When FFL and FFU instructions are paired, they must have different control addresses.
FFL and FFU Instructions
FFL (FIFO Load) and FFU (FIFO Unload) are instructions used in programming PLCs for managing data in a First-In-First-Out (FIFO) manner.
Control Addresses
Specific locations in memory allocated for the storage and manipulation of control functions within a PLC or other control system.
- Explain the procedure and impact of inserting logical terms into FIFO queues via particular directives.

Final Answer :
False
Explanation :
FFL (Fetch First Level) and FFU (Fetch Following Unconditional) instructions are part of IBM's mainframe instruction set, and there is no inherent requirement for them to have different control addresses. Their usage is determined by the specific needs of the program being executed, not by a rule regarding control addresses.
