PoKeys / Re: New Pokeys 56 Modbus config with MACH

« on: April 30, 2011, 03:24:06 AM »

Hi, an update for the outputs problem. If for some reason one or more of the outputs starts inactive, say the LED connected to it is OFF, when I do a write to some of the output-coils addresses all outputs go active. Then write does not work to bring them inactive.

I guess something is not enabled somewhere to be able to write to an output. Yes, I have checked read/write options for the DIGITAL I/O on the PK soft. Any ideas?

Hi

The whole thing is getting quite funny to configure. Now I cannot access outputs through MACH3. They work with the PK soft anyway.

Another strange thing is that I assigned two buttons via Brain to JOG X + and JOG X -, but whenever I push any of them it starts jogging continuously till I hit reset. Did I miss something about this?

Thanks

Hi, after a lot of reading to your last post I finally got it.

So when my analog inputs are at cfg#1 starting at address 10 and I have a local Var of 0, my first analog input is at Modbus 0, cfg#1. I first thought it should be at modbus"10" in the brain, that's why I did not get any data.

Everything is fine now, it is a matter of some "brain" work to do what I want.
Maybe when I setup everything I will post my configuration here so other people should not pull their hair so much. I cannot remember how many times I changed settings, created and reloaded brains the last two days. Aaaah, and another thing I found during the process - one cannot save a brain named with numbers. It gives ARTCODE 9991 and shutdowns MACH when the brain is enabled. This was another hard moment, which took me quite a time to realize.

Thanks again!

I read the Brains Users Guide, this is some good doc.
The PK is used with the TCP Modbus as it should. I made a simple brain, using the first 3 pins on it with some switches wired and it is working. These were configured as inputs 0-2, as it is 0-based, so far so good.

Now I have trouble getting data from the analog inputs. I wired a POT to pin 43 which is at address 12 on the registers. I did test it on the modbus testing page and it is working, giving a DEC values from 0 to 4091.  I watched the video for macropumps but it was intended for the ModIO card, so "getinput (64)" returns the value of the analog input 1, wired at pin 2 of the device. I found this on the ModIO manual, but did not quite understand, is this 64 value some sort of register or what?

The question now is what I enter after "getinput" to get data from the analog inputs of PK? I could not find info on this VB command.

I have made 2 configurations on the TCP Modbus dialog box. Config0 is 10 registers starting from 0 as discrete inputs, and Config1 is 7 registers starting from 10 as input registers. The second config is for the analog inputs.
This is another thing I doubt about. Since the PK manual says 0-54 addresses are discrete inputs, but 10-16 are analog inputs, do I have to make 2 configurations - one starting at 0 with 55 registers and the other at 10 with 7 registers?
Or I have to make 3 configs, the one 0-9 registers, the other 10-16 for the analog inputs and a third for the rest of the discrete inputs - 17-54?

The more I get into this, the more questions get generated here but gradually I am making some progress.

Thanks for the info

I managed to read data from the device, entering the correct register address in the field, so I am sure MACH3 sees it. I guess I will have to watch the tutorial videos again to understand what needs to be done next.

I am running mach3 in simulation because I have installed it on a 64bit ver of win7. I am not sure if it will correctly manage I/O in that mode. Maybe I'll have to move to the XP machine.

PoKeys / New Pokeys 56 Modbus config with MACH

« on: April 19, 2011, 04:57:07 PM »

Hello, I am trying to configure mach3 and pokeys56 to see each other though the modbus interface. So far I have nothing but headache. I installed the device with the IP of 192.168.1.4 and made a connection with the control software. Everything works - digital inputs, encoders, analog inputs, etc.

First of all I started with the Modbus serial control monitor but have trouble understanding the correct slave address and start address values for the pokeys.

I watched the video for mach3 modbus config but it was intended for serial connection. I read through the manual, machsupport forum and wiki, but could not put it all into work. Will be glad if someone points me where to start about learning the mach3 to pokeys modbus connection.

This is done easily with a 7474 trigger IC, 2 are needed for a 4 axis system,

Hi, I'm Todor

I've been using MACH for the past 3 years and will say it's a great software that is available and affordable for the average cnc user. The support is great and the bug fixes are released fast. Thanks for all the work done there.

I am currently building a wood router, gauntry type and have struggled quite a bit with the DIY servo drives I decided to go with. Anyway, the metal work is almost done, will have to do some massive wiring to get the thing moving.

Regards
