rajsiyer posted a topic in Modicon / Telemecanique / Schneider ElectricI am attempting to download a Vijeo designer application to a remotely situated Magelis HMI over the cloud by means of a VPN. Vijeo designer's built-in help indicates that this is possible and has provided an example. BTW, I am using Vijeo Designer basic v1.1 & the HMI model is GXU3512. However, I find the fields for router IP and TCP port nos. all deactivated. How to get pass this roadblock? I'll appreciate any suggestions. Thanks a million
Good day everyone, before I start asking my question, just want to let you all know that my knowledge with PLC is not that good. I'm still learning on how to do it. So currently I'm working on a project that trying to obtain data from Omron PLC. I was told that I can't touch the Omron PLC program or modify it. That Omron PLC is connected in an isolated network within a router. Other than adding Network Card on the device, can I use another PLC (any brands) to get the data from that Omron PLC through the router? The communication protocol using here is Ethernet. Can i just tapped into the network and take the data with that way? Or the other method I'm thinking is that, the Omron PLC will feed the data to a server, can I just obtain that data from server by using OPCUA? I heard there's some PLC that have the OPCUA function, I just make my PLC into the cilent and request the data of that Omron PLC from server through Ethernet. Is this possible? Please let me know whether my method works or not, thanks in advance guys!
Transistor posted a topic in NJ Series / Sysmac StudioI use Netgear routers with multi-NAT capability to attach machines to the company LAN. One of the advantages is that similar machines can have identical network addressing schemes while a multi-NAT router on each machine can be used to assign unique external addresses. The usual error on these setups is to forget to assign a gateway IP address and so the PLC can't respond to requests from outside its subnet. I have the router set up as normal (as I have done a hundred times before on other machines). PLC has correct IP address, subnet and gateway (that of the router LAN address). Router has NAT rule configured, correct LAN subnet, etc. I can PING the PLC from the company network. This implies that the router, wiring, etc., are all OK. If I disconnect the PLC ethernet cable during a PING I get errors. This implies that the address is unique, etc. Controller --> Communication Setup --> Ethernet connection via hub --> Ethernet communication test --> "A communication error has occurred." Has anyone seen this? Any reason why it shouldn't work as I expect? Many thanks.
