Glossary
The following terms are used throughout this manual. Refer to the Allen-Bradley
Industrial Automation Glossary, Publication Number AG-7.1, for a complete guide
to Allen-Bradley technical terms.
Analog input
Analog inputAnalog input
Analog input - The DC versions of Pico have analog inputs I7 and I8. The input
voltage range is 0 V to 10 V. Input data is evaluated by built-in analog comparator
function relays.
Circuit connections
Circuit connectionsCircuit connections
Circuit connections - Every line in the circuit diagram display represents a circuit
connection.
Circuit diagram elements
Circuit diagram elementsCircuit diagram elements
Circuit diagram elements - As in conventional wiring, the circuit diagram is made
up of circuit elements. These include input, output and marker relays, plus
function relays and the P buttons.
Connect mode
Connect modeConnect mode
Connect mode - Connect mode is used to wire up the circuit elements in your
Pico circuit diagram.
Contact behavior
Contact behaviorContact behavior
Contact behavior - The contact behavior of any circuit element can be defined as
either a break contact or a make contact. Break contact elements are identified by a
line on top of the identifier (Exception: conditional jumps).
Entry mode
Entry modeEntry mode
Entry mode - Entry mode is used to input or modify values when creating circuit
diagrams or setting parameters, for example.
Flip-flop relay
Flip-flop relay Flip-flop relay
Flip-flop relay - An impulse relay is a relay which changes its switching state and
stays changed (latched) when a voltage is applied to the relay coil for a short time.
Function relay type
Function relay typeFunction relay type
Function relay type - Function relays are provided for more complex switching
tasks. Pico features the following types of relay:
• Timing relays
• Time switches
• Counters
• Analog comparators
• Text marker relays
Input
InputInput
Input - The inputs are used to connect up external contacts. In the circuit diagram,
inputs are evaluated via contacts I1 to I12. Pico 24V dc units can also receive
analog data via inputs I7 and I8.
Interface
InterfaceInterface
Interface - The Pico interface is used to exchange and save circuit diagrams to a
memory card or PC. Each memory card contains one circuit diagram and its
associated Pico settings. The PicoSoft PC software allows you to control Pico from
your PC which is connected using the 1760-CBL-PM02 cable.
Memory Module
Memory ModuleMemory Module
Memory Module - The memory module is used to store your Pico circuit
diagram, together with its parameter and Pico settings. Your data on the memory
module will be retained, even if the power supply fails or is switched off. The
memory module is inserted into the interface slot on the Pico device.
