Yep, both have static IP on WAN side. I have port forwarding function on routers. UPnP and NAT are enabled. Static and Dynamic Routing. DNS Server and Dynamic DNS. I am still googling. Most of this is Greek to me. I am not Greek.

I have 2 routers with fixed IP sim cards. I plan to leave one at customer site and carry one with me. Can someone give me the lowdown on how to set this up. PLC types will vary. Omron, AB, Codesys, Siemens. I have been googling for 2 days and there is a lot of general help but nothing that seems in depth enough for me. I would ideally like to know how these networks work and what I am doing by changing the various settings. I understand that different PLC types may require different approaches. I don't know about VPN tunneling, does this require a PC at both ends? All input greatly appreciated.

I am trying to send some simple production data from a PLC over the internet to be viewed by PC's. I seem to have many choices. First task is to decide on a way to send the data. I have seen DDE, emailing, ethernet packet sending. I am not too familiar with these, but have sent CSV files from Omron ethernet units before. This was a function of the unit itself though. I have purchased two routers with fixed IP sim cards as I cannot get our computing dept to play ball until I have a solid solution in place. I am a controls guy, but my knowledge of the computing and ethernet side is a little limited. With regards ethernet, I am guessing a little here, but could I set up a system to send data packets. Then, if I set up port forwarding on my router/s would this data be sent from one router to the next automatically? At one point I was looking into writing code to send an email, but I struggled to find all of the information required. A function block for this would be very useful. I have seen some, but they only seem to be for text strings. My first goal is to send the data successfully by any means. My second goal is to send it over the internet. My third goal is to find a way to display it effectively (CSV to Excel, web page, DDE in excel). I am using an ABB Codesys 2.3 plc, so this isn't as straight forward as the AB and Omron I'm used to.

I am wondering whether anyone has any information on how to transfer data from a Codesys 2.3 PLC (in this instance I am using an ABB AC500 PM581). I am trying to set up a simple data transfer system, but have fallen at the first hurdle. Firstly I would like to send some basic data (numerical counter/timer values). Be this by DDE, Email, to MySQL or whatever, I am not too bothered at present. I would like this to send regularly i.e at the end of a shift. I have a router with a fixed IP I want to use at the machine for this. I also have a fixed IP sim router I would like to be able to dial into the machine with. Two problems really. Sending data and remote access.

I have configured a Devicenet wireless slave successfully on a network. I have tried to change the node addresses of the devices connected to the slave by initialising it to default settings (using SW3.6 on etc until dF is displayed). When I try and assign the IO again (SW3.6 on, SET mode, SW2 etc) with new addresses I get a d0 error on a node and when I try and press SET it gives me a C4 error on the Wireless slave node number. I have tried numerous address settings for all addresses. I have tried it while assigned and not assigned to the Master. The manual doesn't give any information on C4 error and d0 states IO duplication error of slave, Reset node address of slave.# Am I missing something?

Is it possible to set up a network whereby a DRM21 Devicenet card can be used in a rack without a Processor. I am hoping to set up an NSJ5 as the system PLC and Devicenet master and use an old CS1 backplane and IOs with a Devicenet card fitted as a slave. Is a PLC necessary in the rack to make this possible, or will the card just act as a remote slave? Thanks for reading and I hope someone can advise.
