This manual is
intended to aid trained and competent personnel in the installation of
this equipment as
defined by the European directives for machinery, low voltage and
EMC. Only a
technician or engineer trained in the local and national electrical
standards should
perform tasks associated with the electrical wiring of M90 controllers.
Symbols are used to
highlight information relating to the user’s personal safety and
protection of the
equipment throughout this manual.
When any of the
following symbols appear, the associated information must be read
carefully and
understood fully.

Chapter 1: Overview
Introducing the M90 Micro
OPLC
The M90 is a micro
OPLC1; a compact
controller that contains a fully integrated
operating panel. It
is a fine device for simple control tasks, both household and
industrial. The M90
comes in different models offering a variety of capabilities,
including analog
control, CANbus and expansion ports. These M90 features give it the
flexibility to
control both time and ambient condition based processes.
Figure 1. The M90
The operating panel
shown in Figure 1 provides the operator interface. The M90
operating panel
contains an LCD text display screen and a keypad. The LCD screen
can be used to
display operating instructions, a feature that makes the M90 very easy to
use. The operator
uses the keypad to communicate information to the M90 or to
modify existing data.
This communication interface between the M90 and operator is
referred to as the
HMI, or Human Machine Interface, throughout this manual.
The M90 operating
panel offers an additional feature called Information Mode.
Information Mode
allows the operator to view certain types of system data such as
input status or timer
values.
The M90 web site can
be found at www.unitronic.com/m90/index.htm. Check this site
frequently for
product updates, new M90 applications and programming tips.

How PLCs Work
Figure 18 shows the PLC cycle. This
cycle is called a scan. The scan cycle is
performed continuously.
1
Reads data from inputs
2
Processes data according to
program
3
Sends data to outputs
Figure 18. PLC Scan
First, the input data is read at
the beginning of each scan. The data has two sources: the
M90’s physical inputs, and data
that are entered via the M90’s keypad.
Next, the program is executed. The
user creates the M90 control program. The program
is composed of instructions that
are written in the Ladder language, and is written using
the M90’s proprietary software.
All program instructions are executed in each scan
cycle.
Last, the outputs are updated
with the new data.
Appendix C: New PLC Users
63
The sample program below causes
an alarm, connected to output #1, to actuate
whenever a gate, connected to
input #1, opens.
The command means that the status
of the gate is checked at the beginning of each
scan. When the gate is open, the
value in the operand is 1 or on. When the gate is
closed, the value in the operand
is 0 or off.
The command controls the alarm. When
the value in contact 1 is found to be 1,
the alarm is switched on. When
the value is 0, the alarm switches off.
