You have two devices in two different buildings on two completely different networks, one that uses the SNMP(std) protocol to communicate, while the other one talks GE SRTP 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(std) protocol and the GE SRTP 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(std) data to GE SRTP data.
It's a simple solution to a common problem that we can help you with.
Description: The FieldServer SNMP - STD driver provides an SNMP v.1 client and agent (server). 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. The FieldServer SNMP Gateway provides a generic MIB fiel that sets out the OID's structures to use. The FieldServer Enterprise ID is 6347. A selection of standard MIB-2 OID's are supported to allow interaction with popular Network Management packages. Acting as an SNMP agent (server), the SNMP-STD driver makes allows SMCP Get, GetNext(walk) and Set commands to access Data Arrays using the Integer type. The SNMP v1 protocol does not make provisioin for Floats. The SNMP - STD driver can also send SNMP traps. FieldServer's standard MIB file also provides the structures for SNMP traps. The following SNMP data types are currently supported: INTEGER OCTET_STRING TIMER_TICKS More information, Driver Data Sheet
SRTP=Service Request Transfer Protocol
he GE-SRTP driver allows the FieldServer to transfer data to and from devices over Ethernet using GE-SRTP Driver protocol. Almost all GE automation equipment supports the GE-SRTP protocol when equipped with an Ethernet Port.
The FieldServer can emulate either a Server or Client. The driver, acting as a Client, is capable of reading and writing system memory of any number of remote SRTP capable devices. The FieldServer can scale word data ( %AQ, %AI, %R ) when acting as a Client.
When configured to act as an SRTP Server, the driver accepts system messages which write to system memory and responds to read requests. When acting as a Server the driver is always at privilege level 4 (allowing it to be written and read).
The driver cannot emulate a Client and Server simultaneously on the same connection to the same IP address.
