MNET.DATA.WriteData
WriteData is a controller tag array that automatically adjusts to match the value
entered in the Write Register Count (page 43) parameter of the configuration. For
ease of use, this array should be dimensioned as a multiple of 200 words. This
data is paged up to 200 words at a time from the processor to the module. The
ladder logic places the write data into the output image for transfer to the module.
This data is passed from the processor to the module for status and control
information for use in other nodes on the network.
The WriteData array is related to the contents of the Write Data area of the
module's internal database. To view the actual registers in the module's internal
database, access the database display from ProSoft Configuration Builder's
Diagnostics menu. For more information, see the section on PCB Diagnostics
(page 96).
