Description

This table describes the different areas that make up the DTM user interface:

Element	Function
Identification area	Shows the device type name and product name.
Navigation area	The device tree contains: General Settings node CANopen Devices node with a device list that includes a subnode for each device
Application area	Contains parameters, most of them being editable.
Action area	Contains these buttons: OK: Save your changes and close the page. Cancel: Cancel changes. Apply: Save your changes and keep the page open. : Open an online help page. NOTE: Your changes take effect only when they are successfully downloaded from your PC to the CPU and from the CPU to the BMECXM modules and network devices.
Status bar	Shows status information with: Connection state icons Additional icons

Navigation Area: General Settings Node

The General Settings node contains 5 tabs:

Tab	Function
IP/DHCP	These read-only parameters are displayed: IP Settings: IP address, subnet mask, and default gateway Rack and Slot Information: rack ID, slot number, and device name NOTE: These parameters can be changed in Control Expert.
Ethernet IO	These parameters are displayed: EIP Connection Parameters: Task: MAST (by default), FAST, or AUX. RPI T->O: requested packet interval of the consumption connection(1). RPI O->T: requested packet interval of the production connection(1). Hold Up Time: hold-up time and fallback Starting Mode: automatic (by default) or manual
Security	These parameters are displayed: Global Policy: to enforce or unlock security. Services: FTP, HTTP, SNMP and EIP to be enabled/disabled. Access Control: to enable/disable Ethernet access to the EtherNet/IP server.
SNMP	These parameters are displayed: IP Address Managers: IP addresses. Agent: location and contact, and SNMP manager to be enabled/disabled. Community Names: set, get, and trap. Security: authentication failure trap to be enabled/disabled.
NTP	The NTP Client Configuration parameter is displayed: NTP, IP addresses, and polling period.
(1) The refresh period for this connection is in ms (2...2550).

Navigation Area: CANopen Devices Node

When clicking the CANopen Devices node, a Device List tab shows all slave devices with read-only parameters: Address, Device Name, Vendor, Type, and Version.

When expanding (+) the CANopen Devices node and clicking a slave device, the I/O tab is displayed with 2 fields:

Field	Function
IO Structure Name	These parameters are displayed: Structure Name (read-only): name assigned to the device input structure from the imported CANopen configuration Variable Name (editable) NOTE: The variable name is reinitialized when clicking the Default Name button or if the structure name has been changed.
Variables Management	The Import Mode (read-only): displays the automatic option only.

Each slave device contains a Variables subnode.

When expanding (+) a slave device and clicking the Variables subnode, these tabs are displayed, when relevant, with read-only parameters:

Tab	Function
Input	Displays Type, Offset, Name, and Comment columns.
Input(bit)	Displays Offset, Position, Name, and Comment columns.
Output	Displays Type, Offset, Name, and Comment columns.
Output(bit)	Displays Offset, Position, Name, and Comment columns.

NOTE: You cannot add, delete, or edit .

In these tabs, all the bits or bytes from the I/O modules of the CANopen device are displayed.

At the beginning of each row, the data type is visually indicated:

Data types	BOOL	BYTE	INT, UINT, WORD	DINT, UDINT, DWORD	REAL	String
Visual representation

NOTE: Icons are left blank if bits and bytes are unused.

Application Area

When you edit a parameter, Control Expert displays an icon next to the field you are editing and in the navigation tree.

These icons refer to the value of the parameter that is being edited:

Icon	Description
	The entered value is not known. The Apply button does not work until a correct value is entered.
	The entered value is not valid. The Apply button does not work until a valid value is entered.
	This parameter has changed. The Apply button does not work until the value is corrected.

NOTE: You can move the mouse over the icons to display tooltips.

Status Bar

This table shows the connection state icons of the status bar and their functions:

Icon	Element	Function
	Disconnected	The DTM is offline.
	Connected	The DTM is online.
	Connecting	The DTM is connecting.
	Disconnecting	The DTM is disconnecting.
	Communication problem	There are communication errors detected, for example wrong IP address.

This table shows the additional icons of the status bar and their functions:

Icon	Element	Function
	Communication in progress	The DTM communicates with the device.
	Data set	Displays the offline data stored in the DTM.
	Device	Displays the offline data stored in the device itself.
	Summary	Displays the summary state of the data when at least one parameter value has been modified (none by default).

(Device type manager) 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.

(central processing unit) Brain of an industrial manufacturing process, also known as the processor or controller. It automates a process as opposed to relay control systems. CPUs are computers suited to survive the harsh conditions of the industrial environment.

The 32-bit identifier, consisting of both a network address and a host address assigned to a device connected to a TCP/IP network.

The 32-bit value used to hide (or mask) the network portion of the IP address and reveal the host address of a device on a network using the IP protocol.

A gateway device interconnects two different networks, sometimes through different network protocols. When it connects networks based on different protocols, a gateway converts a datagram from one protocol stack into the other. When used to connect two IP-based networks, a gateway (also called a router) has two separate IP addresses, one on each network.

A group of sections and subroutines, executed cyclically or periodically for the MAST task and periodically for the FAST task. A task possesses a level of priority and is linked to inputs and outputs of the controller. These I/O are refreshed in relation to the task. A controller can have several tasks.

(requested packet interval) The time period between cyclic data transmissions requested by the scanner. EtherNet/IP devices publish data at the rate specified by the RPI assigned to them by the scanner, and they receive message requests from the scanner at each RPI.

(target to originator) Refer to originator and target.

(originator to target) Refer to originator and target.

(file transfer protocol) A protocol that copies a file from one host to another over a TCP/IP-based network, such as the Internet. FTP uses a client/server architecture as well as separate control and data connections between the client and server.

(hypertext transfer protocol) A networking protocol for distributed and collaborative information systems. HTTP is the basis of data communication for the Web.

(simple network management protocol) Protocol used in network management systems to monitor network-attached devices. The protocol is part of the Internet protocol suite (IP) as defined by the Internet engineering task force (IETF). It consists of network management guidelines, including an application layer protocol, a database schema, and a set of data objects.

A network communication protocol for industrial automation applications. It combines the standard Internet transmission protocols of TCP/IP and UDP with the application layer common industrial protocol (CIP) to support both high-speed data exchange and industrial control. EtherNet/IP employs electronic data sheets (EDS) to classify each network device and its functionality.

(Network time protocol) Protocol for synchronizing computer system clocks. The protocol uses a jitter buffer to resist the effects of variable latency.

Memory unit that is addressed and modified by a program.

A variable that is a series of ASCII characters.
