460 MicroLogix 1100 Memory Usage and Instruction Execution Time
MicroLogix 1100 Indirect Addressing
The following sections describe how indirect addressing affects the
execution time of instructions in the MicroLogix 1100 processor. The
timing for an indirect address is affected by the form of the indirect
address.
For the address forms in the following table, you can interchange the
following file types:
• Input (I) and Output (O)
• Bit (B), Integer (N)
• Timer (T), Counter (C), and Control (R)
