  1. Hi all, I have hit a roadblock and am asking for guidance. I have a V350 with an Ethernet module connected to a wireless gateway (RV50). The RV50 uses Modbus (socket 2, port 502) to connect to the PLC and port forwarding to allow remote communication (socket 1, port 20256). This communication is great and has been successful for several months. My challenge begins when we want to control the outputs on a separate wireless gateway (GX450) with AT commands from this PLC by using the Protocol TCP/IP Function. The catch is that the GX450 will be in a remote destination and we will not be able to use serial communication. I have configured and initialized socket 0 to use Protocol TCP/IP on port 20255, SB 142 and SB 143 come on, but SB 147 does not. The static IP of my GX450 is 68.25.107.225 and I'm not sure what my remote port # would be (MI1007). I have attached my file and the rungs are under Protocol TCP IP Test except for the Sock Config under Main Routine. 1.) Does this sound possible or is there an easier way? 2.) Has anyone done something like this and could offer some insight? Note: We are using the Sprint network for both the RV50 and the GX450 and have been told by Sprint that they do not offer SMS messaging on the GX450. This is the initial route I wanted to take. Thanks, Josh Goen V350 TR20 Mnet-4-30-18.vlp
  2. We are trying to connect to a Vision V700 unit by ethernet for remote access, and to confirm the ethernet is working before starting the program block where we will be sending commands to another device over ethernet. The model I am trying to connect to is as follows: Every time we try to connect over Ethernet, we get the following error message: I have checked the cable connections, confirmed that the PLC Name, IP address, and port number set for the PLC match those that the computer is looking for. I cave confirmed that the UnCmDrv1.dll driver is installed on my computer. its last log message, timestamped to match my most recent remote access attempt, shows the following: Trying to read the SB values over a USB remote lin does not help much, as many of the bits assigned to ethernet protocols and statuses are annotated (not relevant for V700). What am I doing wrong? Why won't an Ethernet-capable PLC connect to the company Ethernet network? Thank you in advance for your assistance.
  3. I need to communicate with 2 IO-Link masters via Ethernet/IP. The manufacturer of the IO-Link masters provides an EDS file for this devices. I don't find a possibility to import them in to the configuration of the Ethernet/IP protocol (like I normal do for Canopen). Is there an other way?
  4. PROBLEM SOLVED! Needed a new Firmware update Hi, I'm trying to connect a 8-port M12 Digital Input Hub, I have all the IP settings correct as I can use the web browser to connect up to the device as well, It says Assembly Instance Input: 100 / Size: 4 (8-bit) Assembly Instance Output: 112 / Size: 2 (8-bit) Assembly Instance Configuration: 128 / Size: 0 I've created a Structure for this with them being two things Inputs INT8(0..3) Outputs INT8(0..1) While watching the Data in the EIP it shows that it's trying to connect as the Device names blinks on for a split sec then goes off a couple of seconds. I've tried the RPI setting from 8 all the way to 1000, with no change. Any one know what I'm doing wrong? Thanks, Don
  5. Hallo, I'm doing Ethernet IP communication with Keyence Cameras (CVX-400) and SMC motor Drivers (JXC91 series). Everything works very well, but it took me a long time for SMC drivers to be checked: Use Run idle for O2T. I would like to ask why and what it means. I did not find explanation in help. Well thank you.
  6. I'm currently in the process of trying to order the V100-17-ET2 ethernet card but I'm having some issues figuring out the prices and availability of it. The main site that I thought to look was MotionUSA and of all the ones that I've checked (M.A.Selmon, Colterlec, and Radwell being the other main ones), it did have the cheapest price at $86 base with $25 shipping added to it which seems a little ridiculous for what it is. I guess my main question is does this price make sense, and if not is there a better source I should be trying or an alternate card that would work with the V350 that my work uses. Thanks ahead of time, -Chris

    Access SD card using DELPHI

    Hello, could you please advise me on the following: I would like to approach the SD card of a Vision 130 PLC . We developed a PC program in DELPHI which controls several PLC's via MODBUS TCP. This works fine however we would like to have a native module in this program to be able to download files from the SD card (not using the SD card suite). Please advise me how to tackle this issue. Thanks, Ad
  8. Hi, I have a problem with aplication. My Jazz should works a few minutes as Master after that switch to Slave mode ( in the loop). It works, I switch to Slave mode till set SB25 (Ethernet Connect / Listen Request), after that Jazz turns to Master (write 0 to SI214) ??? Someone can help me ?
  9. Hi. Hope someone can assist. Installed 8 v570 units at client. First tried ethernet, then canbus and then modbus. No luck. Sometimes plc loose comms with other plc's and sometimes some plc's loose comms with omron cx supervisor scada. Any assistance will be appreciated. Thanks. Rodger
  10. Hi, I have Unitronics PLC V130-J-TR20 PLC, which is a master, and two Jazz JZ20-J-T40, which are slaves. I need two of the slave Jazz PLC's to communicate with master V130 PLC. I have made configuration in PLC Program for read and write, but it's not working properly. When i set bit for request to read PLC3 (MB100), it reads it normally. But, when i try to read PLC2, it reads same value that I have on PLC3, although Communication is OK with PLC2. I have read example project, and used it to configure communication between PLC's, like you can see in the images. Regardless of what I do, one of the PLC's is not working properly, communication says it's OK, but keeps reading values from other PLC. IP addresses are different, of course, and i have typed them correctly into the MODBUS IP Configuration, like in the image. On my Jazz PLC's I have done everything like Example project in U90 Ladder says. Is there a way of fixing this? Thankful Nikola Ljubinkovic

    OPC Communication Slow

    Hi, I have two Jazz JZ20-J-T40 PLC-s, and one V130-J-TR20 PLC. I am using zView SCADA. I tried to connect them via Ethernet by using switch, but I cannot use two different PLCs on this SCADA. Then i tried to connect them to SCADA via uniOPC, but communicating is just too slow. I have just one bit that goes from 0 to 1 in 0.5 seconds, and back to 0 in 0.5 (1 second pulse), just for testing, still it's too slow. It runs normally for like 2,5 seconds, and then just stops, and changes in 4-10 seconds, or just freezes for 2-3 minutes, and then changes. My PC Spec are not in the way of this, I am sure of that, i have tried it on my weakest and strongest laptop, still exactly the same results, too slow with just one bit for each of the PLCs, that is 3 bits total. Does anyone had the same problem, is there a way of fixing this? Regards Nikola Ljubinkovic
  12. Hi, I'm using Unitronics PLC JZ20-J-T40, and ZView SCADA. I have successfully downloaded my program into PLC, and tested communication via usb (Serial), and via Ethernet (MJ20-ET1). It's all working properly. Problem begins when i try to connect my PLC to scada PC. With USB everything is working normally, but it's not an option for me to work with usb connection. I want to work with Ethernet communication between PLC and SCADA. What should i do to make it work? Regards Nikola Ljubinkovic
  13. I have been tasked with developing a centralized server that will communicate with many Samba PLCs around the world. Specifically, I need to ensure that the server can contact any PLC and 1) get a copy of the current values or 2) instruct the PLC to change a value. I want to ensure that the PLCs only communicate with the server, no other computers. The data itself is not considered secret, so the fact that VisiLogic does not appear to offer encryption is not a problem. But, it is critical that only the server be allowed to update PLC values. It is simply unacceptable that another person could connect and update values, even if it would take quite the effort to accomplish that goal. Is there any way to ensure that the PLC's will only respond to requests/instructions from our centralized server? If I send a password, as a message, that password would not be encrypted, so others could see and use it. Is there anyway to securely connect to a Samba PLC, using VisiLogic? The server will know the PLC name and the IP Address, but once again, this would be transmitted unencrypted. Is there a way to program the PLC's to only accept connections from certain IP Addresses? In summary, I want to ensure that the PLCs will listen for communication from our server, they will send current values when requested, they will update their values when told, and they will ignore any requests from others. Is this possible? Any suggestions are greatly appreciated.
  14. Is there any way to see which Ethernet socket is active on V700? I went with V700 because it has integrated Ethernet port, but now I can't use SB 147-150 like on other models that require expansion card.
  15. Hello! Another one topic PLC/E-mail. Unfortunately, I'm not able to copy with the problems. I use the ladder from Example (of course). In CMD I write "telnet pop.gmail.com 25" and I can see the protocol type used by the server. After that i tape "pin pop.gmail.com" and see the IP address of the server. The first change that I make in the ladder is IP in "TCP/IP - Tcp connect" block. The new IP is the same as IP address of the server. The second change is in the "E-mail" block. "From:" e-mail is Support@unitronics.com and the receiving e-mail is "..........gmail.com". When I press "connect" in HMI the system is able to connect. However, when I press "Send E-mail" there are two mistakes: "The server cannot receive data (DATA mode error)" and "From address format incorrect " I have tried many settings but non of them was workable. Please, give me an advise where might be the mistake!
  16. I am getting the following error when trying to initialize/go online for the first time with my V570. ----------------------------------------------------------------------- "Communication over TCP/IP could not be established due to one of the following reasons: - cable connections are not secure - incorrect TCP/IP settings (IP address, Protocol type, Port number) - the connection is currently being used by another application. " ----------------------------------------------------------------------- Right now the first net in my main routine is checking SB2, following by Set PLC Name, followed by a TCP/IP - Card Init, (setting IP to 192.168.1.10), and then a Socket Init (using socket 1, TCP, port 20256, and client set to server [slave]). In communication and OS I have tried my connection as both TCP/IP (Call) & TCP/IP (Listen), I am using a favorite with the same name and IP as specified above. My local machine IP is set to 192.168.1.253. I am connected directly to the ethernet port on the V570 with the V200-19-ET2 ethernet com port I am trying to "stop-download-reset" to go online and I get the above error consistently. I'm sure this is a basic question but I have watched all the tutorial videos and read the help files and I believe I am doing everything I am supposed to, any advice would be great!
  17. Hi, I am new to using VisiLogic and have a V570 for my project. I am trying to understand how to integrate the sensor block with my project. I've previously only used this sensor blocks with AB PLCs. Is this possible with a V570? Does anyone have some experience doing this? I will be using Ethernet/IP to communicate between the controller and the sensor block, I am just unsure how to read/write values from individual ports/addresses on the sensor blocks. Any help is appreciated. Thanks!
  18. My less than graceful great dane got his foot caught up with my communication cable to my UniStream. Needless to say he pulled the cable out of the controller along with the jack that the cable plugs into so the USB device connection is screwed. I'm trying to connect to the UniStream with an Ethernet cable and am having no luck. I plug an Ethernet cable into my laptop and into UniStream and port lights do light up. I went into UniApps to obtain the IP address to enter into PLC-PC communications to connect using Ethernet and I am having no luck. What am I missing? Also, is it possible to send the panel back for repair of the USB device jack? This panel is brand new, I didn't even pull the plastic of the screen yet
  19. hi there I was debugging a program on a V700 over a direct connected Ethernet link to the PLC and laptop while debugging eventually visilogic would randomly close with the attached error screen I could easily restart visilogic and reconnect the link to continue debugging so more of an inconvenience than anything any help would be appreciated

    Connecting Over Network

    Hello, I'm having an issue with getting the .NET driver to connect and read values. I am having no problems connecting using Visilogic, but when I take those properties and use them in the .NET driver they don't seem to be working. The interesting this is that I'm not getting an exception, so my application believes the driver is connected, but looking at the properties for the Ethernet object it appears not to be. When I put a break point on the oPLC object, it states that the object could not be evaluated because the previous function had timed out. When run it down to the last line and check the response values it is null. Here's the code: Ethernet ethernet = new Ethernet(_cell1PLC_IP, _cell1PLC_Port, EthProtocol.TCP, 3, 3000); PLC oPLC = PLCFactory.GetPLC(ethernet, 1); oPLC.SetExecuter(OperandsExecuterType.ExecuterPartialBinaryMix); // Create the write request // ReadWriteRequest[] readShifts = new ReadWriteRequest[1]; readShifts[0] = new ReadOperands { NumberOfOperands = 1, OperandType = OperandTypes.MB, StartAddress = 0, }; // Extract the shift times // object[] shiftTimes = ((object[])readShifts[0].ResponseValues);
  21. Hello, I use the Unitronics V350-35-T38, where port 1 is RS232 and port 2 is the ethernet card. When I had setup GSM modem on the port 1 and I had tried to download the program to the PLC I had got a message that I had to change the firmware (OS) in the PLC to the version which support ProfiBus and dial function. So I did that, but then the ethernet card was unavaible. I need both - GSM modem and ethernet card. I tried this in the latest version of Visilogic. Then I tried 9.6 version of Visilogic because in the past we used both and we used this version. I do not know why now it is not possible. Could you help me? Thank you in advance.
  22. Hi, I have a JAZZ2 PLC(JZ20-JT40) with OS V2.35(B08) and with ethernet addon(MJ20-ET1). The plc comes with 2.36 OS but, I have to reflash it because its totally crashed somehow. I can't start it. I am able to connect with the programmer software(V6.6.6 latest). I want to acces to the plc by modbus communication. I set up the sample program by the instructions on the help topic. The modbus topic is shows that, I must store some values to SI. I attached the screen of the sample program. I think the SI values displays weird values. What do I wrong? Thank You
  23. Hi, I have a problem with ethernet-connection, the PLC is V1040 with V200-19-ET1 -ethernet card. I've been using ethernet-connection with Samba (Modbus TCP connection to SCADA software) and it worked fine! The problem is, that when I plug ethernet cable from v1040 to ethernet switch, switch seems to have no activity. Not even Link/act -leds doesn't turn on. When I keep touch screen pressed and enter setup, it show MAC address and IP of ET1, so PLC recognizes that there's ethernet card installed. I've been trying another PLC and another V200-19-ET1, different ethernet switch, different cables, even straight connect to my laptop with cross-connected cable with no results. No activity in ethernet connection. What am I doing wrong? Does V1040 have jumpers that are needed to change?
  24. Hello! Another one topic about PLC/E-mail, unfortunately, I'm not able to copy with the problem... I use the ladder from Example (of course). I setted up PLC's IP, mask and gateway. Firstly, I wrote "telnet pop.gmail.com 25" in CMD to see the protocol type used by the e-mail server - ESMTP. After that I dial the text "ping pop.gmail.com" to see the IP address of the server. I changed a setting in "TCP/IP-Tcp Connect" block. The "Remote IP" inside the block is equal to IP address of the server. The last change is in "E-Mail" block. "From:" e-mail is "support@unitronics.com" and "To:" e-mail is "..........@gmail.com". When i press "Connect" in HMI the connection is done. However when I press "Send E-mail" the program shows two different errors: "'From' address format incorrect"; "The server cannot receive data (DATA mode error)". Please, tell me where might be the mistakes to try to solve them!
  25. I'm trying to connect my PC with a Unitronics PLC. I would like to use Modbus over TCP/IP for this purpose. This is the first step in my project. Later on I would like to connect it to a Rabbit Wolf (BL2600) to exchange I/O. I first want to connect the Unitornics PLC to my laptop to get a decent understanding of the Modbus TCP/IP protocol used by Unitronics. At the moment I'm already stuck, so I hope that someone could help me. I did read the documentation about Modbus Application Protocol on: http://www.modbus.org/docs/Modbus_Application_Protocol_V1_1b.pdf I'm using the Unitronics example code: V280_Ethernet_TCP_MODBUS_IP_Master (without any changes) I used the Vellamod tool to connect and send data: http://www.tuomio.fi/vellamod/index.htm (I'm running windows 8, so I have some problems with other tools and this one seems to work nice) I'm using Wireshark to inspect the TCP/IP traffic. However, I'm now in the current situation. The laptop connects, but I don't get any response. I connect to 192.168.192.5 on port 502. My laptop is set to 192.168.192.10 (subnetmask 255.255.255.0, gateway 192.168.192.254) I try to send the following (see attachment for a printscreen): byte 0: transaction identifier = 0 byte 1: transaction identifier = 0 byte 2: protocol identifier = 0 byte 3: protocol identifier = 0 byte 4: length field (upper byte) = 0 byte 5: length field (lower byte) = 2 byte 6: unit identifier = 255 byte 7: MODBUS function code = tried 3 (Read Holding Registers) and 4 (Read Input Register) byte 8: 00 byte 9: 26 (I try to read MI 38) When I than inspect the transmission with WireShark, I get the following Source: 192.168.192.10 Destionation: 192.168.192.5 Protocol: Modbus/TCP Length: 64 Info: Query: Trans: 0; Unit: 255, Func: 3: Read Holding Registers[Malformed Packet][Malformed Packet] When I set: byte 5: length field (lower byte) = 6 I get no error, but I also receive nothing with the Vellamod tool. According to Wireshark I receive the following: First Source: 192.168.192.5 Destionation: 192.168.192.10 Protocol: TCP Length: 60 Info: asa-appl-proto > 49933 [ACK] Seq=1 Ack=325 Win=1024 Len=0 Followed by Source: 192.168.192.10 Destionation: 192.168.192.5 Protocol: TCP Length: 64 Info: [TCP segment of a reassembled PDU] And finally Source: 192.168.192.5 Destionation: 192.168.192.10 Protocol: TCP Length: 60 Info: asa-appl-proto > 49933 [ACK] Seq=1 Ack=335 Win=1024 Len=0 On the PLC HMI nothing is changing (Socket 3 total transmits: 0;Socket 3 total reiveces: 0) The only strange thing that I can see is that it (Unitronics) seems to use destination port 49933, but I don't know whether this is wrong or right. Hopefully someone can help me. Visual basic code, would also be more than welcome. Kind regards, Peter
