88 SM-Applications Modules & Motion Processors User Guide

Issue Number: 4

GETPARATTR

This is used to get parameter attributes such as maximum and minimum values, read-

only flag, etc.

CModeXfer

This allows the user to change the drive mode without any fitted option modules getting

a hard reset. It allows for a smoother drive mode change. While the drive mode change

occurs fieldbuses will not be able to write to parameters and this is handled at system

level. They will NOT get a ‘write to parameter failed’ message during this period.

These commands are implemented to allow the user to utilise the SM-Applications,

SM-Applications Plus and Digitax ST Plus modules Modbus RTU master functionality.

PFIXREAD6/PFIXWRITE6

These blocks provide reading and writing of drive parameters in a fixed precision of 6

decimal places.

ANSIREPLY

This command existed in the UD70, however the syntax has changed for the Second

Processor.

It is a EIA-RS485 port function which is used in conjunction with the ANSIREAD and

ANSIWRITE functions.
