This identifies the GE device producing

 

 

 

 

 

 

 

 

 

 

 

 

the EGD data. Although in decimal dot

 

 

 

 

 

 

 

 

 

 

 

 

format, it is not an IP address and does

 

 

 

 

 

 

 

 

 

 

 

 

not necessarily 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

Where nnn are in the

 

 

 

 

 

 

 

the IP address of the producer but the

 

 

 

 

 

 

 

value can be changed and it is possible

range 0-255.

 

 

 

 

 

 

 

 

 

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.

 

 

 

 

 

 

 

 

 

 

 

 

This and the producerID uniquely identify

 

 

 

 

 

 

 

 

 

 

 

 

a packet of EGD data. Thus, the

 

 

 

 

 

 

 

 

ge_exchangeId

 

consumer uses these two parameters to

Integer values >= 1

 

 

 

 

update. Any change to the exchangeID

 

 

 

 

 

 

 

must be matched by a similar change in

 

 

 

 

 

 

 

 

 

 

 

 

the consumer's configuration.

 

 

 

 

 

 

 

 

 

 

 

 

Each produced data packet contains raw

 

 

 

 

 

 

 

 

 

 

 

 

packed data.

This keyword is used to tell the driver

Dword, Int , Long

 

 

 

 

 

 

 

how to pack the data into the message.

Float (4 byte IEEE real

 

 

 

 

 

 

 

Thus you can read from a BIT array in

number) or Double (8

Any change to the data type must be

matched by a similar change in the
