Hi all, I am currently trying to discover connected devices in the following architecture:
PC ← VPN → RUT956 → TSW212 → 1.CPU S7-1500 SIEMENS
2.CPU S7-1500 SIEMENS
I was able to successfully communicate between the PLCs. Everything works great when I already know the IP of the CPUs. The problem I am having is that I am not able to “see” the PLCs from the PC. I can ping them, I can connect to them, but when I need to scan the network, I am not able to see them.
I’ve done this steps:
- Downloaded the UDP Broadcast Relay package and stablish some ports
- Downloaded the SNMP package and activated with the same configuration as TSW212’ SNMP
- Activated PROFINET in TSW212
- Downloaded and installed LLDP from CLI. Is in running state
- Activated command “root@RUT956:~# /etc/init.d/lldpd -c” to activate DCP
After all, I am not able to see my devices. What am I missing? Is this even possible?
Thank you in advance.
