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
communication bandwidth, then the power monitor user-configured
data table may be an ideal solution. To use this table, your data client
application performs a write to the

User-configured Table Setup

table,

containing the desired parameters that you select from the

Parameters

for Trend Log and Configurable Table

. To read the user-configured

table, perform a table read of the

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 Ethernet CSP, and Ethernet PCCC/CSP, this is file number
31; for Remote I/O, file number (BT length) 62; for EtherNet/IP,
DeviceNet, and ControlNet networks, instance 37 or 1 (see the
User-configured I/O table)

Parameter selections: from the

Parameters for Trend Log and

Configurable Table

. The first zero ends the list of parameters

The

User-configured Table Results

table returns 14 elements

(DeviceNet units) or 23 elements (all other communication 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.

Refer to User-configured Data Table Setup by Using ControlLogix and
EtherNet/IP Networks on page 314

for a sample ladder diagram and

messages used to configure and read the user-configured data table.

Optionally, you may purchase and use RSPower or RSPowerPlus
software to configure and view the configuration of the
user-configured data and input tables.
