Is it possible to disable/enable ping command on a 1211C AC/DC/Rly CPU?

Issue I'm facing is that we can connect to the device using TIA Portal V11 but it will not respond to a ping.

The gateway is setup correctly.

No IP conflicts.

Can't find any information on this in 1200 manual.

 Hello,

My first reaction would be is to blame any gateways the comms needs to cross before reaching the PLC.

Is it possible for you to test a connection that does not go through a gateway? Any Ethernat capable computer could be used for the task.

Good luck.

Hello kragnz,

the firmware of the CPU is responding to ping requests. However a ping is not equivalent to a regular TCP or UDP packet. Ping is a synonym for ICMP Echo Request. Which brings up the issue with that.

Network components need to pass through ICMP as well. Therefore I suggest to first off try with a direct connection "pinging" from a local PC, before you introduce switches and gateways.

At least you should check, whether the gateways/ firewalls are also allowing ICMP echo requests and responses.

Cheers 

hi kragnz,

which CPU do you have exactly? MLFB?

And which FW does it have?

 Last but not least,

IP - Adress Setting is OK?

Thanks for all the replies.

CPU is:

CPU 1211C AC/DC/Rly

Article number: 6ES7 211-1BD30-0XB0

Firmware V1.0

IP address is correct.

I have been diagnosing remotely. I will be on site early next week and will try plugging in directly to X1 Lan port and pinging there. If that's OK then it must be an issue with the sites routing.
