Processor Time
Make sure when configuring tasks, that there is sufficient processor time
available for all processes.
Network Load
The controller's CPU processes both the PLC program and network traffic.
ETHERNET communication demands that each received telegram is processed,
regardless of whether it is intended for the controller or not.
A significant reduction of the network load can be achieved by using switches
instead of hubs.
There is no measure against broadcast telegrams that can be used on the
controller, however. These can only be curtailed by the sender, or blocked with
configurable switches that have a broadcast limitation. A network monitor such as
"wireshark" (www.wireshark.com) provides an overview of the current load in your
network.
