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 5 we see the internal view of TSXPACC01

S1: Selector of how the PLC (Master or Slave) which is attached the TSXPACC01
S2: Selector finish line BUS.
JA and JB: connectors TSXCSA 100/200/500 cable of the BUS.

Figure 6

Specific configuration options in our example.
For the Master PLC: S1 place in OFF postion and S2 in the NOT OFF.
For the Slave PLC: S1 = NOT OFF, S2 = NOT OFF.

Figure 7

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

Figure 8

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

MICRO TSX37

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.

Figure 3

Use of the Incremental encoder is only applied at Counter0 (CNT1 – CHANNEL 11)

How to import and export user data to/from Twido PLC

Title: How to import and export user data to/from Twido PLC

Description:
- This paper describes a workaround that allows exporting and importing user memory data from/to Twido controller using Twidosoft/Twidosuite animation table editor and an external spreadsheet with XML support.

Hardware any Twido controller
Software Twidosoft 3.5 or Twidosuite 1.2
MS Excel (tested with Excel 2003 SP2)  

1. Export of data

1.1. In your application create an animation table containing addresses you want to export values from.

1.2. Copy current values to retained

Twidosoft:
 

Twidosuite:
 
 

 
Figure 1: Copy current values to retained
 
1.3. Save/export your animation table to disk

Figure 2: Saving *.tat animation table file to disk

1.4. Open the *.tat file in MS Excel as XML list

Figure 3: opening of the animation table file in MS Excel

1.5. The file is displayed in Excel in form of a table, very similar to animation table in Twidosoft/Twidosuite

Figure 4: Data exported from Twido PLC displayed in Excel
 
2. Import of data


2.1. Go through steps 1.1, 1.3, 1.4 and 1.5.

2.2. Modify values in “RetainedValue” column of the table.

2.3. Save the file as XML data to keep the structure of your file

Figure 5: Saving of modified animation table

2.4. Rename the file from *.xml to *.tat

2.5. Open/import the modified animation table in Twidosoft/Twidosuite

Figure 6: loading/import of animation table
 
2.6. Use the button to copy retained values to current values

Figure 7: copying retained values to current values

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.\
