The Module Editor Window
The NIM’s module editor window should resemble the following figure after you have
displayed the configurable parameters using the above procedure:
Values in the window are in decimal format by default. To display values in
hexadecimal, check the hexadecimal box at the top of the window.
Reserved Sizes (HMI to PLC)
The network interprets data from the HMI as input and reads it from the input data
table in the process image. This table is shared with data from all input modules on
the island bus. When the reserved size (HMI to PLC) value is selected, the range of
available data sizes (in words) appears in the window (see the above figure). The
maximum size includes both the input data produced by the island modules and the
HMI to PLC data. Therefore, space that you reserve for the HMI to PLC data—plus
the input data from the island bus modules—must not exceed the maximum value
shown. For example, if your input modules produce 10 words of input data, you can
reserve only the remaining five words (out of 15 maximum) of the input data table
for the HMI to PLC data.
