How uses Mach3 the button or i/o with supports modbus plc to carry on the pair? Whether some mach3 and a modbus agreement comparison form?
For instance: Estop-->modbus0x0000
And I use one to support modbus PLC's  I:0.0 electronic contact to make Mach3 Estop the input, known PLC I:0.0 receives an electric shock the modbus address is 0x0000, how establishes?

you have to translate your Octal addresses to Decimal equivelents in the Modbus Configuration, your base decimal number is also your Loacal Varible in modbus in mach, as Modbus 0 on the inputs, it increments in sequence by one for each function after that.

Thanks!
The Mach3 each function like ¡°X limit¡± button, how establish in MOdbus Configuration? Whether to cite how many examples to me?
Has all Input signals, Out signals in the mach3 correspondence modbus address form?


how in mach3 input output does signals correspond modbus?
Sorry, my English is disappointing

Yes, it is true, I am having a hard time following you english, but I am sure that I could NOT do the same level of competance in your launguage, since I dont know any others...........hehehehe

What you want is called "Brians", it is a subprogram in mach, goto the "Operator" menu in mach, scroll down to Brains Editor.
In brains you translate what modbus address (local var), goes to what process (terminator) for inputs, or what Mach process goes to what Mobbus (local var) address for out puts.

I highly, highly, highly recommend you watch the vidios under the Support forum website under the "support" button above.
click on vidios.  watch the vidios on how Modbus works, and watch the vidios on how Brains works.

this is question vedio.
Can you gives me "setup modbus Vedio",?with the English explanation document??grateful extremely!!!

You will have to use Microsofts built in file compressor, or just post your questions on this site. I do not have the WinRar utility, nor will I buy it.

so repost your questions

scott

Look at this weblink under the support forum "vidio tutorials"

click on these subjects and watch each vidio:

1). Introduction to Modbus
2). Serial Plugin Modbus
3). Analog inputs bia modbus
4). Introduction to Brians
5). Advanced Brians
6). Brians and MPGs

Those above will answer all you questions

Further the Function in Brains for "Bit of Word" bit0-15 currently does NOT work. So you will not be able to use it with the PLC you currently have. It appears to me that all your inputs are Bit Of Word in a single register, same for you out puts. So, you only have ONE option to use the PLC you have with Mach, IF you PLC has some Varible Memeory ranges, then you can write or Read one output or input to a register.  I.e. if you need a discrete output then Write that output from Brians to the terminator Modbus address "0" for instance. In your PLC bring that in to varible register (*********0.0), then the next output will map to register (*********1.0). This will be inefficient since you will have to use an entire word of varable user memory in your plc. But until "Bit of word" is fixed in the Brain application that is what you are stuck with. Brian (the current developer of Mach3), said he will get to it somewhere down the line.

IF you PLC does NOT do Bit Of word for user varible memory then you will have to buy a different brand of PLC that will. I would Highly recommend Automation Direct  DL 05, or DL 06 depending on how much I/O you need.
