That will be because the PMC is continuously writing to that register every couple of milliseconds. So whatever value you enter is being instantly overwritten.

I modified the script on my system to update another register I created, and when I enter S1000 into the MDI the register updates. So I am not sure why this isn't working on your system..

i STILL CANT GET A RESOLUTION TO THE REQUIRED SCRIPT TO MAKE THIS OPERATE PROPERLY!

Hi,
have you thought about putting some code in the PLC script instead?

Yes definitely thought about it, but i am unsure as to how to write the code!  This is the main problem and why i'm here asking for help! if i was a scripting guru i would have written the solution by now lol

I have used the pmc editor a couple of times, but i am not sure how the structure should look to acheive the desired result

Hi,
I gave you the outline of what is required in post #8. Did you try it?

I pasted that code into the lua file for the spindle control, but I had no success with that unfortunately

I noticed you have posted about this kind of thing a while ago - Do you use modbus spindle control yourself?  If so do you mind sharing the script?

But it doesn't go in the spindle control file, wherever it is and whatever it is, it goes in the PLC script. The code is not completed,
you have to add some details, you'll not just be able to paste it in as is.

I don't use MODBUS on my machine but a friend of mine has a CNC pressbrake which I helped him the interface Mach4 to the PLC of the machine.
It does not have a spindle .
