Configuring Ethernet Global Data
VersaMax CPU IC200CPUE05 can be configured for up to 32 Ethernet Global Data exchanges
(any combination of produced and consumed). (See "Ethernet Global Data" in chapter 13
for a discussion of this feature).
Configuration defines both the content of an exchange, its data ranges, and
its operational characteristics. Each Ethernet Global Data produced, or consumed exchange
must be configured individually for each PLC.
You can configure:
•
Up to 1200 data ranges for all Ethernet Global Data exchanges.
•
Up to 100 data ranges per exchange.
•
A data length of 1 byte to 1400 bytes per exchange. The total size of an exchange is the
sum of the lengths of all of the data ranges configured for that exchange.
Different exchanges may have different data ranges. Multiple exchanges can also share
some or all of the same data ranges even if the exchanges are produced at different rates.
Note:
The Ethernet Global Data configuration screens are reached via the rack configuration (not
the CPU configuration).
6.3.1
Before You Configure EGD Exchanges
Before configuring Ethernet Global Data exchanges, you will need to collect information
about the PLCs that will be exchanging the data. Note that this information will be needed
for each PLC's configuration. See chapter 13 Ethernet Communications for details.
Ethernet Configuration
Description
The beginning reference for 10 bytes of Ethernet status data. The content of
this data is described in chapter 13, "Checking the Status of the Ethernet
Interface."
The Status address can be assigned to %I, %Q, %R, %AI or %AQ memory. The
default value is the next available %I address.
Note
: Do not use the 10 bytes assigned to the Status bits for other purposes or
your data will be overwritten.
This value is automatically set to either 80 bits (for %I and %Q Status address
locations) or 5 words (for %R, %AI, and %AQ Status address locations).
IP addresses of up to 3 NTP time servers used to synchronize timestamps in
produced Ethernet Global Data exchanges. If no NTP time servers are
configured here, the Ethernet interface is initialized from the clock in the CPU
instead. See "Timestamping of Ethernet Global Data Exchanges" in chapter 13
for more information.
previous versions only.)
The programming software will not permit consumed exchanges to share data ranges.
