Memory Cards: Design and Function
Design
The memory card is somewhat larger than a credit card and is protected by a
robust metal housing. It is inserted into a slot on the CPU; the insertion direction is
determined by the design of the memory card.
Function
The memory card along with an integrated memory area on the CPU printed circuit
board form the load memory of the CPU. During operation, the load memory can
contain the following elements:
•
Complete user program including comments, symbols, and supplementary
information that permits decompilation of the user program
•
All module parameters
To utilize the CPU memory completely, you should use a memory card with more
memory capacity than the work memory of the CPU.
What is Stored on the Memory Card?
The memory card can store the following data:
•
User program, i.e., blocks (OBs, FBs, FCs, DBs)
•
Parameters that define the behavior of the CPU
•
Parameters that define the behavior of I/O modules
