How to connecting M580 via https through NOC0301

Step 1:

Enable backplane port from NOC Advanced Configuration.

Step 2:

Enable Https on both PLC and NOC, make sure firmware version of your PLC is >=4.30

Step 3:

Once step 2 is done, you shall be able to ping your PLC port 443.

Step 4:

Open Security Editor, first click Generate Self Signed Certificate

Step 5:

Then in Certificate whitelist, select PLC IP address then click Trust Certificate then apply.

Step 6:

Then Connect PLC via Https

Summary:

When trying to connect PLC via Https, the Https server is in the M580 not in the NOC0301. (NOC doesn't have https server embedded), so always need to use the IP address of PLC (Not NOC) to establish https Communication. It is possible to plug ethernet cable into the port from NOC module but still when connect from PC, still need to use PLC IP address. Ping 443 port with NOC IP address will always fail, because NOC doesn't have https server embedded. Ping 443 port with PLC IP address will work if backplane port is enabled. This way, the https communication is going from NOC module through the backplane and eventually reached PLC https server.
