  1. Sorry my mistake, I means my SIM card is dynamics IP, after I did DDNS service and try to do port forwarding for SCADA (port 8088) but seem like the port still closing.
  2. But I used DDNS service by no-ip. But the SIM IP and Public IP for gateway is different.
  3. Q4 : Using Ethernet Q5: robustel Modem,SIM card is LTE but I I found is sim card issues.. It's dynamic ip. Thanks for reply..
  4. I think I know the issues already.. the SIM card is dynamic ip address, means cannot do port forwarding. I'm try to access the PLC Remote Operator, means I need to forward port 20257? My client's PC is only Remote Operator..
  5. WAN IP address means Public IP address? Sorry I'm not really know about networking. I need your advise. Below shows the step I had tried: 1) I login to PLC network gateway to set the port forwarding 192.168.0.29 port number 502 (*I'm not sure about the port number*) 2)In Client's PC, I tried to access to PLC network (Public IP : 502) But it failed. Which parts I missed?
  6. both are connected to internet. but this 2 network are different network. - PLC is connected to SIM Card modem. - Client side is PC or Phone connected to wifi modem.
  7. Hi All, I'm using V350 PLC to do a system. My objective is to use different network access to PLC Network for Unitronic remote operate. As I know need to do a port forwarding. But I had tried to port forward but still failed. Can someone explain me and help me for the solution?
  8. I see this topic before. but I have no idea how to use Struct Block, even trough see the help file in program still not understand yet. Can you explain how to use this block.
  9. Hello guys, I have pull somes data from power meter to plc by using modbus 485 via visilogic. Power meter data is two 16bits integers (MI), MI0 is + value and MI1 is - value. If I want to combine MI0 and MI1 convert to MF, which function I need to use? I found some people's topic say that need to use Struct function and Float convert function. But I don't know how to use its. Can someones show me example to do that?
  10. It's work! I'm using COM port1 to communicate with RS485 and use IP to communicate with PLC. Thank you so much..
  11. Hi All, I'm using V350 and trying to pull data from power meter through modbus 485. But I face the problem that cannot receive any data from power meter. I believe that the communication is failed. I'm not sure about the modbus configuration block setting for COM port 1,2 and 3. I confused my usb is which COM? my Modbus RTU is which COM, I also added 1 TCP ENTHERNET card. which means I have 3 ports. I don't know how to do the setting for it. Beside, I also don't know what is my plc network id. how to set it? My power meter address is 3 boud rate is 9600 Even, stop bit 1. I'm success to pull data from power meter using modscan. Can someone explained to me? Zoo.vlp
