Configuring A Global Data Exchange For A Producer - GE VersaMax PLC User Manual

6.4 Configuring a Global Data Exchange for a Producer

Parameters
The address that uniquely identifies the CPUE05 as an Ethernet Global Data device across the network.
It is a dotted-decimal number. The default is the same as the IP address of the CPUE05. The default can
Local Producer ID
be changed.
Exchange ID A number that identifies a specific data exchange.
Adapter Name Always 0.0 for CPUE05.
Select whether the data's destination will be a single device (IP address) or one of 32 predefined device
Consumer Type groups (Group ID). Refer to the section,
information. For more information about groups, click the Group Usage button above.
If the Consumer Type above is IP Address, this is the IP address of a single device to receive the
Consumer
exchange. If the Consumer Type is Group ID, this is the group's ID number (1–32). Refer to chapter 13,
Address
Ethernet Communications
Currently fixed at always. Ethernet Global Data will always be sent when the PLC's I/O scan is enabled.
Send Type
It will not be sent when the I/O scan is disabled.
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.
Producer Period
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.
Reply Rate Currently not used.
A data range that identifies the memory location where the status value for the produced exchange will
be placed. Refer to the section,
Status Word
the Status Word address must be unique; it is not automatically assigned the next highest address.
Offset
example:
Status
A list of 1 to100 data ranges that will be sent in the exchange. Data is sent as a contiguous set of bytes.
Exchange Data
Refer to the section,
Ranges
up to 1400 bytes. The list of data ranges to be sent in an exchange specifies:
Offset

86 GFK-1503E
For public disclosure
Each Global Data exchange must be configured in the producer as defined below. The
exchange must also be configured in each consumer, as explained next.
