System Overview
Overview
Pico is an electronic control relay with built-in logic, timer, counter, and real-time
clock functions. Pico is a control and input device rolled into one that can perform
many different tasks in building and machine applications.
Pico is programmed using ladder diagrams, and each programming element is
entered directly via the Pico display. For example, you can:
• Connect make and break contacts in series and in parallel
• Connect output relays and markers
• Define outputs as relays, flip-flop relays or latching relays
• Select timing relays with different functions
• Assign eight up and down counters
• Display text with variables (1760-L18AWA only)
• Track the flow of current in the program
• Load, save and password-protect programs
Most controllers also offer a real-time clock, allowing up to 32 separate on and off
times.
The dc versions can receive analog signals at two inputs and evaluate the signals
with eight analog comparators.
If you prefer to program Pico from a PC, use PicoSoft programming software.
PicoSoft allows you to create and test your programs on the PC. It also enables you
to print out your programs in DIN, ANSI or Pico format.
