Hi sgull, We are considering this option but still do not have a decision yet.

Hi, Which socket and port number are you using? Make sure the socket is configured to TCP slave. Review the topic "What are the steps communicate with the PLC via Ethernet?(PC to PLC) "from FAQ. http://www.unitronics.com/Content.aspx?page=FAQ#faq8 You might face this problem due to firewall antivirus or other security programs that runs on your PC. Try to turn off any security programs and test again.

Hi, When working with MODBUS over GPRS you will need to use "serial" MODBUS FB. After connection established between the PLCs activate the MODBUS CONFIG. Attached are examples for V130 Modbus over GPRS. (You can upgrade the applications to V1040 from project menu convert to color). The Modbus client GPRS application will perform the call to the Modbus server GPRS. (If you don’t have static IP then power up first the SERVER application check on the HMI what is the IP, then change in the client application the IP in GPRS CALL FB) 130 ModBus Client over GPRS.VLP 130 ModBus Server over GPRS.VLP

Hi, Usually in systems where you have many tags and the update rate is critical, We recommend using MODBUS instead of UniOPC since there are only 2 elements (PLC and SCADA) and not third element between them. Most of SCADA systems support MODBUS driver and there should not be any problem to implement such connection. You will need only to set the PLC as MODBUS slave.

Hi, There is no built in application for this function but it can be programmed using communication functions. The two V1040 will be connected by communication the main panel will transfer all the data to the remote panel and also whenn pressing on buttons on the secondary HMI it will send the requests to the main panel. The displays will be the same and according to the data the remote panel will show the same as the main. The communication can be either by Ethernet or CANBUS depending on the distance and area.

Hi, There are 2 ways to send string as HEX. You can use either the control characters or using the variable stream. When using the stream variable you will need to link a vector which holds the values required. Attached is also example application for sending this string in both ways. send HEX.vlp

Hi, The ways I described in my previous post will send the string in binary way. You can send the string from the PLC to Terminal application and check that you send the right sting. If you still unable to get a response then attach the ducmentation of the protocol.

Hi, Upgrade the OS to the latest and test again. The latest OS is 3.4(25). You can update the OS from the Web from Visilogic help menu -->Check for updates --> Operating system

Hi, If you wish to send the string as binary then you can use either the control characters or using the variable stream. When using the stream variable you will need to link a vector which holds the values required. See attached picture for protocol send using the control characters.

Hi, There is no direct option to reset HSC which is on expansion unit. See the logic in the attached which implements reset for HSC.Instead of working directly with the MI that linked to the HSC (which you are unable to change/reset) working with the virtual HSC.

Hi, If your encoder supports A & B signals (I hope so) you can select in Hardware configuration HSC as” Shaft encoder x2” or "Shaft encoder x4”. The first option – PLC counts the rising edges of A & B signals. In the second (x4) both rising and falling edges of A & B.

Hi, As I understand the page "bc.htm" is a page which you created and put it in SD card folder Web. In this case the link should be <a href="/Web/bc.htm&User=[sT20,ppppp]&Pass=[sT21,ppppp]">

Hi Joe, Please send the project to support@unitronics.com and we will fix this problem.

Hi, See FAQ link below "What are the steps communicate with the PLC via Ethernet?(PC to PLC)" http://www.unitronics.com/Content.aspx?page=FAQ#faq8

Hi, Basically if you are using the function which receives SMS to vector then you need to configure in SI199 the Start of Vector address of MI. Of course it is recommneded to allocate length of 80 MIs in case you will receive a message with 160 characters long. You can find example in VisiLogic example Project examples\Communications\SMS\V570_Display_any_SMS.vlp

Hi, A message containing only English characters may contain up to 160 characters. A message containing non-English characters may contain up to 70 characters.

Hi, What is the condition you are using to activate the SD safely remove? Implement the condition for SD safely remove as apeared in the attached picture. If you still face the same problem try upgrading VisiLogic and the PLC system files to the latest.

Hi, Which communication type are you using? (RS232,RS485, Ethernet etc..) Which UniOPC version are you using? Make sure you are using the latest UniOPC sever 2.0 Try to increase the time out in channel settings. Anyway if you still face the same problem then check the option to use MODBUS instead of OPC. This way you do not need to use UniOPC server. You just need to set all PLCs to be MODBUS slaves and change in InduSoft to use MODBUS.

Hi tonto, You need to configure the V290 and the Scaime eNod3-C A/D loadcell device to the same baud rate. It is recommeded that the ID of the V290 will be 1 (In CANOPEN there is a priority to ID1) and you can configure ID 2 to the load cell device. In CANOPEN configuration you need to configure the other paramters of the loadcell device such as NMT, TPDO and RPDO in order to be able send/receive PDOs and also send NMT commands. If you are using VisiLogic 9.3.1 you can review two examples for CANOPEN in folder C:\Program Files\Unitronics\Unitronics VisiLogic_C\Examples\Version 900\Project examples\Communications\CANopen Using NMT control commands you can set the device to stop, pre-operational, operational etc.. using NMT node guard you can check the device status.

Hi, Turn off the UAC before installing UniOPC Server. You can find details how to turn off the UAC at:http://www.unitronics.com/data/uploads/VisiLogic_Software_New/Disable%20UAC%20Vista%20+%20WIN7.pdf

Hi, Check the following: * Communication parameters. The default parameters are 9600,7,Even,1 If you did not change it then make sure to set these parameters in UniOPC Server channel settings. * Make sure selected PLC type M90/M91/Jazz * The PLC name you set in UniOPC server is the same name you set in in the syntax of the tag.

Hi, The file names is ASCII string and you can keep it for example in Data table. Then you can copy from the Data table the file name to the indirect MI in Delete SD file.

Hi, You can delete files from SD card using the Ladder utility "Delete SD file". You can find this utility in SD menu --> SD file Untilities.

Hi, Is it possible that you remove the SD card while there is write in progress? Anyway before removing the SD card please use the function "SD safley remove". Make sure that you are using the latest versions of system files and SD card suite.

Hi, Indeed you are right. When using the Root folder you can view up to 60 files using SD card explorer due to the 4 sub folders. As you mentioned also there is an option to view more than 60 files using the variable “Browse SD content”. The reason why there is no option to view more than 64 files/folders usin SD card explorer is due to the fact that the communication buffer for files table is limited to 512 bytes. (64 files/folder names * 8) 8 is the file name length.
