Introduction

Installation of the Auxiliary Function (AF) PROM (cat. no. 1772-AF1) in your
Mini-PLC-2/15 controller lets you expand its mathematical capabilities.

For simplification, throughout this manual we refer to the Auxiliary Function
PROM (cat. no. 1772-AF1) as the AF1.

The AF1 can only be used with the series A Mini-PLC-2/15 processor module,
firmware revision 11 or later (cat. no. 1772-LV). The AF4 can only be used
with the series B Mini-PLC-2/15 processor module, firmware revision 4 or later.
Programming the AF1 functions with either series Mini-PLC-2/15 processor
module requires the Industrial Terminal (cat. no. 1770-T3).

The AF1 has a 2K (16 bit) word section to which you can transfer your program
(for backup memory) and a 2K word section for higher mathematical functions.
you can only transfer your program into the AF1 with the series B PLC-2/15
controller (Table 1.A). Series A Mini-PLC-2/15 Processor EPROM (publication
1770-915) describes program transfer to PROM. With the series A PLC-2/15
controller, program transfer to the AF1 is not possible.

You can erase the 2K memory backup portion of the AF1 with ultraviolet light. However, the

2K section for higher mathematical functions would also be erased and all AF1 function

capabilities lost. Once erased, the AF1 functions are irretrievable.

NOTE: The AF1 is sensitive to ultraviolet light, therefor when exposed to uv
light, both the program and the auxiliary functions are erased. The AF1’s
transparent window is covered with the product label to avoid accidental
alternation of memory from uv light sources. Do not remove this label.
