Thought they must have been fairly small with the size of the power supply.
Yes ModBUS is easily forgotten, I just got another PLC to use on the Beaver mill and took me ages to remember how to set it up.

For anyone thats interested here's the M6Start macro for the 4 station turret on my Hardinge.

It passes the requested station # to the Cubloc PLC via a holding register mapped to 66 in mach and D12 on the Cubloc.

The Cubloc always has it's actual station # available in D13 (67 in Mach) via it's turret encoder routine.   = 0 when invalid = 1 to 4 for valid stations.

I'll probably post the Cubloc program when it's developed a bit more.

The Macro below is partially based on Hoods Churchill Macro.  Thanks Robin...

Well more macro's in the works at the moment.

I can't remember the allowed custom macro rules for mach, I just been working on Collet open and close macro's.   Ideally I'd like to use the more conventional M10,11.   But they seem to be reserved for something (Probing?)

Even replacing those with my own, the new ones seem to be ignored.   I was able to use M20,21 though !   Thats also normally an clamp/unclamp signal on many machines.   But I think for Indexers.

I don't really want to start using high number M codes for those that are very conventional.

 I used M13 and M14 when I had the Hydraulic chuck on, not sure why I chose them, maybe just next available not used M codes, or could have been what the original used, will have to look at the old manual and see.

Here's the Clamp/UnClamp macro's just in case anyone could use them.

I think the Sleep() command takes it's Argument in milliseconds??

More stuff here.   This time the Diagnostic/In progress version on my Cubloc code.

I'll update this as I make significant alterations to it.   But might come in handy to anyone starting out or struggling with the Cubloc PLC's.

Mostly in Cubloc basic.   Some ladder will be added later.

Also a pic of the cubloc study board just about fully loaded with every switch and Led used up to test the logic on the desk.   Everything has been connected to match the IO assignments on the CUSB36R PLC.

The code below has been updated here a fair bit.   BUT BE AWARE is has a lot of diagnostic code included.  e.g the Pendant stuff which enabled me to test the toolchange routine when not connected to Mach.  I ran out of inputs and had to use the Estop input for the 4th button!   This obviously is not staying like that as I have no use for the pendant on the real machine.

Hood.

The Study board is.   The CUSB36R is 24v able via the onboard opto's.   

http://cubloc.com/product/03_02cusb36r.php

you can also get it in the UK for £100...

How does Mach communicate with Cubloc?
Looks like a nice package and at £100 its pretty good value.
