2.2.1 Status Object (PDPSInStat Data Structure)
This object views the status of the module. The PDPSInstat object shown below
is updated each time a read block is received by the processor. Use this data to
monitor the state of the module at a "real-time rate".
Refer to Status Data Definition for a complete listing of the data stored in this
object.
2.2.2 User Data Objects
These objects hold data to be transferred between the processor and the MVI56-
PDPS module. The user data is the read and write data transferred between the
processor and the module as "pages" of data up to 200 words long.
The read data (ReadData) is an array set to match the value entered in the Read
Register Count
parameter of the PDPS.CFG file. This data is paged up to 200
words at a time from the module to the processor. The ReadData task places the
data received into the proper position in the read data array. This data will be
data sent to the module by the PROFIBUS Master (PROFIBUS Outputs) and can
be used for status and control in the ladder logic of the processor.
