MNETC.DATA.ReadData
The ReadData
controller tag array
size should be equal to or greater than 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
200 words. This data is paged up to 200 words at a time from the module to the
processor. The
ladder logic places the data received into the proper position in
the ReadData array. This data is used for status and control in the processor
ladder logic.
The ReadData array is related to the contents of the Read 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).
