SETTING UP KFLOP, KANALOG FOR NEW CNC ROUTER RETROFIT

[NOELNOG]

Hi Tom

Is there a function to watch the value of the axes read outs, for example when performing tool change, if the X axis moves 70 inches near magazine, do the next step and continue, but if for any reason the axes doesn't get to 70 inches the tool change operation must stop, is any function to add to the atc c. program for that?

Hi Noel,

Its not clear what you are trying to achieve. Normally if you command an axis to move you will wait until it is completed.

Do you have encoders? If so and the axis doesn't move properly you should get a following error.

You can monitor the commanded position in counts as ch->Dest and the actual Position as ch->Position.

Hi Tom

How can i enable the A or B axis to tangential, i have a spindle with rotary aggregate for use with saw blades, and 90º cutter bits.

Hi Noel,

You might see the Tangent.c example.

Hi Tom.

I am dealing with a large cnc machine, where lots of valves and sensors are located in 3 spots of the machine basically, it actually uses sercos communication with optic fiber cable, but that is going to be replaced with modbus RS845 remote modules, i have read that kanalog supports RS232, so i don't want to run hundreds of feet of cables to my konnect cards. just asking to make sure if I can do this?, i have found lot of IO's remote modbus modules in google, so can i remove my konnect cards and use the kanalogs Rs232 with a converter to RS485 to communicate all that bunch of sensors and valves?

this is one of the I/O remote modules I liked, what is your opinion about it?

I've had one of those Waveshare modules sat on my bench for a while, but still not got around to setting it up (Modbus is one of the major things I want to get coded into my software, but I've had to take a bit of break from that for now to get some studying done).

I've used Modbus in the past with a Kanalog, over RS232, to talk to a Click PLC.
You'll need a RS232-RS485 converter, then it's a just a case of figuring out what registers you need to address via modbus, and copying those registers to/from suitable variables in in the KFlop.

I'm sure Tom will be along shortly to suggest upgrading to a Kogna, as they have a RS485 driver built in...

Thank you Moray

yes I have to try with Kanalog and RS232 to RS485 converter, is out of my budget to upgrading to kogna for now, i just looking for a good and not very expensive modbus I/O modules, otherwise i would have to run 3 sets of 20 cables each along 70 feet over the machine.

Hi Tom
regarding to modbus communication, can i use one the example c.programs to configure my slaves? this is going to be a challenge for me, but i have to try, if i don't want to run hundreds of wires on my machine. to this point I know kanalog support RS232 output, and I need to get a converter to RS485, I found a modbus rtu IO devices and want to order em soon, but i still have doubts if they will match to Kanalog. can you give me your opinion about this please.

this is the IO module i want to order, i would need about 8 of them for all my inputs and outputs

It should be possible.

I have found the RS232-RS485 adapter, so if I get some time, I'll wire it up, and hope the KFlop 3.3V RS232 is good enough for the adapter.
Failing that, I'll need to clear some bench space to get a Kanalog setup.

Thank you Moray

I think for now i will go with wiring direct to Knonnect cards, i running out of time and customer is waiting for the machine, maybe for a future projects i would try modbus in some way.
