ICMP Mode The Internet Control Message Protocol (ICMP) allows the higher
protocol layers to detect error states on the network layer and
optimize the transmission of data packets.
Message types of Internet Control Message Protocol (ICMP)
supported by the processor module:

No ICMP Responses
All the ICMP commands are deactivated. This ensures a high
degree of safety against potential sabotage that might occur
over the network.

Echo Response
If Echo Response is activated, the node responds to a ping
command. It is thus possible to determine if a node can be
reached. Safety is still high.

Host Unreachable
Not important for the user. Only used for testing at the
manufacturer's facility.

All Implemented ICMP Responses
All ICMP commands are activated. This allows a more detailed
diagnosis of network malfunctions.
Default setting: Echo Response
