Enabling and Disabling Ethernet Services

Introduction

The BMENOC0301/11 Ethernet communications module provides several services. Use the Services page in the Control Expert to enable and disable those services.

Enabling/Disabling Ethernet Services

View the Services for the BMENOC0301/11 module:

Step	Action
1	Open a Control Expert project that includes a BMENOC0301/11 module.
2	Open the DTM Browser (Tools → DTM Browser).
3	In the DTM Browser, find the name that you assigned to the BMENOC0301/11 module..
4	Double-click the name of the BMENOC0301/11 to open the configuration window. NOTE: You can also right-click on the module and scroll to Open to open the configuration window.
5	Select Services in the navigation tree.
6	Enable or disable each feature: Enabled: Scroll to Enabled to enable the service. Disabled: Scroll to Disabled to disable the service.
7	Click a button: Apply: Save changes with the window open. OK: Save changes and close the window.
8	Expand (+) Services in the navigation tree to view the enabled services.

NOTE:

Most services appear in the expanded Services tree only when they are enabled. Services that are always enabled (like SNMP and RSTP) always appear in the navigation tree.
You can configure the settings for any enabled service. If you enable a service that you do not configure, the Control Expert DTM applies the default settings.

Available Services

These Ethernet services are provided by the BMENOC0301/11 Ethernet communications module:

Service	Description	Default
SNMP	serves as an SNMP v1 agent provide trap information to up to two devices configured as SNMP managers NOTE: The SNMP service is enabled by default and cannot be disabled.	enabled
Address Server	Provide IP addressing parameters and operating parameters to other Ethernet devices.	enabled
RSTP	Employ RSTP in combination with other similarly-configured network devices to manage redundant physical connections and create a loop-free logical path that connects network devices.	enabled
Network Time Service	Provide the source time synchronization signal for the PLC controller, which manages an internal clock to maintain this time.	disabled
QoS Tagging	Add DSCP tags to Ethernet packets so that network switches can prioritize the transmission and forwarding of Ethernet packets. NOTE: Before enabling QoS tagging, confirm that devices connected to the Ethernet communication module support QoS tagging.	enabled
Service Port	The system allows connection to a control network through the service port.	enabled

DTM

(device type manager) A DTM is a device driver running on the host PC. It provides a unified structure for accessing device parameters, configuring and operating the devices, and troubleshooting devices. DTMs can range from a simple graphical user interface (GUI) for setting device parameters to a highly sophisticated application capable of performing complex real-time calculations for diagnosis and maintenance purposes. In the context of a DTM, a device can be a communications module or a remote device on the network.
