IMPLEMENTING ALARM (LADDER) IN PLC

The following describe how to implement simple alarms in a PLC.
We used a MICRO PLC TSX3722 and a card
TSXDMZ28DR (16Inputs/12Outputs) but any PLC could be used.

Here is the electrical drawing

The implementation on the PLC is for each input . 2 Inputs used for this example.

The following images showing how to implement the HORN and the LIGHT signalling.

As the figures shows the auxiliarys bits are for the Horn indicator and the Alarm Inputs are for the LIGHT indicator. The programmer can also add as many alarms as he wish to this rungs either directly or as a sum of alarms. It is left to programmer how to achieve this, but consider the limitation of the rung when using a PLC like the MICRO As you could see there are 7 vertical and 11 horizontal positions. In the figures several inputs as alarms (errors - thermal relay etc) and auxiliaries added to demonstrate how to add more than 7 vertical contacts.

PUMPS CIRCULATION FOR FOUNTAINS APPLICATION

PUMPS CIRCULATION FOR FOUNTAINS

This is an application which consists of 3 pumps circulate per 2 a 4th filter pump and a 5th waste water pump for controlling a fountain. The application was developed with Zelio Logic SR2B201FU with real time Clock and Display capabilities.

MICRO TELEMECANIQUE P.L.C CONNECTION WITH PC THROUGH MODEMs - OLDER VERSION

ATTENTION TO THE READER
NOTE : THIS DOCUMENT IS MOST FOR EDUCATIONAL PURPOSE ONLY, AS THE APPLICATION WAS DEVELOPED WITH PRIOR VERSIONS OF MICRO - PL7 SOFTWARE AND WITH NO GENER MODEMS. THE RECOMMENDED CONNECTION IS THAT WITH GENER OR ETIC MODEMS OR ANY OTHER MODEM THAT SCHNEIDER ELECTRIC RECOMMEND. YOU COULD FIND THE APPLICATION WITH GENER MODEMS HERE AND THE APPLICATION WITH ETIC MODEMS HERE
The Application files make it possible to implement communications of telemaintenance
and dialogue inter PLCs

In this application 2 modems MultiTech Systems - Model MT2834ZDXle was used
For more information on the specific modem manuals of multitech
http://www.multitech.com//DOCUMENTS/manuals

The settings - The AT commands that modems must have are:

MODEM PLC

At the "Telephone Number" put the number you want to call which is connected with the remote PLC
Becareful if a telephone center exist.

With OK go back to the previous image, and select the menu

FILE -> ADVANCED CONFIGURATION having the following options.

CAUTION: To be connected via modems with PL7 V4.1 & V4.2 should have the following drivers:

UNI-TELWAY Win2000/98 V1.4 IE08

UNI-TELWAY WinNT4 V1.8 IE15

UNI-TELWAY Win95/Dos V7.8 IE18

UNI-TELWAY Dos V7.4 IE14

Also, the use of the modem in conjunction with Magelis terminals from the port TER - AUX is not possible because the Magelis not respond by changing the Parity to None, in which case their combined use is impossible. For the solution of this problem must be used a modem that has the ability to pass 11bits (8 data, 1start, 1stop, odd parity), so then you need to configure it according to instructions and commands given in the manual.

A Modem which has the above feature is that of the company GENER.

(Schneider Alliance) model GENindus

MAGELIS TERMINAL ADDITION IN UNITELWAY NETWORK TO A SLAVE PLC

Suppose we want to insert a Magelis terminal to a Slave PLC which is connected to a network Unitel-way. To the Slave PLC have given an address AD0, which is defined in the network. To be able to connect the Magelis at the Slave PLC, do the following: Select the Menu Configuration -> Equipment Symbols ... and get the following picture (Fig. 1),

Select Modify and displays the next image (Fig. 2) which will change the existing usual (0,254,0,254,0) which referred to the master PLC, and give one another Symbol name of your choice.

A simple network Unitel-way without PCMCIA card is not feasible to achieve the connection because the number of Slave PLCs is limited. The addition of two or more terminals Magelis consists networks using Unitel-way card PCMCIA RS485 (TSXSCP114) adjustable to 32 Stations (Magelis - PLC)

In addition the cable XBTZ968 which is used for the connection between Magelis and Slave PLC must be modified or added by a serial cable specially constructed taking in mind the Slave PLC address (it is recommended to constructed a serial cable to added to the existing XBTZ968)

Programming/animating Twido via existing RS485 bus.

Description:
- This document describes the possibility to connect Twidosoft to Twido on existing RS485 bus for programming or monitoring purposes using Modbus communication protocol. Primary (built-in) or additional RS485 communication adapter may be used.

Hardware
One or more Twido controllers (optionally with additional RS485 communication adapter installed.)
TSXPCX1031 serial programming cable Or TSXPCX3030 USB programming cable
mini-DIN female connector
Software
MS Windows XP SP1 / SP2
Twidosoft v3.2
Twido fw. 3.20

1. Tested configuration

You will need an adapter (mini-DIN to free wires) in order to connect TSXPCX 1031/3030 programming cable to screw terminal block.
Adapter wiring:

Create an adapter using spare mini DIN female connector.

Use pins 1, 2, 7 (data+, data-, GND). It’s necessary to connect external 5V DC power supply to pins 8 (5V) & 7 (GND) to supply the RS232<->RS485 converter inside the cable. It’s possible to use 5V from PS/2, USB or Twido’s mini DIN connector

Notes: -When connecting to Port 1, pins 5 (DPT) and 7 (0V - GND) must be interconnected, otherwise Twido sets the port for communication with Twidosoft (Address 1, 19200kb/s, no Parity) and ignores the user setting.

-Other modbus devices than Twido may also be present on the network.

2. Setting up connection in Twidosoft

You will need to modify the connection preferences: File – Preferences – Connections Management

Connection type: Serial for TSXPCX1031 serial programming cable
USB for TSXPCX3030 USB programming cable

IP / Phone: Corresponding COM or USB port
P-Unit / Address: @ - This setting lets you choose the address before every connection.
Baud rate, Parity, Stop Bits....: Use the exact setting of the network you wish to connect to.
Confirm the changes, select your connection from the drop-down menu and confirm again.

3. Connection

Set the rotary switch on programming cable into position 1 – OTHER MULTI.
Click on the connect button.
Select the address of PLC you want to connect to.
Confirm.

Note: The line must be silent while connected with Twidosoft. If there is any other communication, the connection will fail.
This connection is not suitable for firmware update (possible only through Port 1 with default comm. setting). Communication failure would result in a permanent damage to the controller

MONITOR PRO TAG COUNT CLARIFICATION

Hardware Standard PC
Software MS Windows XP SP2
Monitor Pro 7.2
Monitor Pro 7.6

MONITOR PRO 7.6

The total tag count can be found by right-clicking on the application in
Config Explorer, slide down to "View" and then open "Application Size".
This returns the total number of tags the app is configured for and the total
number of user defined tags.
The total tag count restriction on a Monitor Pro Server is based on the
user-defined tags. Schneider Electric defined global tags such as
SECTIME are not considered user defined tags are excluded from the total
user defined tag count limit.
e.g. If a customer has a 1024 total tag count license then he can have 1024
user defined tags.
I/O tags are defined by the number of tags entered in a device driver,
Ioxlator, or ECI table. It is not based on the number of registers addressed
in the PLC. For example, if you wants to read HREG 40001 into MyTag1
and into MyTag2, that counts as 2 I/O tags even though you are reading
from the same register in the PLC. In other words if the user defined 5 read
tables with 10 tags each in his netdtl driver table, then he has configured
50 I/O tags.

TWIDO with CANopen multi turn Encoder

This example describes configuration of Twido PLC with Osicoder XCC-3510PS84CB CANopen multi-turn absolute encoder.

Hardware Any Twido controller except
TWDLC•A1•DRF

TWDNCO1M CANopen master SV2.0
Osicoder XCC-3510PS84CB Absolute
CANopen encoder
Software Twidosoft 3.5
Windows XP SP2

1. Tested configuration

2. Features

XCC-3510PS84CB in default configuration sends information about actual position on reception of synchronisation message.
Twido CANopen master doesn’t support SYNC object. Therefore it’s necessary to switch XCC-3510PS84CB to send information about position cyclically. This is done by writing a value in milliseconds to 16bit object 6200h sub0 (Cyclic timer). That makes the encoder send position value with selected period ranging from 1 to 65535ms.Writing of Cyclic timer value is done via Service Data Object (SDO). It requires a communication table to be created in internal memory of Twido and then sent using CAN_CMDx command. It’s necessary to repeat this procedure after every power cycle of Twido and/or encoder.

CONNECTING PLC WITH GSM MODEM FOR ALARM ANNOUNCEMENT

ASSOCIATION PLC WITH GSM-MODEM

SMS MISSION FOR ERRORS REPORT

How can we have remotely, when an alarm happens, the report of the error in the installation?
Simply, by sending an SMS message alarm from PLC in our mobile.

Below we describe the logic and message sending, reporting an error.

The SmsAlarm.stx program shows us how can we send SMS and find errors. In this program we are able to recognize only three errors, for example. Of course we can identify more, and that depends on the application and severity of errors (Alarms). It is in the hands of each developer to create in the PLC a database-constants, which correspond to specific error-Alarms.

Also this example is not binding, except the codes to send in GSM - MODEM to send the SMS message. Thus it can be changed depending on the application except for certain items to be analyzed.

The application has been made on a series PLC MICRO TSX37. Communication with the GSM MODEM is through the cable programming TSXPCX1031 with the trimmer in option 3. We also need an additional cable, which you must build yourself, but it is very simple.
On the side of GSM - MODEM a male connector VGA 15-pin must be used, while on the side of the PLC, to connect the cable TSXPCX1031 must be used a male serial connector 9-pin, and the connections are:

9 – pin 15 – pin

5 <--> 9

3 <--> 6

2 <--> 2

So Simple

The GSM - MODEM that we have chosen is from the company WAVECOM
The model has code order WMOD2B - M1203A. For anyone interested in more information , on the Site Wavecom.com, can find the manual of the product.

The program distinguish two PRINT_CHAR commands.

In the first command

After selecting a channel in the PLC, (ADR # 0.0.SYS - From TER) the code AT + CMGS is the command necessary for the GSM - MODEM, to send SMS, while the numbers where are between " " is the number of mobile in which we send out the SMS. The Code $R (CR = 0D - Ascii Hex) is the Return.
The % MW120: 4 is the reference words for communication, which you can change.

NOTE: The channel selection (ADR # 0.0.SYS - From TER), the code, the phone number, and the code $R is absolutely binding and must be placed exactly as you can see them in the command.

In the second command, and after a delay of 500ms (TP = 500ms) as noted in the program

The %MB200: 20 is equivalent to %MW100: 10. In these words, placed as seen in the program, the initial commands (the command Operate), the constants describe the current message that we want to send. That we putting in %KWs the message we want to send (from the Application Browser select Variables--> Constants --> Words). Caution should be taken, each character must be written with the corresponding HEX code from the ASCII table. Something else to pay attention, is that we must engage a specific length of characters and must in the end of each message to devote a %MW to write the code 16#1A00, which is necessary to convey the message (close this message).

Also in the Hardware Configuration of the PLC in COMMs must be chosen for the Channel 0 "Character Mode" as shown in the program.

Care must be taken from the developer in every application the code used. It is the rensponsibility of the developer to use the code properly in his application

UNITELWAY NETWORK

UNITELWAY NETWORK

Suppose we want to exchange information between two PLCs via network UNITELWAY. The following figure (Fig.1) shows a circuit of both PLC. Two TSXPACC01 placed to protect the TER entrances of each PLC by exogenous risk factors (hypertension, overvoltage etc.) and are very necessary

Figure 1

At the following figure (Fig.2), we can see the configuration needed to addressing the 1st PLC
This picture listed for the Master PLC. To display the image below, do the following steps:
In the PL7 Application Browser, application has already created, select Configuration -->
Hardware Configuration.
The Hardware appears and double-click on the shape of the TER which is displayed below the image.
In option "select CHANNEL" select CHANNEL 0.
If PLC PCMCIA card is installed and we want to use it then select CHANNEL 1.
Next choose the type of communication that used, in this case UniTelWay.
Then choose the "Type" --> Type Master.
Below the latter option see this option "Number of slaves" = 8 indicating the number of Slave PLC, from 4 to 8 Addresses Slaves. (A PLC can have from 1 to 3 addresses depending on the application. The position 0 is bound by the Master CPU, and the 1,2,3 for a device programmer (eg PC) .

Figure 2

Whole can be connected up to 5 Slave PLC, but if you connect a Magelis terminal, then limited to 3 Slave PLCs, because Magelis binds 2 Addresses.
If you use PCMCIA card then the total number of Slave addresses is about 98.
Below we see Figure 3, which refers to the Slave PLC.
We make the same adjustments but also set the option "Server Address AD0" to 6.
It is best to begin the addressing of PLCs by this specific address (if other used).
We can introduce a Magelis terminal to the existing network.
In this example we will follow the specified address and we will see how to put together the basic commands for data exchange.

Figure 3

The following figure (Fig.4) shows the commands necessary to achieve communication between the PLC network UNITEL-WAY

Figure 4

Suppose you want to read three words from the Slave PLC using the command
READ_VAR (ADR # 0.0.6, '% MW', 1,3,% MW10: 3,% MW200: 4)

ADR # 0.0.6: the destination address (Slave PLC), Module = 0, Channel = 0, Ad0 = 6

'% MW': is the type of data (internal words)

1:% MW1 is the Slave PLC 1st % MW

3 is the total number of words to be read from the Slave PLC

So you read the following 3 words - % MW1,% MW2,% MW3.

%MW10: 3: is the area in the Master PLC to place the above three words
i.e positions % MW10,% MW11,% MW12, respectively.

%MW200: 4: activity bit, report, length.

Now suppose that we want to write three words to Slave PLC using the command
WRITE_VAR (ADR # 0.0.6, '% MW', 20,3,% MW30: 3,% MW250: 4)

ADR # 0.0.6: the destination address (Slave PLC), Module = 0, Channel = 0, AD0 = 6

'%MW': is the type of data (internal words)

20 means the %MW20 the Slave PLC 20th % MW

3 is the total number of words will be written to the Slave PLC

So you write the following 3 words % MW20,% MW21,% MW22.

% MW30: 3: is the area in the Master PLC from where they would write the above three words in the Slave PLC, ie positions% MW30,% MW31,% MW32, respectively.

% MW250: 4: activity bit, report, length.

MASTER - SLAVE

READ

% MW10: 3 <-- % MW1: 3

WRITE

% MW30: 3 -- > % MW20: 3

In Figure 7 we see how to connect the cable at the interior connectors of the
TSXPACC01, and at figure 8 the communication connectors of the TSX P ACC01

Summary:

This is an example of how to use the READ_VAR and WRITE_VAR commands and also how to configure the PLCs to form a UNITELWAY network. This code should be altered or inserted respectively in your specific application. It is your rensponsibility to use the example properly in your applications

USE OF INCREMENTAL ENCODER WITH INTEGRATED COUNTER AT CHANNEL 11.

At following figure 1 is the connection of the P.L.C with TELEFAST 2

Figure 1

Figure 2

At our example we used P.L.C Micro TSX3722 and encoder XCC1510PR01K
with 11-30V/push-pull/100cpt

In Fig. 2 connection with the sensors, which is similar with those of the ENCODER
Cables and color of encoder and TELEFAST 2

RED = 24Vdc - 26
BLACK = 0V - 27
GREEN = Α - 4
BROWN = Α - 1
YELLOW = Β - 8
ORANGE = Β - 10
And we connect the Α-, Β-, και 0V together. Ζ and Preset are Not Connected.

The small program is analysed
The small code program named INCOUNTERUPDOWN.STX and you could download it HERE
We use two Setpoints (High & Low). When passed from High setpoint an output is activated %Q2.1. Then when the rotation of the movement will inversed, then passing through Low setpoint another output will be activated %Q2.0, and finally when under 15 steps ouputs are zeroing.
We used %MD0 for the Highsetpoint and %MD2 for Lowsetpoint which are give values at the following

%MD0=%MD0.11.10 Value of High Setpoint
%MD2=%MD0.11.12 Value of Low Setpoint όπου
0 = Module
11 = Counter0

Making Enable the Counter setting the %Q0.11 with a contact %Ι1.4

Making Preset the Counter setting the %Q0.11.1 with a contact π.χ %Ι1.7

Making Reset Preset τthe Counter setting the %Q0.11:X1

With %I0.11.9 we know every momment the direction of movement of the Εncoder.

%I0.11.7 (Current Value >Highsetpoint) Encoder Value has passed the Highsetpoint

%I0.11.8 (Current Value>Lowsetpoint). Encoder Value has passed the Lowsetpoint

Finally with WRITE_PARAM %CH0.11 we could change the High and Low setpoints giving values at %MD0 & %MD2.

In the following figure 3 is the Hardware Configuration of the PLC Internal Counter.

3. Summary

This procedure can be used to get values from/to Twido PLC. Manipulation with a table in spreadsheet is more convenient than manual modification of animation table in Twidosoft/Twidosuite..
Length of animation table is restricted to 64 rows. It’s possible to have multiple animation tables in Twidosuite. Trying to write retained values to objects that are not writable will result in a non-critical error.\
