|
|
|
| correspond to the IP address of the GE- |
|
|
|
| Ethernet port producing the message. It |
|
|
|
| corresponds to the producer ID configured for |

| the CPU producing the data. | Nnn.nnn.nnn.nnn |

| ge_producerId | The default value is typically the same as the | Where nnn are in the |
|
|
| IP address of the producer but the value can | range |
|
|
| be changed and it is possible for one device |
|
|
|
| to have multiple Ethernet interfaces and |
|
|
|
| hence multiple IP addresses. |
|
|
|
| Any change to the producerID must be |
|
|
|
| matched by a similar change in the |
|
|
|
| consumer's configuration. |

|
| Used with the the producerID, to uniquely |
|
|
| ge_exchangeId | identify a packet of EGD data. Thus, this | Integer values >= 1 |

|
| produced data packet with one or more |

| Each produced data packet contains raw | Byte, Bit, Word, |

| If the producer has been configured to |
