CS-Lab / Re: CSMIO I/O both Sink and Source

Outputs seem to be source only(PNP).

Hello Acrodoc,

I am not Hood but I can confirm for you that you can use both PNP and NPN transistor outputs because every single CSMIO input is fully isolated so inputs do not have a common ground or whatever call it.

So, there is absolutely no problem to either break the + or break the -.

If you have the signal as negative(0V), then wire to pins 14,15,16... and connect +24V from the power supply to pins 1,2,3. The opposite, if you have positive logic, then connect your sensor to pins 1,2,3 and put 0V at 14,15,16.

The only thing you should pay attention to is to not change the polarity.

My machine is wired exactly this way - 6 inputs are with pins 1,2,3,4,5,6 connected to +24V from power supply and I get the 0V to 14,15,16,17,18, 19 from limits switches.
The rest 6 inputs are positive logic -> emergency stop, alarm reset, etc...

In summary, connected whatever way you want (+ or -) but be sure to connect +(24V) to pins 1-12 and -(0V) to pins 12-25

Sorry, Еnglish is not my native tongue although I've been studying it since my early school years. Sometimes phrases are not the same from my native tongue even though I have adapted them to the English way and they sound good to me.

I think I have enough information to finish the wiring and make some trials without load attached to the shafts and confirm everything is working.

Maybe in a week or two we'll have the full system operational for first tests.

It looks pretty good.

What is this mach screenset because it looks very good?

Don't you have problem with flies landing on your touch screen and activating controls? Also, what about dirty hands?

I install HMI touch screens on various machines and based on experience, they don't live too long before certain areas become less sensitive to fingers.

My friend with the Mach machine also has a touch screen but due to the above problem and the touch screen itself too sensitive, it almost crashed once so he had that option disabled.

Hood, you couldn't write it in a more detailed manner.

Thank you very much. I am about to complete the wiring and make a test trial with 2 drivers(the rest are somewhere on the road from Germany to here) without mechanical shaft coupling.

I will write more when I have some results or I get stuck.

@ger21, thanks for replying.

I understand what Hood said from physical point of view.

As you and Hood said, one of the ways is to communicate via ModBus:
1) send command to the PLC to ref all drives
2) all drives ref in sequence Z -> Y/X -> X/Y
3) (optional)confirmation from the PLC


if (3) is optional, it is up to the operator to verify everything is OK and not move the machine without homing being finished.


My continued question was more about the way Hood connected the PC and the external PLC. I have the CSMIO via Ethernet to the PC but surely my RS-232 is not occupied and can be used as an additional interface. Also, I recently bought from EBAY USB->RS-485. Although it costs $2, I may give it a try.

In summary, the ModBus connection would be the best solution, I just need Hood to confirm the way he did it. Maybe the ModBus settings in Pins menu are independent and they don't interfere with CSMIO. RS-232 will also work for me as it is just the PLC I need to wire. The PLC itself will be wired via RS-485 to all drives and will read voltage, current, torque and other data which will be visualized at a later moment on a display or if I get better with VB Macros, maybe I could get them to the Mach3 custom screen. I haven't got into details so far but have good idea of the capabilities of ModBus protocol although I tend to be more a mechanic now

Thanks,

if you find some information about yours, just let me know because not touching the mouse for override is what attracts my attention.

In fact, I've wired also external start/stop/hold buttons to minimize the use of the mouse.

How have you connected it to Mach? Should I connect it via RS-232/RS-485 to the computer or somehow to the CSMIO? The only way I see is the spare "Expansion" connector but the CSMIO manual clearly states nothing other than products of CS Labs should be connected to this connector.

If I wire the PLC via RS-232 to the PC, will I be able to specify it in Port & Pins correctly and will it work together with CSMIO simultaniously?

As for the home switches, they are currently connected both to CSMIO and the corresponding servo drivers before I figure out the final work pattern. In fact, I could easily remove them from the CSMIO and free some space.

But I got attracted by the ModBus connection of a PLC to Mach3 working together with CSMIO. Please throw some more light Hood, thanks.

1. So you confirm that the shielding should be connected to the Earth of the panel, where all the other consumers and not to forget servo drivers are also connected to their earth?

3. I'll check if there is internal link with the multimeter, maybe the terminals are organized in a way to directly connect potentiometer.

4. Do Log Pots are also 4,7 kOhm? I don't have much experience with potentiometers at all and didn't find an example in the CSMIO manual, it is just mentioned that you can override G-Code values for feed and speed via potentiometers.

Thanks Hood for the sample source code.

I so much lack the possibility to connect via ModBus other devices to the CSMIO. This way I would do it very easily for each axis.

The workaround here would be to send just 1 single signal to my PLC, leave it do all the job and return a signal back although I don't have enough spare to be honest. But if precise homing works, then the 3 home switches may not be connected to the CSMIO at all and make 3 more inputs free.

Anyway, I would try this idea, thanks for sharing.
