[Two serial connections in a PLC]

Is it possible to have two serial ports in the V130.  It will require an extra card to be inserted into the PLC.V100-17-RS4 or RS4X.

[bar code reader]

Yes. 

[How can I input parameters or change it?]

Read the help file, look at HMI variables.  Also check out the example programs.

I don't believe there is any problem with reading a Data Table row on every PLC cycle.

Your right the PLC won't have an issue with it and it will function, however if you then want to manipulate the data after reading it you can't because your just going to over write it the next cycle.

[How to use Data Table Read Row/ Column]

Hi Plum,

The way that the read is set up your always going to be reading row 0.

In order to read other rows you would need to assign and MI as a pointer(the number stored in it will be the row read).

Also you'd only want the read bit to be pulsed not on constantly.

All good.   I think we've all had one of those days.

Hmm sorry missed that somehow

Do you have The SDcard Explorer installed?  If yes set it up to listen (Ethernet listen)on a port say 20275 and change the port in your tcp connect to match.  Click ok the click listen.   Set the IP the PLC is to connect to your PC's .  Trigger the connection thru the PLC LOGIC if it connects SB 150 will set and you can browse the contents of the SD card in the ad card explorer window.  This will let you test your connection logic.

In this specific network can you access a different npt server?

 With the PLC functioning in different networks it would seem to be something local to this network.  Can you work from the outside in having the plc make a request from a public ip directly from the ISP's modem or router and then move it back behind any firewall/DMZ which is the first line of network security if it works.  So long as it keeps working keep moving it back till it stops the last line of security you put in front of it should be your issue.  

Something else to check out would be managed switches. Is there a proper route  from the PLC's local IP address to the outside world.  Aus suggested plugging a PC in and checking the connection, take it one step further and assign the PCthe same IP as the PLC.  Some facilities and network admins assign static IPs from different sub nets than the DHCP pool a PC would use.  Which can make a PC on the same drop work but the PLC won't.

[FTP Client Issues]

Dave,

 

I've never tried connecting to an FTP server but I have connected to PC's with the PLC initiating communication.

1) does the SB 150 go high ever stating that the PLC is connected?

2)The protocol Scan FC in net one will only be active for 1 scan on the positive pulse of MB 100 so long as all the conditions in front of it are active is this the intended operation? or did you want it checking for incomming messages when you are connected?

SD card stands out to me as the Samba has no SD card slot. 

 

Also check what your using for memory as the Samba series has a smaller memory space for opeands.

[Samba 4.3" with modbus RTU communication]

Hi Jelmer,

It should be possible, another option would be to look at the V430 which is expandable so you wouldn't need the output modules.  You'd only have to communicate with the energy meter.

[MODBUS to Powerflex issue]

Hi John,

Are you doing any Vector Fills or Copies where the index starts below MI 13 and the length is causing MI 13 to be over written?  The find function will not show MI13 linked to the Vector Copy or Fill if it's is part of the MI's in being written to due to the length of the vector.

[After the OS update, the program does not work.]

Yes it is possible to downgrade the OS , you need the OS update and bin files and then can use the OS tab from the communication and OS window to load them into the PLC.

[Problem connecting with a V1210]

 Can you post your DataXport project?

[Problem connecting with a V1210]

I don't know I've never done it that way.

If you want an excel file of the data table you can do the following:

Specify the Excel folder to save the files to  by clicking Project-> Excel/.csv file properties

In the site under Excel/csv files select: Create Excel files 

When a call completes the system will create an excel file and store it in the folder define in the Excel/.csv properties.  ( I can't remember but you might require excel on the computer running DataXport)

Hi, thanks for your message !

I'm using ethernet.  In design>pc ports it appear as : "Ethernet(call)" so i guess i should select "TCP/IP(call)" in connection type ?

Yes.

[Problem connecting with a V1210]

Hi Gael,

Are you communicating via Ethernet or Serial ???

 

Connection -> Communication settings

Will let you test the port you are trying to use in DataExport, however in order to set the port up for DataXport to use while running you need to go to the Design drop down menu

Design->PC Ports

Set up the port you want to use in the window which pops up.

Then when you set up the site make sure you have the correct port selected.

Good to know it's solved.  Thanks for the update. 

[Samba Screen sensitivity]

By any chance are the operators wearing a glove made of cloth material?

[Download error, can't get past it]

Second message is from Visilogic checking the o/s files that it would upload to the plc and stating that they are the most current available.

[Unistream Modbus limitation]

As Flex says your going to have to break it up in to multiple reads.

[DataExport Error]

Can any one explain what causes this error to randomly occur in Data Export?

I can click ok and DataExport will close and then I can restart the project and it will run fine for anywhere from 1-5 days, then error again.   

I've tried stopping the project running and removing the log files which are created, but still have the same problem with the random crash.

It's running on  a Win 7  32 bit machine that is fully updated.

Any ideas?

Hi Vitor,

 

The V350-35-TR6 is able to do what you describe above, Have you tried breaking the program down to verify.

1) you can receive text messages

2)that you can send text messages

Then work on melding them together.

What modem are you using? have you verified that the PLC can communicate with it properly to send and receive text messages.

[Read values from Thermocouple J type in Samba 4.3"]

The Samba is non-expandable so it is not possible to add the required thermocouple input(s) to the unit you have.   As Dan stated you'd have to look at the -RA22 or -TA22 models.

or you'd need an external module to convert the thermocouple input to a 4-20 or 0-10V signal that the PLC can accept.   Phoenix Contact or Weidmuller are two companies which have this type of module.
