Appendix F: SNMP Requests, Objects and Security
Previously configured I/O and Registers, as well as some some simple network parameters can be
retrieved from the X-600M using Simple Network Management Protocol (SNMP). The states of the
relays can also be changed through SNMP requests. For most cases, using SNMP is as having the X-
600M generate an Management Information Bases (MIB) file and loading this file into the SNMP
manager software.
The X-600M is different than most other SNMP-enabled devices. Since the X-600M is highly
configurable, the MIB associated with it will change depending on the configuration. It is recommended
to configure the X-600M in its entirety before attempting to use SNMP to access it. Once configured, the
X-600M can generate an MIB file for use with SNMP management software that contains all of the I/Os,
Registers, and Events found on the X-600M. To generate an MIB file, go to the
Network > Advance
Network > SNMP menu tab and click on the button labeled Generate and Download MIB File . The
result will be a MIB file downloaded to the local computer called X600M.mib.
Once the X600M.mib file is generated, load this file into the SNMP management software. The I/O of the
X-600M will fall under the object id .1.3.6.1.4.1.30586.20
(iso.org.dod.internet.private.enterprises.xytronix.x600m).
Assuming the SNMP software has been configured correctly to connect to the address assigned to the
X-600M, and that the security settings have also be configured to match those of the X-600M,
performing an SNMPWALK operation on this object id will return the current status of all of the I/Os,
Registers, and Events that have been configured on the X-600M.
SECURITY
The X-600M supports SNMP version 3, which introduces security enhancements over the previous two
versions. To configure the type of security to use, go the
Network > Advanced Network > SNMP menu
tab. You should choose an authentication protocol and privacy protocol that the SNMP management
software understands. Selecting
None for both fields will disable all security and essential revert back to
SNMP version 1. With no security set, the authentication password will be used for both the read and
write community strings. By default the username is “
snmpuser ” and can be changed in the SNMP setup
page. Also, the Context Name will be left blank in the SNMP management software.
TRAPS
The X-600M can send SNMP messages when an input or relay changes state, when a particular sensor
value is reached or when the supply voltage is out of the desired range. To send a trap, add an Action on
the
Control/Logic > Actions setup page. Choose the event to monitor and select Send SNMP Trap as
the action type. Finally, select the I/O to use as the object of the trap. The current value of this I/O will be
sent with the trap.
Note: The X-600M will send all traps using the SNMP V2c format for sending traps, and are generally
referred to as notifications instead of traps.
