The Structure of Process Image Input and Output Tables
Information about inputs is stored in the process image input table (PII). Information about outputs
is stored in the process image output table (PIQ).
The PII and the PIQ each have an area of 128 bytes in the RAM memory.
The PII and the PIQ have identical structures. The PII and the PIQ can be divided into three address
areas as shown in Table 6-3.
Table 6-3. Structure of the PII and the PIQ
Slot Number
Digital modules
0 to 31
Unassigned address space
Module
Byte Address in the PII
and PIQ
0 to 31
32 to 63
64 to 127
Analog modules
0 to 7
•
The address space for bytes 0 through 31 is reserved for information from or to modules that
are addressed like digital modules.
•
The unassigned address space in bytes 32 to 63 can be used to store intermediate results.
•
The address space in bytes 64 to 127 is reserved for information from or to modules that are
addressed like analog modules.
