Communicate with PanelView Terminals Chapter 8
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.
Terminal Function Requirement
Writes the data name_of_terminal:I.Data[x].y
Reads the data name_of_terminal:O.Data[x].y
This address variable Is
name_of_terminal Name of the instance in the I/O configuration of the controller.
x Element of the input (I) or output (O) structure.
y Bit number within the input or output element.
