[Starnge Memory Filling]

I update to V9.0.1 ans latest V570 OS and the problem disappear.

Thanks Jas

[Starnge Memory Filling]

Hye all,

I've got a very strange bug today.

I'm using a serial connection (RS232) which come from a PC to my V570 port 1.

I use Visilogic 8.9.5.

I have a message which is 89 bytes long using this format :

[sTX] ,NumVar1[1], NumVar2[5], etc ... , stream_1[7], stream_2[7],[ETX] [EOT]

The two last streams variables are stored to MI 2000 -> MI 2006, and MI2010 -> MI2016 using the option convert 1 byte received to 1 linked element.

If i uncheck the parameter Fixed Stream length in the protocol scan Setting for the streams variables and if the message doesn't contain streams the PLc receive, translate all the numerical variables but it 'fill a large amount of MI with strange values From MI 0 to MI 200 and a part within MI 1900.

If i check the parameter Fixed Stream length no problem, the Protocol Scan FB ignore the message because it don't have the good size

My question is : Why my Operand zone is filled with strange values ?

If someone had experienced a similar problem i'll be pleased to understand.

[coma separator problem]

Thx for reply Stein,

1) Decimal system separator = ","

i tried to change the excel separator as "." but nothing changed.

Ex : I've got MF10 = 40.7437 and MF11 = 40.42034 before exporting them.

After Importing into PLc, values are MF11 = 4.07E5 and MF11 = 4.04E6 ??

2) Decimal system separator "." and everything is OK !

All decimal values are exported and imported correctly !!

[coma separator problem]

Hye all,

I'm in trouble with the decimal separator.

I'm using RemoteAccess 9.0.1 on Windows 7.

I read some operands Values the export them into excel file. It seems that the MF decimal point disappear.

When i open Excel 2007 and import the File previously generated with RemoteAccess, all the decimal separator has disappeared.

The only way i founded is to change the separator type on windows Control Pannel as a point instead of a coma (We are in France)

This is not convenient, i don't want to change our customers system setting like this one.

Maybe i'm wrong but i think remote access don't use comma as decimal separator but as object/cell separator.

Is there another way ? or an option in Remote access to use comma as decimal separator ?

Thank you

Thank you Ash, And Merry christmas to all of you :-))

Hy David,

Here is an idea

[Visilogic Serial com Trouble]

Thanks Joe for the info,

But i'm using a SITECOM CN104 USB-Serial converter and the CD driver doesn't work on my OS.

I took the one for the prolific WebSite to solve my prob.

[Visilogic Serial com Trouble]

Thanks for your help guy !

The problem is solved :-) it was a driver problem now everything is OK.

It ssems that installing the same driver from a desktop Pc to a Laptop with the same OS couldn't secure it to work.

Thanks again.

:-))

[Visilogic Serial com Trouble]

Thanks Hash,

I made your suggestion but unable to synchronize the port :-(

Here is the screenshot about the advanced settings.

Uploaded with ImageShack.us

I'll try another adaptator.

That that i don't understand is why PLC can receive and transmit data ( saw with the sniffer) and why the driver say ;

Unable to synchronize!

thanks for help :-)

[Visilogic Serial com Trouble]

Hye men, thank for replies !

What Baud Rate are you using in the Terminal Software to Communicate with the PLC?

'I use 9600 bps with the terminal software on visilogic 8.6.3'

The PLc use the com1 to communicate with a PC using 9600,8,N,1,OFF.

So when trying to communicate even trying several Visilogic Speed (9600 - 57600 - 115200) i've got the same prob.

Visilogic send a break signal then Open the Comport with 9600 bps then display the Driver window Err code (206) then the state unable to synchronize.

Using the PLC sniffer, i'd monitored the Tx, Rx data after pressing the Get Plc information button on Visilolgic Communication window :

1) PLC Receive a '*'

2) PLC Transmit /A00CPF3

3) PLC Receive /00CPC1T0BFFFF45

Another option to try is before opening VisiLogic, Right-Click the Icon and select "Run as Administrator".

'Tested but nothing more.'

Thank fot your help :-)

[Visilogic Serial com Trouble]

Hye Ron,

Thanks for your answer and you right about the COM port.

I'm using a USB to Serial Adaptator witch is defined as COM5 linked to the COM1 of the PLC.

Uing a terminal software i can send/receive datas, but it seems that visilogic couldn't etablish the connection to the PLC.

Thanks for your suggestions

[Visilogic Serial com Trouble]

Hye Everybody,

I'm in trouble trying to communicate with my V570 through the com1 port of my new Laptop.

I'm under Win 7 ultimate.

When trying to get PLC info i've got this error message :

Communication : Unable to synchronize with the PLC.

Uploaded with ImageShack.us

following by the window error message : Driver Error(206), unable to communicate with the PLc ...

I can send and receive Datas from a third party software like the hyper terminal using RS232 communication.

For info, I can connect from my other Wind 7 desktop Pc without any problems.

So, anybody could have an idea :-)

Thanks

[CanOpen - SDO transfer complete]

Hye debew,

You wrote : "...I am trying to sequence messages to the drive, but need to know that the previous message was completed successfully before I start the next message..."

To know if a SDO has been successfully sended you can check/control if the transmitted Datas are sored in the device by reading them into the device using another SDO.

If the data are that expected then Proceed next SDO Or Re-attempt the Previous one 2 times again for ex. before Err..

[CanOpen - SDO transfer complete]

HYe,

"...I am trying to sequence messages to the drive, but need to know that the previous message was completed successfully before I start the next message..."

Why don't you read using another SDO the param previously wrote by your SDO ?

SDO write Param

SDO read param :

If Read = That i want then Send another SDO,

[V350 IF/THEN / ELSE ?]

You can insert a conditional Subroutine Return following your TRUE Condition.

(net 0)

--|MB1|--+--|/MB3|--------(S MB4)-(Sub RETURN)-

--|MB2|--+

(net 1)

-----(R MB4)

(net 2)

RETURN

[485 Communication]

Simply using Modbus protocol.

This comm protocol is based on sevral type of requests to exchange datas between OPLC very simply.

- Use OPLCs serial port correctly configured with the FB provided in the VIGILOGIC Soft.

- Use the Modbus functions to Read/Write the desire datas in the slave.

Take a look in the help under communication/modbus (keep away the Modbus TCP/IP) then take a look to the programs in the samples directory :

..\Unitronics\Examples\Version 861\Project examples\Communications\MODBUS

:-)

[rs232]

He mean that with the example, all it's well explaned.

From configuring the data port com.

How send number/variable you need to transmit to your Weight device.

The example send 2 type of data.

1) it send the ML 0.

2) it send a vector of 6 MI representing RTC hour in ASCII format.

All two using the protocol send function.
