N42

This N-file lets you read and write some values configuring the port

N42:3

Time-out (read/write): Time (in seconds) allowed between messages to the N41
file. If the module does not receive a message in the specified time, it performs
the fault action configured in its Comm Flt Action parameter.

N42:7

Module Port Number (read only): DPI port on the drive to which the module is
connected.

N42:8

Peer Modules (read only): Bit field of devices having DPI Peer capabilities.

N-File

Description

N150 – N199 These N-files let you read and write parameter values in the DPI Host (for

example, an SP600 drive) as 32-bit double words. You can interpret the data
in various ways (for example, 32-bit real, 32-bit integer) To read a parameter,
you need to send a message with two elements. For example, to read
parameter 1, read two elements beginning at N150:2. As another example, to
read parameters 2 - 6, read ten elements beginning at N150:4.
