I/O Addressing
Each terminal on a Field Wiring Arm is identified by a 5-digit address
(Figure 2.8). The 5 digits in the terminal address directly correspond to a
memory location in the Processor’s Data Table and designate the following:
The first digit is either a 0 for outputs or a 1 for inputs.
The second digit refers to the Rack Number (always 1 for the Mini-PLC-2/15
System).
The third digit refers to the Module Group Number (0-7). A Module Group
consists of two adjacent I/O Module slots in the I/O Chassis starting at the
left (Figure 2.9). The Module Group Numbers for each pair of I/O slots are
identified on labels on the Chassis latches.
The fourth and fifth digits of the address refer to the Terminal number within
the Module Group (00-07, 10-17).
