Simple Network Management Protocol – SNMP
Simple Network Management Protocol (SNMP) is the network protocol developed
to manage devices in an IP network. SNMP relies on a Management Information
Base (MIB) that contains information about parameters to supervise. The MIB
format is a tree structure, with each node in the tree identified by a numerical
Object IDentifier (OID). Each OID identifies a variable that can be read or set
using SNMP with the appropriate software. The information in the MIBs is
standardized.
Various SNMP client software tools can be used with the Series 30, 40, C264 and
Hx5x range. Schneider Electric recommends using an SNMP MIB browser which
can perform the basic SNMP operations such as GET, GETNEXT, RESPONSE. To
access the network using SNMP, use the IP address of the embedded switch in
the Redundant Ethernet board.
Simple Network Time Protocol – SNTP
Simple Network Time Protocol is supported by both the P634 and the Redundant
Ethernet switch. SNTP is used to synchronize the clocks of computer systems
over packet-switched, variable-latency data networks. A jitter buffer is used to
reduce the effects of variable latency introduced by queuing in packet switched
networks, ensuring a continuous data stream over the network.
The P634 receives the synchronization from the SNTP server. This is done using
the IP address of the SNTP server entered into the P634 from the IED
Configurator software.
