Chapter 4. Configuration
A variable is automatically created for the required Status variable. This variable contains the local exchange
status that is returned to the PLC logic application. The exchange status is not part of the produced exchange
data and is not available to the network.
Configuring an Ethernet Global Data Exchange for a Consumer
The exchange details are defined in the Properties for each Consumed exchange.
When an individual consumed exchange is selected, the Properties inspector window permits user
configuration of the following information:
Name A name assigned for this exchange. Defaults to "ConsExchX" where X is a sequential
number.
Producer ID
The PLC producing the exchange. This value, conventionally expressed as a dotted-
decimal number, uniquely identifies the Ethernet Global Data device across the network.
Group ID Used only if the produced exchange has been configured with a Destination Type of
Group ID. This Group ID (1-32) must match that of the producer.
Exchange ID Identifies a specific data exchange to be received by the consuming device. It must
match the Exchange ID specified in the produced exchange.
Adapter Name
The specific Ethernet Interface, identified by its rack and slot location within the
consuming PLC.
Consumed
Not used in PACSystems. (Always displayed as 200 milliseconds; not editable.)
Period
Update Timeout A value in the range 0 to 3,600,000 milliseconds (1 hour). The Ethernet Interface will
declare a refresh error if the first or subsequent packet of data does not arrive within this
time. The Update Timeout should be at least double the producer period, and should
allow for transient network delays. The default is 0 indicates no timeout. Resolution is in
2ms increments.
Run Mode Store
When set to True, allows you to modify or delete this exchange and store the changes
Enabled while in Run mode. You can add exchanges in Run mode regardless of the setting of this
parameter.
It is recommended that you keep this parameter at its default setting, False, unless your
application has a specific need to modify this exchange in Run mode.
