, it seems to be trying to use /::Recipe\Recipe_FBK_Formulation as the value not CF12GH
So what am I doing wrong
Hi , I have a new Panel view 300 , I need to change it communniation setting from DF1 to DH485, please kindly give me some advice, thanks.
i have a panelview 1500 and when i try to go to different screens on it it open for a second and then goes back to the main screen, any one know what would cause this? it was working fine and then just started doing it, ive tried resetting power and the screen itself nothing is working
Hello,
I am a new rslogix and visual basic user. I am trying to write a visual basic 6 (will upgrade later) program to communicate with a ladder logix program (rslogix 500/rslinx 2.57) to control a micrologix 1761 microcontroller. I want to build and control a start/stop switch for any output. Easy enough in rslogix. But what I want to do is create an HMI in visual basic and have it control the switch. I have loaded mscomm32 but what I don't seem to understand is how the visual basic program is going to communicate with the rslogix or rslinx. Do the button programs in visual basic need to show the bit storage places in rslogix. If so how is this set up? Can someone enlighten me? PS be easy on me as I am an old man and it takes me some time to understand.

I know that the most common programming languages are Ladder, Structured Text, and Function Block, but I'm curious how many forum members have experience with Sequential Function Charts? I just took some Rockwell training and asked the same question there, the answer I got was that SFC's are more common in Europe.
I've been playing around a bit with them, as I think they would be good for programming the Automatic Mode of a State machine. Thoughts? I'm curious for some Pros & Cons from other members?
Thanks!
Good afternoon fellow members,
I once again ask for your help to know if any of you have struggled with similar issues. For the past year and a half, Every 1-2 months we seem to be losing communication with one of our PLC's/racks. We have in the rack a 1756-EN2T card (revision 3.006) that will flash as if it is communicating and status OK (green LED), yet we will be unable to ping it and our operator interfaces go into error. We could also not open the web browser page of the EN2T card, nor connect to the PLC/rack through RSLogix5000. As this happened over the weekend, the local electrician was called and he tried cycling power to the rack and there was no change after it came back on (not sure how long he left power off to the rack though).
The problem seemed to be fixed after we told him to pull the EN2T card out of its slot and then re-insert it.
We verified the CIP cinnections for this card and it is around 98 to 101 CIP connections out of a max of 248, so not too high. the card's CPU usage is 24-29%, so no indication of problems there.
EN2T Card is set to auto-negociate, just like all the other cards we use at all of our plants.
Has anyone ever experienced a similar problem?
Thank you in advance for all your help and knowledge-sharing!
Good morning i want to know how i can recognize into the compactlogix 1769-L24 ER the micro 850 (2080-LC50-24QBB), because i want to communicate this two devices with MSG, i already i can see these two equipments into RSlinx but when i start Studio 5000 i don't know whick module i have to use it to recognize the micro 850, please help me
So I'm working on a project and I'm not sure what the best way to index a dial is. The indexer is a 3 position camco with one position prox. I have 3 stations, one the operator loads 3 items which are verified by prox sensors, the next torques two screws and the third offloads the final part on to a conveyor, or if the part failed position two skips the off load and returns the part to the operator. I need to verify all the parts are there before I index, and if the screw torque fails track the part back to the operator. I have never done an index like this so I am looking for ideas. Thanks for any thoughts.
I'm guessing there are going to be a lot of fans for using the PanelView HMI's with RSLogix PLC's, and I understand that. My question is whether it is the only real good choice?
Currently I've been using Maple Systems HMI's with all of my systems. It's only because it was the first that I was introduced to and became familiar with the software. As busy as things can get, I've just stuck with using them instead of learn something new. However, my eyes have recently been opened to some best practices in programming in RSLogix, such as Alias Tags, and UDT's, etc. Maple Systems doesn't handle all of this stuff well, some not at all.
So are there different 3rd party HMI's that are easier/better than Maple Systems? Is the PanelView worth the price from a plug and play standpoint? Or is it even plug and play? If PanelView is the best, what are my software requirements to program them?
Is there any way to open a existing file that is saved in a protected format that is not the original file in the HMI?
Hello All,
I have been researching KEPServerEX and Rockwell's Factory Talk Transaction manager. I would appreciate this forums opinion/recommendations. I think the going rate for these packages is about $2,600.
Typically my applications require a very small amount of SQL Database interaction.
A typical application would be a small system using a compact logix such as an (5069-L306ER).
I could have less than 100 tags holding string data I would like to write to a table in the SQL database.
I have some basic part configuration data I might like to read into the PLC from a database.
Do either of these software packages have the ability to trigger queries or stored procedures? (probably don’t need that, but I am curious)
Please let me know what your experience has been.
Thanks
