Modbus / Re: Homann Modio config error
« on: June 05, 2014, 03:53:23 AM »
Read it, scanned it several times each day, particularly when writing a response. Printed two copies, one next to the lathe, one on my desk, both annotated and pages tabbed etc.

BUT will continue to reread.
Found the detail of Pins 1 &2 in the release notes posted on the Yahoo group, but not as yet found direct or specific mention of what the other settings of the HEX switch do.
Guess I could set the switch, see if it still communicates and if it does read the config registers and overlay the bitcode to the function.  Then there would be an easy table of each valid HEX switch setting and what it enabled/disabled.   BUT as yet not found this level of information in the manual, like you say will reread.

Where do I find, or is it ask, additional info, like on the other settings for this board?

I think the capability of this card is great, so don't keep it hidden please, publish more documentation.  What do the other switch positions enable?

Will order another to put on the mill also, when I have finished the rest of the Lathe.

Best Regards Peter

I am there.  By pins 1 and 2 you mean physical connections pins 7 and 8  DIn 0 and DIn 1   !!!!!!!!

By which 2: then reads a value, Bottom RHS of LCD
 and on connection to PC/Mach3, tab to MPG & Brain turned on etc  MPG2 works, Thanks.

Where have I missed this as a set-up? since manual give MPG2pin as different?
Does this mean I can run Digispeed AND both MPGs since now not pin contention ?

Happy bunny !!!!
Thanks again.

Input strip plugged back on.
Rotating, slowly the MPGs, one at a time it is possibly to see four state, Corresponding to the LEDs of the MPG signal reflected in the most significant digit, first digit, of I= display. eg 30, 70, B0, F0
And C0, D0, E0 F0

Information/state  ok at input just not there at 1155

S1 also works for input from one of the MPGs

Just Power and LCD connected.

I= 00
then short D in 0 reads 01, short Din 1 reads 02, short Din 2 reads 04, short Din 3 reads 08
Short Din 4 reads 10, short Din 5 reads 20, short Din 6 reads 40, short Din7 reads 80.

Further to this short a pair of pins and displays the sum. Also Short An1, 2 or 3 and reads 0000 on corresponding display

What next?

Regards Peter

Away from machine today will do as requested tonight.
However further investigation yesterday, got LCD back to status display, disabled brains.   The three A-D read ok and the MPG and switches change the values.

Will do the same in isolated mode and record the detail of the display.

Thanks for all the help.  HEX switch on 0, but could the core code be not the default,  Reading the pins but doing the wrong maths?   ( what I don't understand from the manual is if a new configuration is loaded how where is that stored, such that 0 is not over written. I assume Hex switch should be set to a vacant position and that loaded and reset. Seen no notes on this, at this stage have enough layers off the onion  and the default should do just fine for the controls I have.)

Peter, third digit of 1151 changes with movement of either MPG

8 registers from 100Hex screen dump attached

I am on the right pins at the Modio card end  12,13,14,15 for MPG1 and MPG2

Register 1155 does not change to MPG2 being moved.

Appears you already answered this?
Communicated with Chris
"The problem in Mach3 was eventually fixed in Feb 2011 in Rev 3.043.030.  I currently use (on Hood’s recommendation) R.043.056.  Later versions of Mach3 have reported issues, so I no longer update.  I am happy with, and will continue to use R043.056 on both my mill and lathe.


Here is a link to my thread in the Mach3 forum which outlines the history and subsequent fixing of the problem:
