2.2.1

Supported Ethernet services: ICMP, ARP, SNMP, LLDP

Supported Ethernet services: ICMP, ARP, SNMP, LLDP
The module supports the following standardized Ethernet services:
• ICMP - Internet Control Message Protocol (RFC 792)
ICMP is a protocol used to transmit informational and error messages over the Internet
protocol.
• ARP - Address Resolution Protocol (RFC 826)
ARP is a protocol used to determine the hardware address (MAC) of an associated Internet
Protocol (IP) address.
• SNMP - Simple Network Monitoring Protocol (RFC 1157, RFC 3410)
SNMP is a protocol for transmitting management information across networks.
• LLDP – Link Layer Discovery Protocol (IEEE 802.1AB)
LLDP is a protocol for identifying neighboring devices.
2.2.2

Port diagnostics

Port diagnostics
Depending on the BusAdapter used, the device supports special diagnostic alarms that signal
the quality of data transfer on the medium used.
2.2.3

Disabling of ports

Disabling of ports
The device supports the deactivation of the port by parameter assignment, so that all
communication on this port is prevented.
2.2.4

Minimum update time 1 ms

Minimum update time 1 ms
The shortest update cycle of IO data for this device is 1 ms. To achieve this value, the
controller used must also support this time.
