Hi,
I am developing a system to send Alarms of a PLC trought an Ewon.
Basically The Ewon should be directly connected to the PLC (s7-300), and then it uses a Sim card (data one) to publish all the data over the internet at a public address. The public Ip to which I am sending datas is dynamic so I made a dynamic DNS to catch the Ip variations.
I have configured the Ewon and the PLC, and they do exchange datas. We’re actually doing our test with a s7-1200 plc trought its profinet port, ISOTCP protocol, the only one we could use in this case.
The first issue is that as I try to communicate with Ignition sometimes it gives me back connected status, sometimes connecting.
The second one is: how do I setup tags in Ignition?
I would use directly the OPC-UA server, and I suppose I have to use the Siemens Addressing mode, like [device name]Address. But It doesn’t work with me, especially I’m trying to read a merker, what should I type to setup tags?
I know it’s kinda basic in someway, but I really need some help.
P.S.
I report what I have done since now in the attached files.
