in Table A.6 Advanced Device Configuration.

User-Configured Data Table

If your application requires monitoring a small number of parameters
normally found in different data tables, and you need to conserve
communications bandwidth, then the Powermonitor 3000
user-configured data table may be an ideal solution. To use this table,
your data client application performs a write to Table A.30
User-Configured Table Setup,
containing the desired parameters that
you select from Table A.59 Parameters for Trend Log and Configurable
Table
. To read the user configured table, perform a table read of Table
A.31 User-Configured Table Results.

The user-configured table setup includes the following elements:

Password: needed to change the configuration
Table identifier: a number that identifies the results table. For

DF1 and Ethernet PCCC/CSP, this is file number 31; for
EtherNet/IP, DeviceNet, and ControlNet, instance 37 or 1 (see
User-configured I/O table below)

Parameter selections: from Table A.59. The first zero ends the list

of parameters

Table A.31 will return 14 elements (DeviceNet units) or 23 elements
(all other communications options) containing the parameters you
specified. You may specify more than 14 elements in DeviceNet units
but it will return only 14. The results table data is in floating-point
format. The first zero-valued element in the configuration write
determines how many meaningful elements are returned in a read of
the results table.
