[Swap Bytes Extended]

How are SD filename and type related with SWAP bytes? I understand from the FB name, it can be used to swap bytes from a tag.

[SAMBA HMI - TEXT OBJECTS INVISIBLE]

I had same behaviour once but with V400. I solved it updating OS, downloading an empty application and then downloading the application again.

[Float inverse]

I think you need swap bytes using B=32 bit or a series of swap functions.

 

[Load cell calibration]

I´ve never done this before, but I guess Edit Calibration Point can be used for your purpose. It may be located on FB|Loadcell|Advanced|Calibration menu.

 

[Jazz Display not working]

Check SB9. 

[Several controllers & 2 EX-RC1]

Do you expect having 3 Unistream panels acting as Masters of UniCAN network? I´m not sure it will be possible.

Is it possible for you to use a single Unistream to communicate with both EX-RC1 and exchange data over Ethernet with another two Unistream?

 

[Visilogic 9.8.31 Not Starting]

If you have only Visilogic software, you may try deleting all files in "C:\Program Files\Common Files\Unitronics" directory after uninstalling Visilogic. Then, install software again under administrator privilegies.

[V130 Master Jazz Slave via Ethernet]

Flex, I disagree. You can use one socket to communicate with several slaves, once at a time, off course. 

Nikola, slave ID must be 255

[Vision 120 comms to Epson LX-350 printer over RS232]

You may want to check if your printer has serial interface enabled and serial parameters properly set.

[keypad entry variables]

Check SB111. It must be set to disable touch keypad

[Modbus RTU and Danfoss]

You set PLC Master ID = 2 and also trying to read/write from/to slave ID=2.

Change master ID.

[Shift]

Having MI 0 = 512 then rotating 9 positions left, you will get MI 1 = 0

[PID Motion control]

Why do you need such PID response speed? As far as I remember, electro-pneumatic actuators are not so fast. You should consider your analog transmitter conversion time, PLC analog input conversion time, actuator response and process response time itself to set appropriate PID sample time.

 

[Volume Calculation]

Use SB15 instead of SB7 to get calculation only once per 100 ms

SB15 keeps ON during one single scan, SB7 keeps ON during 100 ms.

[Modbus TCP or Modbus RTU over TCP?]

Vision Enhanced such as V130 does support both Modbus TCP and Modbus RTU

[Load DTI From File issue]

As help file stated, you must wait at least 15 seconds.

 

[Move Members in a Struct]

Any update about this?

 

I need to reorder data inside struct used to Ethernet/IP adapter to match data sent by remote device.

[Filter FB]

I suggest you to place every FILTER CONFIG in a single net, also FILTER CALC.

I use direct contact of SB15 instead positive transition of SB7.

Make sure you don´t use filter 2 operands anywhere else in your code.

["No application" error]

Thanks all for reply.
The problem happened only once, two weeks ago.
The last change I've made, one month ago, didn't download all and burn, just download. However I keep a copy of application in SD which allow us to recover it.
There's a snap-in module attached.

 

The past weekend, I perform a brief maintenance to PLC: Cleaning, dust blowing, battery check, re-attach snap in, check power voltage, full clone to SD.

 

So far, everything OK

 

["No application" error]

Hello all,

PLC: V1210, OS 3.09.06

Yesterday I got a black display with "no application" error.

I restored it, selecting Application from SD Menu in INFO mode (Only application).

All information remain unchanged (Datatables and operands) and SB8 (Battery low) = 0.

 

 

¿What could cause it only application was lost and not datatables nor operands?

 

[Keyboard entry description field]

Instead, I would add a prompt field, which may be blank or whatever programmer decide.

Also in the popup window, would show automatically min and max values, so the operator knows the variable valid range.

[Remote Operator on PC works but Android version does not]

I have same situation. I can connect phone to PLC when both are connected to same LAN but not remotely exactly as Aus stated.

[Display Data table elements on HMI]

+1

 

I also would add edit data and sort option by desired column. Very useful when using recipes and data logging.

[Error 391]

I've got the same error several times with current project development including several images. I had to close Visilogic, re-open it and download again. It forces PLC to download entire images set instead of the ones I just changed.

[Timer not changing state...]

Cheers !!!
