Connecting SNMP to MetOne

You have two devices in two different buildings on two completely different networks, one that uses the SNMP protocol to communicate, while the other one talks MetOne Particle Counters protocol and they need to talk to each other. What do you do?

A FieldServer is a protocol converter or gateway that can communicate in many different protocols and physical layers including SNMP protocol and the MetOne Particle Counters protocol. The Fieldserver acts as a middle man between the two devices. It reads data from one device, stores it internally and makes it available to the 2nd device using another protocol. This is how the FieldServer converts SNMP data to MetOne Particle Counters data.

It's a simple solution to a common problem that we can help you with.

SNMP

The SNMP driver allows the FieldServer to transfer data to and from devices over Ethernet using the SNMP version 1 protocol. The FieldServer can emulate either a Server (SNMP Agent) or Client.


The Client can be configured to read values specified by their SNMP Object Identifiers (OIDís), which are defined in the MIB file (Management Information Base) of the target device. When acting as an SNMP Agent (Server), the driver makes the contents of specified integer data arrays available to any SNMP Client. The FieldServer MIB file sets out the OIDís to use.


The current version of the driver can send and receive SNMP traps. The following SNMP data types are currently supported:


∑ INTEGER ∑ OCTET_STREAM ∑ TIMER_TICKS ∑ STRING

MetOne Particle Counters

The MetOne Particle Counter Serial driver allows the FieldServer to transfer data to and from devices over RS-232 or RS-485 using MetOne Particle Counter Serial protocol.


The primary purpose of the driver is to obtain the current particle counts, but it does allow for limited control and configuration of some counter parameters. While the driver provides Client and Server emulation, the Server side of the driver is intended to support FieldServerís Quality Assurance program and is not intended to provide complete emulation of a MetOne Counter. When configured as a Client the driver can start/stop a unit from sampling, change its mode, set and get sample and hold times, startup or standby a unit and retrieve its current sample value. Whenever the driver stores a sample value, it will also store a timestamp of when the record was obtained.
