Programming Devices and Formats

Programs for the Micro PLC can be created using a computer that is equipped with the programming software, or using a Hand-held Programmer.

Programming with the Programming Software

Programs created with the programming software are in traditional ladder logic format:

I0001		O0030

46011

I0002	I0003			C0001

C0001

Chapter 2 describes programming with the programming software.

Programming on a Hand-held Programmer

Equivalent programs are easily created on the Hand-held Programmer. For example:

Key Operations

HHP Displays

START

I

1

ENTER

STA I001

Empty location

OUT

O

3

0

ENTER

OUT O030

Empty location

START

I

2

ENTER

STA I002

Empty location

OR

C

1

ENTER

OR C0001

Empty location

AND

F3

I

3

ENTER

AND NOT I003

Empty location

OUT

C

1

ENTER

OUT C0001

Empty location

Chapter 3 describes programming with a Hand-held Programmer.
