What PLC are you looking at Boyan?
.
Sometimes you have to use a PLC, and other times it just makes life a bit easier.
Mach 3 only has a 10Hz refresh rate for Macros, which means any sort of ATC with critical timing can't be done directly. I used a PLC for the turret on my lathe, as the locking mechanism timing needs less than 50ms between sensing an input change and an output being activated, which wouldn't be possible with a Mach 3 macro.
Mach 4 does have a faster refresh rate, but I'm not sure how fast it can react.
.
However most ATCs on a Mill aren't that time critical. It's a just a relatively simple process cycle, with the biggest problem likely to be how long it takes. It's just a case of working out the required sequence of sensors and outputs.

I was just thinking aloud.

I know you have already made a decision.

Is this some kind of British sense of humour or a lack of one?

No offence intended, yes blame the British sense of humour!

Humour. Guinea Pig = slang for tester.

I thought I'd missed a link.
Other option is their range of Click PLCs, which are cheaper, but are a bit more limited in terms of supply voltages, but the programming software is completely free (I see the DL05 software is limited to 100 words).
