Hi everybody,
I have some questions to you about modbus in mach3.
In the last weeks I built my own modbus pendant.
http://festplatte.aon.at/a/filemanager.get/395362/handrad.bmpIt works very well at mach3 V2.01.
In mach3 V3.00 I have many problems.
In the Yahoo board I found out that the timer of
Tickctr was changed to a 200µs 16bit wrap-around timer.
That all I programmed also on my pendant.
But now to the Problems:
When I uncheck the "modbus plugin supported" I get a big step
at the velocity by a rollover.
Here is a short video , there you can see the big step.
http://festplatte.aon.at/a/filemanager.get/714339/rollover.aviIn a email , Art wrote to me that i should enable the
"modbus plugin supported" checkbox.
When I do this , the rollover step is ok but then my
macropump is not working.
2 examples:
Dim fro as Integer
fro = GetInput (64) 'Analog_1 read
fro = fro /4.13 -3
SetOEMDRO 821, fro
Of course this I can do with Brain contol
but for the next example I can't find a solution in BrainControl .
'X-Dro Value to modbus
Display = ""
SVal = Right(" " & Format(GetDro(0), strFmt),9)
Display = "X" & SVal
SetModIOString (1,0,0, Display)
I found the "sendstring" Commando in BrainControl . Using this Commando I can send a
text but not a value of a DRO to modbus.
Have somebody a answer to my questions ?
Sorry for my english , it's very bad
Best regards from austria
