MNETC.DATA.WriteData
The WriteData
controller tag array
size should be equal to or greater than the
value entered in the Write Register Count (page 44) 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 95).
