Hi Ben, Sorry, I have only just seen your reply, no worries on the chips, thanks for looking into this. I have just updated to FC9 and I have just tried the update in both FC8 and FC9 and I am afraid I am still having problems. I have started again in both FC8 and 9 and written a simple loop that ju...

Hi Ben,

I have just managed to catch todays post. They are on their way to you.

Hi Ben, Thanks for this. As I said I did note that the properties show port A and I am sure they used to show GP as on the data sheet, how this translates into the .hex file I don't know and it may make no difference. If you are stuck for a chip, I have a draw full of them, I can easily send you a c...

Hi Ben,

Sorry no joy, I have updated the complier, and I am pretty sure it updated as my firewall created havoc, that fixed and I can program the PIC either with Clock out or not and I can see the change on a scope, as before, but still no output.

Any other ideas?

Thanks

Simon.

Hi Ben,

Thanks very much for this, I will give it a go when I am back in the workshop and I will post the results on here.

Hi All, Just wondering if anyone ever got to the bottom of this as I have just fallen in to exactly the same rabbit hole, before I looked on here. Unfortunately I can no longer get FC6 to run on my laptop so I don't have the option of going back to it to modify the code I wrote previously. I have al...

Hi Viktor, Modbus Poll is $129, I purchased Poll and Slave together and it was £167.40 UK all in. The website is https://www.modbustools.com/order.html As I said, I have it working now but I can't set it up so that I can look at multiple Slaves together, I can only look at one at a time, although it...

Thanks again for your help Abhi, I have this working now. I can't display all of the slaves on the PC screen, using Modbus Poll, at the same time, but I can look at each slave individually, which I think will work with the PLC as the program can just call each slave individually. There is nothing fa...

Hi Abhi, Thanks very much for your reply, OK on the start addresses, I will give that another go, I have brought a Modbus Poll licence and I am wondering if thats whats causing my problem, it seems that I should be able to open several windows in it and look at different registers on different slave...

Hi Abhi, Thanks for this, I have already seen this link, but it appears that this is just a master talking to one slave. I have that working fine, it's adding additional slaves to the mix that is causing me the issue. Modbus Poll flags up an error if you re-use the same addresses for additional slav...

Hi Abhi, I appreciate your help with this. I have attached the code I have working as a master- single slave setup, not that there is much of it at the moment, the Modbus part is the bit that's new to me, so I thought I would get that working first. I know that the code isn't quite correct to elimin...

Hi All, This is my first time posting so please forgive me if I am posting in the wrong place or way. I have hunted through the posts and help pages but can find no help or instructions on this. I am making a device that uses 10 identical PCB's that collect data and using Modbus RTU over RS422 send ...
