Idn Objects

Introduction     An Idn object represents an individual SERCOS IDN. An Idn object is a container for data that is sent to and received from a Node. Methods are provided to get and set the data associated with an Idn object, but these methods do not actually transmit an Idn object to or from a Node.

Methods Create, Delete, Validate Methods   mpiIdnCreate Create Idn object   mpiIdnDelete Delete Idn object   mpiIdnValidate Validate Idn object

Configuration and Information Methods   mpiIdnCopy Copy all element fields of one IDN object to another.   mpiIdnFieldGet Get the value of an IDN (or all fields) from the drive.   mpiIdnFieldSet Set the value of an IDN field. The inverse of mpiIdnFieldGet.   mpiIdnNumberName Fill the buffer with the text form of the IDN number.   mpiIdnNumberText Get the ASCII representation of an Idn objects IDNumber (S-X-XXXX or P-X-XXXX)
