[Copy/Cut Operation cannot be performed (94)]

Hi Damian,

Indeed you are right. When trying to copy the element Set Network ID with contant ID you get message 94.

Workaround:

Change the constant ID to MI and then back to contant. Now you should be able to copy & paste.

[RS485]

Hi ,

Which RS485 cable are you using?

Did you set termination at both end devices?

Please make sure to connect also the 0v of the PLC power supply and the circuit board.

Which protocol are you using for communication?

[Modbus Help]

Hi,

Which PLC com port are you using for the RS485 communication?

Did you set the jumpers for RS485 with Termination?

Which RS485 cable are you using?

Please check that both the V280 and the slaves are set to the same baud rate and the Network IDs are set as required.

Please make sure to connect also the 0v of the PLC power supply and the regulators.

[4 sockets 1 port - modbus tcp]

Hi Tim,

All four socket are fully independent so you can think of it like you are using 4 independent com ports.

As each socket is independent so you can send all 4 messages at the same time (each message in each socket).

Note that for sending the next message on the same socket, you need to check the busy bit of the relevant MODBUS CONFIG.

[Pulsing an output]

Hi,

You can use a timer for controling the rate of the pulses.

Each time you can change the timer preset according to the required rate.

Connect inverted contact of a timer to a coil of the same timer. This will create a pulse generator according to the timer preset.

Then use a direct contact of the timer to activate your output.

[CANopen and SDO Download - ACK Message?]

Hi,

As you already mentioned you can check in SI225 (SDO status) that there is no error (equal to zero).

There is another system bit SB243 which indicates SDO transfer failed when it is on.

Please note that the PLC has CAN sniffer built in inside INFO mode where you can see all transmit and received CAN messages!

Using the new VisiLogic 9.3.0 you have also the option to sniff all received messages to a data table - Please help topic CANbus Message to Data Table.

Please see detailed information about the difference between "Domain Segment Transfer" and "Block Segment Transfer" in the below link:

[Networking 3 PLCs by MODBUS IP Ethernet]

Hi Flex727,

Unitronics Ethernet card supports 4 sockets.

According to your configuration you need to set in the master PLC two of the sockets to TCP master and one socket to TCP slave so that the PC will be able to connect it. (This will let the msater PLC to communicate with both slaves at the same time)

For both slaves you need to set 2 sockets which will be TCP slave so that the PLC and the PC will be able to connect to it at the same time.

Checking the status messages is good option. If you will reinitalize the Ethernet card then all the connections will be lost and you will need to reconnect both slaves. If you recognize communication problem then you can init the relvant socket.

Take a look also on SIs 103 - 106 (keep alive) for setting in the slave PLCs.

[Can't connect to v570 via ethernet]

Hi,

Are you sure this is the right gateway?

Did you try to connect the PC to one of the PLCs directly and test the communication?

Anyway please try to disable any firewall, antivirus or any other program that might block the connection.

[v130 WatchDog Screen]

Hi BenB,

In general these kind of errors are generated by watchdog timer in case the controller exceeds some predefined time and didn't pass trough Scan end. The reason can be internal loop, logical error.

Does this error occur in all V130 PLCs?

If yes then most probably there is some problem with the code.

Are you using jump to label function?

Make sure that there is no internal loop which will cause this kind of error.

Anyway if you do not find the reason for this problem send the application to support@unitronics.com and we will check it.

[DataXport]

Hi Intermat,

Thanks for the suggestion. We will consult it with Unitronics R&D.

[UniOPC read write]

Hi,

Which PLC are you using?

Can you explain in more details what is the relation between the VB application and OPC server?

Does the VB application act as OPC client? Does it has OPC driver?

[Heat meter M-Bus through RS232]

Hi Vidmas30,

If the device supports RS232 then you can connect it directly to the serial port of the V350.

Of course tou must set the same communication parameters for both devices. (Baud rate, start bit, parity, etc..)

Which protocol does Heat meter support?

Does M-Bus is MODBUS?

If yes then of course you can use FB MODBUS for the communication.

[CANbus NMT RTR Not Changing Value]

Hi,

Which values do you get in NMT status MI?

Are you sure you are not chaning this MI anywhere in the applicaiton?

See below NMT statuses and check whether they are match the status:

0 - Initializing

1 - Disconnected

2 - Connecting

3 - Preparing

4 - Stopped

5 - Operational

127 - Pre-Operational

[email with V350]

Hi fabios,

Are you using Visilogic 9.0.1?

Attach the application and I will test it with the parameters you are using.

[email with V350]

Hi Fabios,

For example if your mail server is "unitronics.com" then try sending mail to account in unitronics.com (Example - fabios@unitronics.com)

Are you using company mail server or public?

did you enter username and password?

Can you try using different mail server?

Try upgrading the VisiLogic to version 9.2.0 and upgrade all the system files of the PLC.

[email with V350]

Hi Fabios,

Did you try sending the mail to different mail address?

Try sending the mail to account which is configured in the mail server.

Please make sure you are using the latest system files.

[Trouble while uploading project from a V280]

Hi,

Which OS installed on the V280?

Using which VisiLogic version the program was downloaded to the PLC?

Try uploading the application using the same Visilogic version.

You can try also uploading using different PC.

Another try will be to download the latest VisiLogic version 9.2.0 and try uploading again.

[email with V350]

Hi Fabio,

Try to check in the junk or spam box.

[Long file names in enhanced web server]

Hi Andy,

The limitation is not related to the Web Server but to the PLC handling files with SD card.

Basically the path appears somewhere in the file.Try checking where you need to change the path to the file and also make sure to rename the file to be 8.3 format.

[Long file names in enhanced web server]

Hi Andy,

The Web files need to be stored in SD card which will be in the PLC.

As you mentioned indeed the PLC can work with files only using format 8.3 and english characters.

We have many customer who already inmplemeted the Enhanced web server using HTML and JAVASCRIPT using file names with 8.3 format.

[Importing DataTables from XML - Hebrew issue]

Hi Maayan,

Indeed you are right. We passed this issue to our R&D for examination.

[V350 Communication]

Hi,

If all the 8 PLCs and the PC are connected to the same switch then basically if you will set to each one of the deivces IP Address in the same gateway then you will be able to connect from the PC to each one of the PLCs.

In the ladder code add the function TCP/IP card init after direct contact of SB2 and configure IP address, Subnet mask and default gateway according to your network settings.

Add the function PLC name after TCP/IP card init and configure your PLC name.

Download the application and reboot the PLC.

Then using VisiLogic, Remote Access or any other Unitronics software you can access to controller via the IP address, PLC name and the port 20256 or 20257 if you did not change the sockets settings.

Please note that you can also configure each one of the sockets to other port number and TCP slave and later use this port number for connection.

[Modbus TCP to non unitronics PLC]

Hi Denis,

You can use Unitronics controllers either as MODBUS master or MODBUS slave.

If you are going to use MODBUS IP then of course the V570 must comprise Ethernet port.

Then as in any Ethernet network if you wish to connect more than 2 device then you need to use hub or a switch..

[Trouble with SLC communication]

Hi,

Currently the fix has been made in new OS which is not official yet but if you need it please send a mail to support@unitronics.com and we will send you.

Anyway the OS will be released soon.
