Connecting SNMP to DeviceNet

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 DeviceNet 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 DeviceNet 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 DeviceNet 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

DeviceNet

The FieldServer DeviceNet Master X30 Adapter driver can be used to emulate a single Master Scanner station on a DeviceNet network. The DeviceNet adapter is implemented as an ODVA profile 12 communications adapter. Standard DeviceNet baud rates of 125K, 250K and 500kbit/s are supported. DeviceNet Master Scanner can open an I/O connection of up to 512 Bytes in each direction to the DeviceNet Slaves,


The FieldServer DeviceNet Slave X30 Adapter driver can be used to emulate a single slave station on a DeviceNet network. The DeviceNet adapter is implemented as an ODVA profile 12 communications adapter and acts as a group 2 only server on the DeviceNet Network. Standard DeviceNet baud rates of 125K, 250K and 500kbit/s are supported. DeviceNet masters/scanners can open an I/O connection of up to 512 Bytes in each direction to the FieldServer


DeviceNet is a communication protocol used in the automation industry to interconnect control devices for data exchange. It uses Controller Area Network as the backbone technology and defines an application layer to cover a range of device profiles. Typical applications include information exchange, safety devices, and large I/O control networks.


DeviceNet was originally developed by American company Allen-Bradley (now owned by Rockwell Automation). It is layered on top of the CAN (Controller Area Network) protocol, developed by Bosch. In order to promote the use of DeviceNet worldwide, Rockwell Automation has adopted the "open" concept and decided to share the technology to third party vendors. Hence, it is now managed by the Open DeviceNet Vendors Association (ODVA), an independent organization located in North America. ODVA maintains specifications of DeviceNet and oversees advances to DeviceNet. In addition, ODVA ensures compliance to DeviceNet standards by providing conformance testing and vendor conformity.
