Input

Array of dynamic length that is published to the given Destination MAC Address. The data type is specified in the Message Data Type field using the Base Interval Time parameters.

Use Byte Pack blocks to convert to signed values or floating-point numbers. You can pack one double value to a vector of type int8 and length 8.

This block does not have any output ports.

Ethernet Port

Define from which local Ethernet port GOOSE messages should be published. The internal Ethernet interfaces of Speedgoat target machines have for example 'ETH1' as an available port.

Message Data Type

Select one of the data types listed in the dropdown list:

• Int8

  1-byte signed integer.

• Double

  8-byte floating point.

• Quality

  4-byte unsigned integer.

• Boolean

  1 bit.

Base Interval Time

Define the base interval for publishing GOOSE messages. When a value changes, the publishing interval is divided by 10 and then augmented in 2 steps until it reaches the base interval again.

Sample Time

Defines the base sample time at which this driver block gets its sample hit. This parameter can also be set to -1 for inherited sample time. The units are in seconds.

Destination MAC Address

Define the multicast/broadcast MAC address of the GOOSE message. For the purpose of broadcasting use ff:ff:ff:ff:ff:ff.

GOOSE App ID

The GOOSE app ID will be inserted into the published message. This way you can filter the messages when publishing on the same MAC address.

VLAN ID

The VLAN identifier is used to tag a message. The values of 0 and 4095 (0x000 and 0xFFF in hexadecimal) are reserved. All other values may be used as VLAN identifiers, allowing up to 4,094 VLANs.

Refer to this webpage for further information about VLAN parameters: IEE_802.1Q Wiki.

VLAN Priority

The VLAN priority (priority code point (PCP)) sets the priority level of the message.

Refer to this webpage for further information about VLAN parameters: IEE_802.1Q Wiki.
