Hi Fort, Please make sure that the UAC is turned off. Please try to turn off any windows firewall or Antivirus programs which might block communication. (I know about kasperski which blocked communciation) Did you tried cross cable from PC directly to the PLC?

Hi Paul, The only way updating BOOT file is using serial connection. If there is no way to access the PLCs for updating them with the new version then you can stay with VisiLogic 8.6.3 VisiLogic version 9.0.1 mostly realeased for the new V1040 and new PTO functions.

Hi, As the support of Sd card functionality is based on BinLib and Boot then there is no way the sd card can function while updating those layers. As you know before updating, the system deletes the current version and then installing the new one. At the moment that the BinLib and Boot are deleted the SD card stops functioning.

Hi Damian, In general you are right but since there was major change between version 8.6.x to 9.0.x then there is a need also to to update the BinLib and Boot. As I mentioned above there is no option to clone boot and BinLib since the SD card works on those layers. Please note that the Boot and the BinLib versions are changed very rare compared to OS version. Possible workaround: First you can prepare 2 clone files - one for version 8.6.x and one for 9.0.x Then you need to check the versions of the Boot and BinLib of the new PLC and download the relevant clone. Version 8.6.x - Boot 2.2(02), BinLib 1.3(04) Version 9.0.x - Boot 2.2(05), BinLib 2.10(00)

Hi Roland, In General you are right but VisiLogic version and Boot & BinLib versions are not stricly related. If for example there was a bug found in Boot and we fixed it, we are forcing also for updating the boot.

Hi Roland, Indeed the clone file contains also the OS but it does not contain the BinLib and Boot. When upgrading from VisiLogic 8.6.3 to 9.0.1, you must update also the BinLib and Boot. (Same for vice versa) There is no option to clone boot and BinLib since the SD card works on those layers. After you already updated the system files, next time you wish to update a new OS and application you can use the clone file.

Hi, 1. The timer format MM:SS:hh used in the keypad entry variable forces the timer resolution to 1 second, so you get an accuracy of ±1 second. if you will change the timer format to SS:hh this will not happen. Please note after the keypad entry is completed the timer resolution changes and the non-relevant digits are zeroed. Timer resolution changes according to the following rules: In case that the chosen variable format is HH:MM:SS.hh: The best resolution according to the entered value is selected automatically. For other variable formats the following table applies, regardless of the entered value: Entry-Variable Format Timer Resolution After Entry is Finished HH:MM:SS 10 seconds HH:MM 10 seconds MM:SS.hh 1 second MM:SS 1 second MM 1 second SS.hh 10 milliseconds SS 10 milliseconds 2. There is also a time function in ladder. Please use indirect clock function and link the relevant MIs (Which you used in the display). Then you can set a net -- Day of the Week --indirect Hour -- (O5)

Hi Paul, If you wish load clone file or application from VisiLogic 9.0.1, you must first update the system files (BinLib, Boot and OS)to the controller of VisiLogic 9.0.1. Same if you are using VisiLogic 8.6.3, if you wish to load clone file or application the PLC must contain the system files of VisiLogic 8.6.3

Hi, I tried to simulated the error using V570 with OS 3.1(31) without success. Attached is the application i tested with. I tried to reser alarms from Groups view or details view but no error occured. Try updating the OS to the latest and test again. V570 Alarms.vlp

Hi Maxim, As I mentioned using UniOPC server you will need to configure the items. when using OPC client i sent you please follow the steps: press on connect button. Select server versions 1.0 & 2.0 Select UniOPC server in the box and press OK. Press on add item and in item name write "VISION-350-105.MI10" --> done. Now you should be able to see MI10 value.

Hi Maxim, I'm not familar with ICONICS OPC DataSpy but you can download OPC client which we use here for testing in order to determine that the communication works properly. You can download it from: http://ftp.unitronics.com/Downloads/OPC%20Client.exe Then use syntax as i mentioned before.

Hi Maxim, As I understand SB148 is on when UniOPC is connected to the PLC. Did you check with other Unitronics software that the communication works properly? You can check using Visilogic the Ethernet communication using online mode. Please make sure you are configuring the Tags in OPC client with the right syntax. The syntax used to define the 'item' must be structured as follows:<PLCName> <ItemPrefix> <Address> For example if the PLC name is MAXIM and you wish to read MI10 then the syntax will be 'MAXIM.MI10'

Hi, You can check the price of V130 with Ethernet port comparing to the M91 with this converter. Please note that using V130 Ethernet port you can open up to 4 sockets and of course this PLC has many other advantages such bigger screen, String library, SD card, Trends, Web Server capabilities and much much more.

Hi Innov, There is no direct way to link the phone numbers to MB. You can use the indirect phone number for this application. The indirect phone number is linked to a vector of MIs. You can build a Data table which will be the phone book. Then each time you want to send the SMS to specific numbers, you will read the relevant number from the table and then send the SMS.

Hi, i'm not sure why the value you send is zero. Are you using struct or Bit to Num for structing the data? Are you activating those function every scan? If yes then please activate it only when buffer of the relevant message is equal to 0. This is 8 bytes per PDO. For each PDO send there is a buffer of 8 messages. Yes you can write all PDOs in one scan.(you cannot send 5 PDOs - Unitronics CANOPEN supports 4 PDOs (PDO1,2,3 and 4))

The PDO size (8 bytes) is a standard of CANOPEN and it is not limitation by Unitronics. You can check the EDS file of the CANOPEN device and see that the PDO size is 8 bytes maximum. The limitation of Unitronics CANOPEN is that it supports up to 4 PDOs. (PDO 1,2,3 and 4) As I mentioned if 4 PDOs (PDO 1,2,3 and 4)is not enough then you can use SDOs.

Hi, Unitronics CANOPEN supports PDOs 1,2,3 and 4 so basically for each node you can send/receive these 4 PDOs. PDO is built to transfer specific data (Which can be configured by the user in most cases) and indeed its size is 8bytes which cannot be increased. Another way of reading/writing data with CANOPEN is using SDO. You have 2 types of SDO functions, SDO download (for writing parameters to third party device) and SDO upload(for reading parameters from third party device). Using SDOs in a matter of request & reply you will be able to handle vector of data. Please note that usually SDOs are used for programing and PDOs for exchanging data with the device but there are also users which use SDOs for exchanging data. Actually the memory mapping is determined by the CANOPEN slave device so using Unitronics PLC you can choose your options for handling the data either by PDO or SDO. VisiLogic offers also other functions for mapping the received/sent data in easy way. (For example the function Map Register bytes) Which third party device are you communicating with? Does it support MODBUS TCP? If indeed it supports MODBUS TCP and the registers you wish to read/write are continues then indeed using MODBUS you can send one command to read/write all of them.

Hi Bruce, Attached is example application for multiple ID & passwords. This application based on a DT which contains the IDs and password and then according to the ID it will search for the right password. This applicaiton using password variable and the digits entered are not visible. password.vlp

Hi, The resolution stated in the graph, is the actual resolution. It depends on many factors. For defined sensitivity and time, the stated number is the real one. The other numbers in the result are not relevant – not precise.

Hi, Please note that there are 2 slave address tables, one for standard vision and one for enhanced vision. You need to use the Enhanced slave address table - please note that the addresses are in HEX. For reading coils i assume that the address will be 10001 + offset - Can you try it?

Hi, If SB150 is going off that means the communication is lost. You can try set a value of 20 in SI110 (Socket 3 TCP/IP Connection Keep (units of 100 msec)). This SI enables the PLC to reconnect when there is no communication from the connected device for the defined time

Hi, I tested your application using V570 as master and V130 as slave and it works properly. Please try using other MODBUS commands as appeared in slave addressing you posted above. (For example command 1 read coils) It seems that command 5 does not apear in the document you posted. You can try also changing the register addresses.

Hi, Do you need to send the checksum as binary? When you configure the check sum in FB Protocol Send try to change the format (The first field combo box) to binary.

Hi, Which VisiLogic version are you using? Which OS version installed on the PLC? Make sure you are using Visilogic 8.6.3 and the latest OS 3.1(30) If you still unable to use MODBUS with the device using V570 then attach the application you are using so i can test it on my desk.

Hi, Does the power Led and the comm led on the EX-A1 are On? Usually the Run Led is blinking if the hardware configuration does not match to the I/O that physically connected. First of all did you configure in VisiLogic Hardware configuration the I/O you are using? Make sure that you configured the I/O the same order as it is physically connected. After configuration is done download the application to the OPLC. Note that both the OPLC and the EX-A1 must be connected to the same power supply. You can also review the EX-A1 manual at: http://www.unitronics.com/Data/Uploads/IO_expansions/EX-A1%2012-24VDC.pdf
