Hi Ian,

We are talking to 2 slaves with the plugin Modbus at the moment with no issues, Using a RS232 to RS485 interface.

I am using User LEDs only to command the start of homing to the drives. You are not allowed to change standard LED's state at will so User LEDs were the way to go.

You can only access consecutive addresses in the PLC from what I see. In the above screenshot (taken from Scott's manual, by the way) you can see that different addresses in the slave are being accessed: 2000, 1000, 5000, etc.

Also can have several slaves at the same time (PLC, two servo drives and a VFD).

Please correct me if I am wrong with any of the above

LOL... got distracted and forgot the attachment.

Still this one has the addresses spread on a wider range than I could do with the non-plugin Modbus. Or, I hope, I am wrong.

This sounds good! Still not sure how to work with it. See the screenshot. How do you do the same in the non plugin version? Accessing numerous different addresses in the slave?

Is it a screenshot of your actual machine settings? You're using 8-1-N, while Scott strongly suggests 8-2-N.

Honestly, I don't know. Was just reading some posts by Scott (poppabear) where he strongly recommends using the plugin. Thought he must know something. Think without the plugin it's not stable or reliable...

What are the commands you're using in the VB? SetModOutput and GetInput? Also not sure how to work with the non plugin Modbus. Information seems to be lacking. Can you use Brains too with the non plugin version?

Using LED's for that since I don't know of another way. Talking to the PLC over Modbus with Plugin Enabled and as such it doesn't allow sending outputs from VB and reading inputs. Unless I am doing something wrong of course.

Hi Hood,

Mach version .062.

Simple Threading Wizard. Normally, unless you installed additional ones, there are only two in the list - Simple Threadin and Turning. I probably should have checked the Turning one as well, but I didn't. I reckon it would be the same with that one as well.

LED numbers 1003 and 1005.

In the mean time we added a safety feature - a hardware button that goes directly to the PLC and the PLC would wait for both that button and signal from Mach to start homing. Don't think we would revert this and use merely the signal from Mach as we can't trust it anymore after seeing this happen. Who knows what else could then trigger those LED's. What if it would happen with a boring bar inside a part!

Very, very strange and scary!

Witnessed a very strange behaviour today - a potential cause for a disaster! It's on a lathe which does homing internally in the drives and sends back a command that it finished. To send a command to the drives to start homing we used User LED's in Mach which we turn on in the homing buttons and a simple Brain sends the LEDs state to the drives. LED ON -> Send command to drive -> Start Homing -> LED OFF.

Want happened today was the LED's going high when opening the wizards from the top menu, selecting threading wizard and clicking OK. As soon as OK is clicked, LED's go high and drives start homing. This is repeatable and happens each time exactly in the same way. How does it happen?! How is it that simple to UNINTENTIONALLY change the state of LED's?!

That's nice Tweakie. I am picturing a lot of mess after dealing with the toner Wink

He...he.. to keep an eye out on eBay, the least that's required is knowing what you're looking for - I didn't know the above brand up until a few hours ago Wink
