Hello,
I hit send on my last post before I could finish it, and it said that it needed pre-approval to post, so I’m just going to complete it here. Delete my last post from an the prior hour. Thanks.
I’m pretty sure this is a firewall/protocol blocking issue, as I can connect to many of our other systems of nearly identical design without any issue.
I am able to connect to the ewon via talk2m, but some odd things are happening that are preventing me to fully connect to the allen bradley 5380 and the siemens TP1500 in our system.
I can ping the allen bradley 5380 PLC when it’s the only device plugged into the machine ports (beside the top-right WAN port), but I can’t reach the web landing page or see it in rslinx. when only the Siemens TP1500 HMI is plugged in, I can see it on the profinet explorer, but I cant ping it or reach the web landing page, or see it in the TIA portal software.
We typically set up our systems so that they operate if the ewon needs to be pulled, so we network the PLC directly to the HMI, and then the HMI to the ewon’s machine port. This works due to how the HMI’s ports act as a switch at the HMI’s X1 interface. But, oddly, I can’t ping the PLC. The activity LED’s shared by the ewon and the device used just don’t seem very active, but they are blinking occasionally, so the ports and cabled are unlikely to be faulty.
I did try to ping from the ewon’s IDE program, but couldn’t get it to reach anything.
Again, I suspect an advanced firewall or protocol blocking of sorts.
Backup + support files.
