ge_producerId
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.
The default value is typically the same as
the IP address of the producer but the
value can 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.
Nnn.nnn.nnn.nnn
Where nnn are in the
range 0-255.
ge_exchangeId
This and the producerID uniquely identify
a packet of EGD data. Thus, the
consumer uses these two parameters to
update. Any change to the exchangeID
must be matched by a similar change in
the consumer's configuration.
Integer values >= 1
ge_data_type
Each produced data packet contains raw
packed data.
This keyword is used to tell the driver
how to pack the data into the message.
Thus you can read from a BIT array in
the FieldServer but send the data as
words for storage in %R (register
memory) in the GE-PLC.
Any change to the data type must be
matched by a similar change in the
consumer's configuration.
Byte, Bit, Word,
Dword, Int , Long
Float (4 byte IEEE real
number) or Double (8
byte IEEE real
number).

Scan_Interval
Rate at which data is produced. This is the equivalent of
the producer interval.
