lol :) "but realistically for you probably no" This mean more than i would want to try and tackle? :)

The C program would have to be changed each time i want to increase speed or change rotation direction?

What i would like to do is M3,M4,M5 and S.

The drive has a Start Register 2331 with 2 Registers
and
Start Register 2330 with 1 Register. This is Hex format, i believe, going by Mach3 modbus testing.

As i understand it, the following is what each register does.....
2330 - speed
2331 - run
2332 - direction

Whould i need more info than this for a C program?

Hi Troy,   I meant to say "more than most anyone would normally want to try and tackle.  :}   But no the C program would not need to be changed each time.  It would dynamically create a string of characters to set the desired speed or do the required command.   I suspect those are modbus registers.  So if your Drive accepts modbus protocol then your C program would need to be able to talk modbus in order to formulate all the commands and responses (character strings) to be able to set a modbus register over in the drive.  Mobus is just a protocol for sending and receiving commands.  It is something like a packet of characters that contain address, command, data, checksum.   Depending on who is the modbus master or slave the program would either need to send commands or receive and respond to them.  We hope to have built in modbus support at some point in the future, but we don't have it now.   Regards TK Group: DynoMotion Message: 5323 From: Troy D Date: 6/24/2012 Subject: Re: KFLOP and rs232 Ok. Fair enough :) Curious as to how the mach 3 plugin spindle c program is handled by kflop?
