MNETCR.UTIL
The following sections describe each of these controller tag structures in more
detail.
3.4.1 MNETCR.DATA
The controller tags in MNETCR.DATA hold data to be transferred between the
processor and the MVI56E-MNETCR module. This read and write data is
transferred between the processor and the module as "pages," or blocks, of data
up to 40 words long.
The data types for the MNETCR.DATA.ReadData and
MNETCR.DATA.WriteData controller tag arrays are integer arrays containing
variable numbers of elements.

MNETCR.DATA.ReadData
ReadData is a controller tag array that automatically adjusts to match the value
entered in the Read Register Count (page 44) parameter of the configuration. For
ease of use, this array should be dimensioned as a multiple of 40 words. This
data is paged up to 40 words at a time from the module to the processor. The
ladder logic places the received data into the proper position in the ReadData
array. This data is used for status and control in the processor ladder logic.
