[Boolean to HMI]

Hello,

Basically you can first use Bit to Num ladder element to store the inputs array into a integer register.

Then write the value of the register to the data table.

Now in the data table you can right click on the cell of the integer column - select format:

Then choose Binary:

Now your column will be shown as Binary format on the HMI.

[EX-RC1 configuration]

Hello,

I just wanted to add that there is a video tutorial that explains how to use EX-RC1 with UniStream:

 

[DHCP Connection]

Hello,

Currently UniStream does not support DHCP – You need to set static IP address.

Please note that if IP address of a unit will be changed –the operator will not be able to know the new IP address of the Unit.

[Real number byte order]

Hello,

If when the system reads the Real number you are not getting the correct value , you can swap the bytes  to other register and then link this register to the MODBUS.

you can find the swap ladder element in Logic menu:

[An invitation to suggest ideas for new UDFB's]

Hello Swervomotor,

We added your request to the list. We hope that in the next release the option of duplicating a tag in a Struct will be available.

[FTP client won't connect to UniStream FTP server]

Hello,
We are not familiar with such issue.
Which firmware version is installed on UniStream? Did you try to cycle power the UniStream? If after power cycle it still cannot connect then send a mail to support@unitronics.com with the application and we will try to test it here.

[Modem Timeout error]

Hi,

First check that your signal quality is more than 14.

Also you need to check that the IP address and port you are trying to access are available - you can use a PC which is in the internet and try to access this IP and port via telnet.

 

[Reliable modbus supervisor PLC]

V130 has a built-in serial port that support RS232/RS485.  (The selection is done via jumper)

[Problem connecting with a V1210]

Hi,

The ldb file is a kind of a data base file of the project - you dont need to use. when you close DataXport this file should disappear.

When running DataXport - what is the message you get in the log window?

 

[Timer preset using a variable]

Hi,

You will need to take care to mark the timer as retained. (You can do it from the Timers tab)

[Timer preset using a variable]

Hi,

if you wish to enter a new value to a timer on the screen, you can use the Timer box element and not Numeric box.

You can determine the format of the timer and then when the operator touch the timer it will open a keypad to enter the value and will show the format of each field.

["Drag and Drop" elements to Email body]

There is way to send indirect text as body of a mail message .

It requires some ladder logic.

There is a function called append buffer to user file that appends a buffer to a TXT/CSV/BIN file.

You can use copy tag to buffer first and then using the append buffer to file , you are basically creating a file with the tag data. (you can also use the message composer to create messages and then use Build message to put it in a buffer).

This buffer is the one you will append to the user file. The file needs to be TXT.

In the e-mail configuration you will click on attachment an select the file with the text you wish to send and then the option send as body.

 

The file will not be as attachment but its content will be in the body of the mail.

 

 

[Program stuck in "Alarm Manager"]

Hi,

Are you referring to the Alarm Summary ?

How are you calling the Alarm Summary display? (using action or from the banner)

Please send a mail to support@unitronics.com including the application and we will test it.

[Automatic backup SW]

Hi,

If you are using the Enhanced Vision PLCs then basically it comprises SD/Micro SD card slot.

The ladder offer a utility to clone the PLC (program, data tables, operand values) to a file. You can trigger this utility using a schedule or other method.

You can find this utility under Ladder --> SD menu --> clone

[PID struct retain]

Hi,

PID Config struct is non retained. Running PID  will use PID Config struct.

Once completing Autotune or manual tune, you can use the Save PID Autotune data ladder element. This will save the PID config struct to a PID AT params struct.

Then on power up you can use the Ladder element Load PID Autotune data from PID AT params struct to PID config struct.

Please make sure that the PID AT Params struct is checked as retained.

[brightness and contrast setting]

Hi,

You can change the backlight intensity using system integer 9. The values is between 0 -100.

0 - off

100 - full

[V570 SD cards , Data tables to EXCEL (need example)]

Hi,

You can save data table to a file using the ladder element save DT to SD. This will save the data table in UDT format.

Then if you wish to edit this data in your PC , you can use the SD card suite --> UDT editor.

When done you can copy the UDT file back to the SD and then using the ladder element Read UDT from SD to DT you can load the file back to the data table. 

[Downloading a project to V570]

Hi,

As you can see in the message you wrote " it is recommended.." - it will not initialize it after download automatically.

[PWM outputs opperate differetly]

Hi,

Please check the frequency.

I'm not near my PC now but if I'm not wrong the units of the frequency when using V260 is 1Hz and when using the V560 is 0.1Hz. 

[Count push button]

Hi,

First of all use positive transition when using the keys operands in order to get a single press. 

Can you specify what exactly is not working?

I noticed in the logic for example for key#1 that you are activating outputs according to the screen which is loaded. (I didn't see any counters)

[PID struct retain]

Hi,

For PID there are 2 structs:

PID Config - This is non retained struct which will be used for running the PID.

PID AT Parmas - This struct can be marked as retained.

Once you completed your manual tune or autotune, you need to use the Ladder element "save PID Autotune data" from the PID Config  struct to the PID AT Parmas struct.- This will save the PID data into the retained struct.

On power up you will use the ladder element "Load PID autotune data" from the PID AT Parmas struct to the PID Config  struct.

[Thermal Printer for a V130]

Hi,

According to our experience Zebra printers are ASCII based languages, so the FB protocol would work for implementing the communication.  We know already that customers are using applications with zebra printers before.

Attached is old example I found so you need to test it and implement the formatting according to your model.

[Visilogic 9.8.31 Not Starting]

Hi,

As I understand every time you try to open VisiLogic you get this error message. As Flex mentioned first backup your project file .

Then try the  follwing:

1.      Open Task manager and if VisiLogic process is still running  - End it.

2.       Open C:\Program Files (x86)\Unitronics\Unitronics VisiLogic_C\Data\DB

3.       Delete the file Current_OPLC.udb

4.       Try to open VisiLogic

 

[communication b/w PLc V1040 and raspberry pi]

Hi,

Do you wish to communicate between the Raspberry and the V1040 using communication (TCP) or IO?

If you wish to use communication you can use FB protocol IP (structure your messages ) or TCP_RAW Send & Receive.

In case you wish to use IO let me know the IO specification of the Raspberry.

[CanOpen variables]

Hi,

You can use Map register bytes. (You can find this element under CANopen menu).

Using this element you can set a source vector of MIs and assign & map different operands types to this vector.
