Protocol Conversion RTU Application


Asentria has a variety of products that have traditionally been referred to as Remote Terminal Units (RTU). An RTU has been a device that was a part of a communication network that would monitor contact closures, analog measurements, or perhaps do some parsing and evaluation of a legacy protocol. In most cases today, this data is converted into the Simple Network Management Protocol (SNMP), which is a commonly desired alarm format that many devices within a communication network can report on their status.

Asentria units can be used to convert legacy protocols from other devices into more modern alarm formats like SNMP. This allows the SiteBoss to be used to potentially extend the life of older equipment that is currently outside the view of the Network Operation Center (NOC).


ASCII to SNMP

This standard software function allows a SiteBoss unit to collect ASCII text from an attached device, to parse this data, and to create alarms based on user-defined alarm conditions. Complex text analysis is a standard feature within the SiteBoss unit.


XML to SNMP

This software function is available in the scripting ability available in certain SiteBoss units. A SiteBoss can have a script written to query an Extensible Markup Language (XML) document and, based on the results returned from the query, determine if an alarm state exists. If an alarm state does exist, any alarm method is available for notification, including the methods shown under "SNMP Integration". It is also possible that a user might just use this ability to populate an OID within the MIB of the SiteBoss that can be polled by an NMS.

MODBUS to SNMP

This software function is enabled through the use of the scripting language within the SiteBoss unit. The SiteBoss can collect data from a MODBUS device, parse this data, and create alarms based on user-defined alarm conditions. MODBUS is commonly used within sophisticated sensors, and allows us to use power monitors and other specialized sensors that can provide very detailed and accurate data related to their specialized function.


HTML to SNMP

This software function is available in the scripting ability available in certain SiteBoss units. A SiteBoss can have a script written to query a Hypertext Markup Language (HTML) document and, based on the results returned from the query, determine if an alarm state exists. If an alarm state does exist, any alarm method is available for notification, including the methods shown under "SNMP Integration". It is also possible that a user might just use this ability to populate an OID within the MIB of the SiteBoss that can be polled by an NMS.

Scripting to SNMP

This software function is available in the scripting ability available in certain SiteBoss units. These are typically fairly custom applications. This enables the SiteBoss to examine several variables—potentially from different sources—and then make a determination from this combination of variables whether an alarm state exists. If an alarm state does exist, any alarm method is available for notification, including the methods shown under "SNMP Integration". It is also possible that a user might just use this ability to populate an OID within the MIB of the SiteBoss that can be polled by an NMS.
