Network ports
In the "Network ports" area, you can enable/disable access to the communication module via
DCP.
Clear the "Allow write access" check box if you want to ensure that no access to the
communication module takes place via DCP. This setting prevents access to the
communication module, for example, via PST.
SNMP
In the "SNMP" area, you can enable/disable the network protocol. "SNMP" is a protocol for
monitoring network components.
This setting is activated at the factory. If you do not use the protocol, we recommend that
you disable the setting for security reasons.

NTP
In the "NTP" area, you can enable the network protocol. "NTP" is a protocol for
