SNMP (std)
The SNMP-STD driver allows the FieldServer to transfer data to and from devices over Ethernet using the SNMP Version V1 or V2c protocol. The FieldServer can emulate a Server (SNMP Agent) or Client (NMS Network Management Station).
The FieldServer provides a generic MIB (Management Information Base) file that sets out the OID (Object Identifiers) structure. The FieldServer Enterprise ID is 6347. A selection of standard MIB-2 OID’s are supported to allow interaction with popular Network Management packages.
When configured as an SNMP Agent (Server) the SNMP-STD driver allows SNMP Get, GetNext (walk) and Set commands to access Data Arrays using the Integer type. The SNMP v1 protocol does not make provision for Floats.
The SNMP-STD driver can send SNMP traps. The structure for SNMP Traps is provided in the FieldServer’s generic MIB file.
The FieldServer also supports custom MIBs and the automatic generation of the MIB file. It supports setting a custom enterprise ID, object names and custom traps or informs. In custom configurations the FieldServer supports various data types as specified in Section 6.1 of the Manual.
When configured as a Client, the FieldServer can read objects from the Server using Get, GetNext (walk) or GetBulk commands. The GetBulk command is very useful to transfer large amounts of data. The FieldServer can update objects in Agent using the Set command.
The FieldServer can accept any trap or inform as long as all the objects in the message are encoded with a full OID.
The Client side of the driver is considered as a custom configuration.
M-Bus
The M-Bus driver allows the FieldServer to transfer data to and from devices using M-Bus protocol. The fieldbus connection is included with the FieldServer. The FieldServer can emulate either a Slave or a Master.
The M-Bus QuickServer Gateway is configurable to act as both a Master and a Slave M-Bus device. As
an M-Bus Master the number of devices supported is limited to 64 devices since the FieldServer provides
power to the M-Bus. The M-Bus Master interrogates the Slave devices as the gateway acts as a Master.
It will request information from the Slave devices and receive and process only the expected responses.
As an M-Bus Slave the maximum number of devices is limited to the M-Bus standard of 250. The
Gateway will act as a Slave and will respond only to requests from M-Bus Master devices.
