6.5 Configuring a Global Data Exchange for a
Consumer
To receive a Global Data Exchange, configure the following information:
Parameters Description
Local
Producer ID
Exchange ID
Ethernet Configuration
Description
The scheduled repetition period for sending the data on the network. The
range is 10–3,600,000 milliseconds (10 milliseconds to 1 hour). The default
is 200 milliseconds. Round this value to the nearest 10 milliseconds before
you enter it. The producer period has a resolution of 10 milliseconds. If you
enter a value such as 12 milliseconds, the actual producer period will be
rounded up to 20 milliseconds.
For easier troubleshooting and efficient network usage, set the Producer
Period to the same value as the Consumer Period. Do not produce data faster
than is required by your application. For example, it is usually not useful to
produce data faster than the scan time of the producer or consumer PLCs.
This reduces the load on the network and on the devices, providing capacity
for other transfers.
Currently not used.
A data range that identifies the memory location where the status value for
the produced exchange will be placed. See "Checking the Status of an
Exchange" in chapter 13 for details. Note that the Status Word address must
be unique; it is not automatically assigned the next highest address.

A list of 1 to100 data ranges that will be sent in the exchange. Data is sent as
a contiguous set of bytes. See "Checking the Status of an Ethernet Global
Data Exchange" in chapter 13 for details. The total size can be up to 1400
bytes. The list of data ranges to be sent in an exchange specifies:

The address that uniquely identifies the CPUE05 as an Ethernet Global Data
device across the network. The default is the same as the IP address of the
CPUE05. The default can be changed.
A number that identifies that specific data exchange. It must match the
Exchange ID specified in the produced exchange (in the sending device).
