Command: Configure the Local Gateway

COM Port

Serial port on the device, for example for data exchange according to the RS232 standard on a COM port intended for this purpose

Possible configuration settings:

Name: Symbolic only

Port: Physical serial port which is used for this interface, for example COM 5 on a Windows computer

Baudrate: 2400, 4800, 9600, 19200, 38400, 57600, 115200

Activate auto addressing: (default = )

The Local address setting is evaluated. Both devices, which communicate via the serial port, will independently negotiate their addresses before they begin exchanging messages. If the addresses of both devices are the same, then they are negotiated again. This setting is useful when the local addresses cannot be set explicitly, for example for devices which are physically separated.

Local address: Evaluated only when Enable auto addressing is activated

Default = actual value for port

Shared Memory

Shared memory driver

Possible settings:

Name: Symbolic name (has no function)

Forced address: Default = -1 (= no forced address)

Example: 42 means that the driver has to use the fixed address defined here and that addresses are assigned freely in the range 0–255. This setting can be useful when more than one shared memory driver is activated in the configuration.

Ethernet UDP/IP

Ethernet interface for data exchange according to the "User Datagram Protocol"

Possible settings:

Name: Symbolic, unique name (has no influence on the function)

Port index: Port number for the communication

Port indices are in the range 0–3.

They are mapped to the following Ethernet port: 1740–1743.

IP address: Default = 127.0.0.1

This setting can be useful to explicitly set an interface when the device has multiple network interfaces.

Example: 127.0.0.1 stands for some local network interface, also known as localhost. Every other address (for example, 10.27.7.72) represents a real IP address which has to be available on the device.

Network mask: Default = 255.255.255.0

Example: 255.255.252.0

This setting can be useful to explicitly set an interface when the device has multiple network interfaces.

PPP address: Default = 127.0.0.1

Example: 10.13.42.240

Establishes a logical point-to-point connection between the UDP interface and the node named with the address specified here

Causes the UDP interface to communicate exclusively with this node and no broadcasts to be sent in the network

Ethernet TCP/IP

Ethernet interface for data exchange according to the "Transmission Control Protocol"

Possible settings:

Name, Port, IP address: See Ethernet UDP/IP above

Inactivity timeout: Default = 0

This setting defines the time span (in seconds) after which the TCP connections are closed when data is no longer exchanged.

CAN Client (legacy)

Name: Symbolic, unique name (has no influence on the function)

Network ID: Network ID (0...255) of the CAN interface, which should be used for communication.

Node ID: CANopen node ID, which is used for communication. Make sure that there is no node ID conflict.

Enable block transfer: TRUE: Block transfer should be used (default setting)

Baudrate (kbit/s): Baud rate for communication

CAN driver: CAN driver component which should be included in the component list.

Descriptions of the settings can also be found directly in the dialog.

USB Port

Name: Symbolic, unique name (has no influence on the function)

A description for the other settings can be found directly in the dialog.

CAN

For controllers version 3.5.21.0 and higher, this interface should be used instead of CAN-Client (legacy).

Both transfer layers – CAN and CAN FD – are possible. CAN FD allows for a higher data throughput and faster transfer.

Name: Symbolic, unique name (has no influence on the function)

[GLOBAL] Task priority: Global setting for all CAN interfaces. This setting defines the priority for the communication task (default value: '95'; highest priority).

Address: Unique ISO-TP address (0...255) used by the CAN block driver.

Functional Address (Broadcast): Unique functional ISO-TP address used for broadcast messages (0...255, default value: 255).

Network ID: Network ID (0...255) of the CAN interface, which should be used for communication.

CAN FD:

If you set TRUE, then all devices in the network must support CAN FD. If there exist devices in the network which do not support CAN FD, then you should consider using the additional setting Adaptive FD.

Adaptive FD:

This mode can be enabled only when the CAN FD mode is enabled. It can be used for compatibility with classic CAN networks. As long as no CAN FD message is received, the gateway communicates via classic CAN. It automatically switches to the faster FD mode when at least one FD message is received. In order to switch back to classic CAN, the gateway must be restarted.

Baudrate (kbit/s): Baud rate for communication

Data Baudrate (kbit/s): Baud rate for CAN FD communication Used only when CAN FD mode is enabled.

Message Limit: Optional setting to limit the maximum number of messages which are sent consecutively. Default value: 0

CAN driver: CAN driver component which should be included in the component list.

Descriptions of the settings can also be found directly in the dialog.
