SIE.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 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 121).
