ISM7411 Ethernet streaming protocol

[cmartinez]

I need to control ISM-7411 Ethernet Stepper Motor with Ethernet streaming commands.
I tried to find documentation about this, but without result...
ISM-7411 use a standard protocol and what it-is ?
Is there a manuel to explain all commands I can use ?

Thanks,

Hello,

The device can be used as regular drives with NI Softmotion

Hello,

I already downloaded these manuels, but for my application it's not usable.
I want to drive the motor with micro controllers through the ethernet link.
Unfortunately I can't use Labview under windows.

With the NIStgepperConfigurationUtility I saw with spy ethernet utility some ascii commands like :

"HR", "CM21", "SK", "DI25000", "VE1.00", etc...

These commands match with some "Max Family Motion Controllers" commands but not all and some are differents.

It seems that they are two types of commands ascii and binary :

1/ All ascii commands are prefixed by "00 07".
2/ All binary cammands are prefixed by "00 08".

My request is to have a documentation of these internal commands.

Hello,

Finally I found for ascci commands this documentation Host_Command_Reference.pdf

All commands seem to be match with commands we can send with UDP frame to motor.

Example for change shaft speed for point-to-point move commands like FL, FP, FS, FD, SH, etc : "VE1.00" Set move velocity to 1.00 rev/sec

I send UDP frame like this (in hexa)  "00 07 56 45 31 2E 30 30 OD" in blue it is the ascci command.

Now if there is someone can have information about binary command like this "00 08 xx xx xx" that would be great.
