Note: The Consumption Timeout is set at twice the Production Period on the other consuming RX3i
CPE310 / RSTi-EP CPE100/CPE115 node. For example, for A, the Production Period for all the
Producer exchanges is set to 500ms. This indicates that the Consumption Timeout for all the
consumer exchanges on the consuming node is set to 1000ms (twice the production period).
The following are important points to be considered when configuring EGD exchanges on Embedded
Ethernet Interface.
1. The recommended values in the given table should be used in conjunction with the
recommended limit value for ����������������������������������������������_% as per the watchdog time and
sweep load of the application.
2. EGD Consumption and Production below 20ms are not recommended for Embedded Ethernet
Interface on with RX3i CPE302/CPE305/CPE310, RSTi-EP CPE100/CPE115.
3. It is advisable to limit the number of EGD exchanges or EGD load on Embedded Ethernet
Interface of the RX3i CPE302/CPE305/CPE310, RSTi-EP CPE100/CPE115 and use higher periods
while defining the system and configuration, and consider the sweep load for minimizing EGD
sweep impact.
Constant Sweep - EGD on RX3i CPE302/CPE305/CPE310 and RSTi-EP CPE100/CPE115 Embedded
Ethernet Interface
The EGD on Embedded Ethernet Interface can be treated as interrupt blocks. Therefore, EGD exchanges
with Constant sweep may cause sweep overruns and should be avoided. It is also recommended that
the Production period for Producer exchanges be set to multiples (3 and above) of the Constant sweep
time set to avoid stale data being produced by the RX3i CPE302/CPE305/CPE310 and RSTi-EP
CPE100/CPE115 system on Embedded Ethernet Interface. Some of the factors affecting the Constant
sweep overruns with EGD on Embedded Ethernet Interface are Constant sweep time, No of Exchanges,
Production period, and Exchange data size.
The Constant sweep with EGD exchanges configured on Embedded Ethernet Interface and timed or I/O
interrupts will also cause constant sweep overruns and are not recommended.
