Important User Information
Solid state equipment has operational characteristics differing from those of
electromechanical equipment. Safety Guidelines for the Application,
Installation and Maintenance of Solid State Controls (Publication SGI-1.1
available from your local Rockwell Automation sales office or online at
http://www.ab.com/manuals/gi) describes some important differences
between solid state equipment and hard-wired electromechanical devices.
Because of this difference, and also because of the wide variety of uses for
solid state equipment, all persons responsible for applying this equipment
must satisfy themselves that each intended application of this equipment is
acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for
indirect or consequential damages resulting from the use or application of
this equipment.
The examples and diagrams in this manual are included solely for illustrative
purposes. Because of the many variables and requirements associated with
any particular installation, Rockwell Automation, Inc. cannot assume
responsibility or liability for actual use based on the examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to
use of information, circuits, equipment, or software described in this manual.
Reproduction of the contents of this manual, in whole or in part, without

Safety Information
ATTENTION
Electrical Shock Hazard
The electrical installation and commissioning work
must only be carried out by suitably qualified
personnel.
Do not work on the device when the power is turned
on.
Observe the relevant safety regulations:
• Turn off the power
• Make sure that the device cannot be powered on
again inadvertently
• Check to make sure that no dangerous voltages
are present before working on the device
Simply Pico
Clever Switching and Controlling
Pico is a compact, user-friendly and low-cost controller for simple
control applications. Applications range from building and domestic
automation to machine and plant control. Pico has built-in
user-friendly operating elements and an LCD display.
Connect Pico and draw a circuit diagram on the display by pressing
the buttons on the device. Pico works with make contacts, break
contacts, and relays.
Enter a circuit diagram in Pico just like it is sketched on paper. Pico
has basic and advanced functions for relays, time switches and
contactors, among other functions. Make changes to the circuit by
pressing the buttons on the device. Time consuming rewiring is not
necessary.

Power Up Pico for the First Time
TIP
A brief current surge is produced when powering on
the unit for the first time. Do not switch the unit
using reed contacts, since these may burn or melt.
When you power-up Pico for the first time, you are asked to select the
menu language.
Use the up and down cursor buttons to select a language. Definitions
of the language abbreviations are shown below.

Analog Comparator
Available functions:
• I7 ≥ I8, I7 ≤I8
• I7 ≥ Setpoint, I7 ≤Setpoint
• I8 ≥ Setpoint, I8 ≤Setpoint
The analog comparator can compare voltages from 0V to 10V
(setpoints “0.0” to “10.0”).
Analog signals of sensors typically fluctuate by
several millivolts. For stable switching the setpoints
should differ by at least 0.2V (switching hysteresis).
Do not use any relay with output energize or
impulse relay coil functions.

Pico Interface Socket
The Pico interface socket, which is beneath a protective cap, accepts
the optional Pico memory module, or connects Pico to a PC using the
optional PC interface cable and the PicoSoft software. This allows you
to copy the circuit diagrams to and from the PC and/or memory
module.
Memory Module
Memory modules are available as an optional accessory. Each memory
module can store a single Pico circuit diagram. Information stored on
the memory module is non-volatile (the information is not lost when
the power is turned off). The memory module can be used to make a
backup copy of a program and/or to transfer it to another Pico
controller.
Each memory module can hold one Pico program, up to 32K.
Each memory module stores:
• the circuit diagram
• all parameter settings of the circuit diagram
• system settings
1760-MM1 for all 1760-L12xxx
controllers

1760-MM2 for the 1760-L18xxx
controllers

ATTENTION
ELECTRICAL SHOCK HAZARD
The memory module and PC-cable socket are at the
potential of L2. There is a danger of electric shock if
L2 is not grounded. Do not make contact with
electrical components under the socket cover.
Load or Store the Circuit Diagram
You can only transfer the program from Pico to the memory module
or vice versa in the STOP mode.

parameter settings from Pico to the memory
module.

1760-L12xxx
1760-MM1 (Series A only)
1760-L18xxx
1760-MM2 (Series A only)
Series B Pico Controllers
1760-MM2B
Programs including all relevant data can be transferred from the
1760-MM2B memory module to the Series B Pico Controllers. The
existing 1760-MM1 and 1760-MM2 memory modules are Read-Only
when used with Series B Pico Controllers. The 1760-MM2B memory
module will not work with Series A Pico Controllers.

PicoSoft
PicoSoft is an optional PC program that creates, stores, and manages
Pico circuit diagrams. It transfers the circuit diagrams from the PC to
Pico or vice versa using a special PC interface cable.
ATTENTION
The PC interface cable is catalog number
1760-CBL-PM02 and is available as an accessory
item. Only use the Pico interface cable. Do not
attempt to make your own cable as this can cause
damage to the unit or present a shock hazard.
The PicoSoft software also includes extensive on-line Help.
To use the on-line Help, start PicoSoft and choose Contents in the
Help menu. Context sensitive help is also available. Choose a menu
item with the mouse and press F1 while keeping the mouse button
pressed.
Software Compatibility
If you are using programming software to program the Pico controller,
be sure that you are using the correct software version.
IMPORTANT
PicoSoft version 6.1 or higher must be used to for the
Series B Pico controller. Earlier versions of PicoSoft
can only be used with Series A Pico controllers.
Find the Series Letter
The Series letter is printed on the side of the housing as shown.
Download the Software
You can download a free copy of PicoSoft version 6.1 from our web
site. Go to http://www.ab.com/picosoft6.
For PicoSoft Pro, please contact your Allen-Bradley Distributor or
Rockwell Automation representative.
