Technical support / Difficulty Troubleshooting Break Points
« Last post by suhelens on December 21, 2023, 02:30:55 AM »
Hi!

I have trouble debugging a breakpoint. I am trying to send to my machine via WRITEMODBUS function. Here is my code

DM[11] = 32808
DM[12] = 6399  //This is where the breakpoint occurs
DM[13] = 36647
DM[14] = 0
DM[15] = 0
DM[16] = 0
DM[17] = 0
SETSYSTEM 6,4
WRITEMB2 12,1,0,DM[11],7

What are some things to look out for at this breakpoint?

How do you count distance with a photo eye?  Photo eye typically is triggered when a part comes into front of it and block the light path into the photo eye (either transmissive or reflective). 

Once you get the reading to output the measured data to a display is very easy, especially with a PLC that has built-in display such as the Wx100 or FMD or FX PLC with a LCD420 display.

Need help making a program that will count with a photo eye. It needs to output the feet measured to a display and have a reset button. Anyone care to help? Tried a couple things but couldn't get it to work yet.

To monitor the micro-switch for changes from on to off using an interrupt (INTRDEF) and Custom Function, set up a second interrupt routine for this specific condition. This way, you can respond to both state changes of the micro-switch in real-time.

It's great to see your insights into optimizing this circuit. Using a custom function and sampling the input with a refresh and DELAY statement does sound like a viable alternative. It's interesting how this approach can reduce the ladder logic complexity but might require more code within the custom function.
You've also pointed out an important consideration regarding scan time. It's essential to strike a balance between ladder logic efficiency and scan time for the specific application's requirements.

I recommend checking online marketplaces, forums, or classified ads related to industrial automation and PLC equipment. These platforms often have listings from individuals who might have the items you're looking for available for testing. Make sure to specify your requirements and budget when posting your inquiry, and you might just find the right fit for your needs.

Technical support / Re: HOSTLINK COMMAND & EXCEL IMPORT

Hi Tech
           Thanks for your response on this, although I had tried the link on a pc and a laptop with no real joy. I then tried it on yet another PC with excel 2016 and as you say it works fine and quickly. For whatever reason it seemed peculiar that it did connect to nano's without a problem so I did not think to try other versions. I think there could be some issue between my excel 2010 version and my operating systems. My Laptop is on Win 10 but my PC is on Win 7. So many legacy software issues I have not got around to the upgrades yet.

Anyway this excel link is a fantastic feature and I would recommend it to anyone for data logging etc.

Thanks for your Help

Hi,
Using the command GET_IPAddr, you can store the IP address of the PLC in any Data Memory (DM) address you want. Just make sure to change the 20 to the DM address you would like to use.
Hope this helps!

How do you access the PLC data from Excel?

Could it because the web query that worked with Nano-10 was written for the IP address of Nano-10 but not Wx100? You may need to re-define the Excel query:

If you add a new query on the Excel spreadsheet cell by specifying the IP address of Wx100 and the query string, did you get the response data string correctly (see below)?

We tested that on Excel 2016 and it is able to obtain the correct response string from Wx100.

Technical support / HOSTLINK COMMAND & EXCEL IMPORT

Hi Tech
          Seem to be having a little trouble with importing data from a wx100 using the hostlink commands. I have a spreadsheet setup which can happily connect to nano plcs on our network. When I tried to connect to my wx100 using the following web data link - http://153.52.35.180:9080/HOSTLINK/RVIA* - all works well and good at
the web page level. However, when I try to import the data to an excel cell the machine just keeps on trying and eventually comes up with a message that the data cannot be connected. This is strange because when I just simply use a web browser the expected data appears correctly in the web browser window. I them went and tried the same exercise on another pc and whilst I can again happily connect to nano plcs on the site and access data from the same integer location within the plc, then all is well and good, but then when I try it on the wx100, it seems to lock up just after clicking the import option. It seems as though there is some conflict at the excel
import stage??
