FOREWORD The project E-Laboratory Practical Teaching for Applied Engineering Sciences
(Acronym EPRAS) is implemented under the Hungary-Romania Cross-Border Co-operation
Programme 2007-2013 (www.huro-cbc.eu), and is part-financed by the European Union through
the European Regional Development Fund, Hungary and Romania. The programme aims to
bring the different actors – people, economic actors and communities – closer to each other, in
order to better exploit opportunities offered by the joint development of the border area.
This material contains the documentation associated to the e-laboratories designed by the
project team from University of Debrecen in the frame of this project.

Industrial process control with Twido PLC
Theoretical background
1. Bases of the program:
The ladder programming language most commonly used PLC programming tool. The
electrical model developed road plans, they are regarded as equivalent to the software, but
today's PLC systems developer traditional relay logic corresponding elements already too
many complex organizational functions and program analysis techniques allow the use of
ladder programs within
1.1 Basic elements
The Ladder of the following basic elements:
line
contact
coils
function blocks
1.1.1Wires
The graphical representation of the left hand side is positive tápsín vertically on the right side
and negative power supply rails. Between the two horizontal and one below the other current
paths. Each current path on the left are the contacts, the right-hand side of the coils. A current
path (Rung, Network) is a Boolean function implements. The serial or parallel connection
contacts of the AND and OR logic elements to deliver on our relationship. The coil is stored
in the logical result of a function. The Twido PLC in today's PLCs, like most of the logical
functions from top to bottom, a function (ladder line) and within calculates from left to right.
Figure 1 logical function
The (Fig. 1) is: Q = ((A and B) or C) and (not (D)) to implement logic functions. The "A",
"B", "C", "D" may be the binary inputs of the PLC, the "Q" is one of the two-state output, but
there may be internal memory variables. (The above statement, the parentheses in the not (D)
exception is not necessary.)
1.1.2 Function Blocks
This brief summary of today's PLC is located in a number of function blocks, only
measurement is required and the Twido PLC can be used in the main function blocks
shows.timers
The Twido PLC units, operating in three different timer can be used:

Counters.
CU in the counter input rising edge of the counter is increased by 1, the CD input is in a rising
edge is reduced. The R input in logic clears the counter value is TRUE, TRUE value in the S
input and set the value of Preset Value. The counter block compares the current value is
always known. Value preset value, and consistency, the D (Done) logic output is set to TRUE.
The Twido PLC counters can count the 0th .9999 range. Greater numbers of two or more
counters count kaszkádosításával solved. E and F of this output can be used in the bottom
(Empty) or overflow (Full) show (Figure 3)
Figure 3 Counters
Comparator block
The "C" coil is activated when the "A" and "B" contacts are closed, as well as in the previous
example of the counter value is less than 5. The comparator block the usual relational signals
can be used: >> = << == <> Analog input signals when processing the operands can be such a
comparator.: IW0.0%,% MW0

Arithmetic block
The physical address% MW1000 select the maximum amount of memory. The arithmetic
blocks on the right side of assignment expressions consist of the usual arithmetic operation
symbols + - * /
Analog output signal produced at the left for example, in QW1.0%, +10% MW1.
Figure 5 Arithmetic block
2. Addresses used in programs
The Twido SUITE in the variables (input, output, memory, ...) to address we have. The form
of the following addresses:
Ix.y%:% IWx.y Two state input:
Analog Input
QWx.y%:% Qx.y Analog Output:
Two state output
TMX%:% Mx Timer:
Memory Bit
% Cx: Counter% MWx:
Memory word
3. Symbolic variables
The variables and objects used by the program (timers, counters, etc) should be given
symbolic names and physical addresses instead of the Ladder of contact for them to use. The
program is so readable, easier to understand. The symbols and the physical address mappings
of the Twido Suite-_ Configure menu item can be done. Symbolic names can not contain a
space character, not start with numbers, but you can use accented characters.
4. Subrutin calling
If the programming you want to create junctions, the main program must be taken in the
program. The main program can be selected which do it contains logical and / or function
block instructions. A (Fig. 6) (Figure 7) in the sample program.

Remote flow control
Theoretical background
The measurement name: FluidLab
The test site: University of Debrecen, Faculty of Engineering, Department of Electrical
Engineering and Mechatronics
Measurement Objective: Flow Control and control remotely
Measuring accessibility: http://epras.webhost.uoradea.ro/
Description of the measurement:
To carry out this exercise the knowledge of computer's basic handling is essential. By
performing the measurement trainees could implement control technique and regulate
processes under real conditions. The results of interventions remotely can be traced on an
operating model that appears on the user's own computer (Figure 2) and by the help of the
image of a web camera.
In case of remote operation the fluid flow could be controlled by a mixer and two pumps.
During the control it is possible to measure, monitor the heating and cooling temperature
curve of the water in the tank. The control loop time constants could be calculated from the
resulting characteristics. Using the specified time constants one can set the classic PID control
parameters. The effect of the calculated control parameters can be tested using the station.
If necessary, the results can be further refined.
