Organize Controller Data for
a PanelView Terminal

Organize data for a PanelView terminal based on how the data is used.

To access the I/O tags of the PanelView or PanelView Plus terminal, use the
following address format.

Table 23 - Controller Data Organization

For data that is

Do this

Time critical (for example, data that

controls a machine)

Use the I/O tags of the terminal.

The tags for this data were created when you added the terminal to the I/O

configuration of the controller. They resemble the I/O modules’ tags.

Not time critical

Create arrays to store the data.
1. For each screen, create a BOOL array with enough elements for the bit-level

objects on the screen.
For example, the BOOL[32] array gives you 32 bits for push buttons or
indicators.

2. For each screen, create a DINT array with enough elements for the word-level

objects on the screen.
For example, the DINT[28] array provides 28 values for numeric entry
controls or numeric displays.
