MIB Subtree Description

Transparent Factory Ethernet Subtree

This topic details some of the objects in the Schneider private MIB tree. The transparentFactoryEthernet(1) subtree defines groups that support the TFE services and devices:

Service	Subtree Definition
switch(1)	the brand of switches labeled
port502Messaging(2)	objects for managing explicit client/server communications to support applications (for example, HMI, SCADA, or programming tools)
ioScanning(3)	objects for managing I/O device communications that use the I/O Scanner with the Modbus/TCP protocol
globalData(4)	objects for managing the application coordination service using a publish/subscribe protocol
web(5)	objects for managing the activity of the embedded Web servers
addressServer(6)	objects for managing the activity of the BOOTP or DHCP servers
equipmentProfile(7)	objects for each device type in Transparent Factory Ethernet product portfolio
timeManagement(8) (NTP)	objects for managing the UTC time stamp service
email(9) (SMTP)	objects for managing the email service
tfeMibVersion(255)	the version of the Schneider TFE MIB supported by the product

NOTE: All listed services are not available on all communications modules. Refer to the available services for your module.

When devices are added to the Schneider catalog, the private MIB is extended in the following manner:

If needed, a Transparent Factory communication-service object is added for the new device in the subtree that corresponds to equipmentProfile(7). This subtree can hold as many objects as are required.
If needed, a new branch is added at the same level as transparentFactoryEthernet(1). This subtree is created for product-specific objects.

When a new device is added to the catalog a corresponding object description is created in the ASN.1 format. The ASN.1 file(s) are then given to producers of SNMP manager software for inclusion in their products.
