Computer Performance/Processor Time
The I/O-IPC is based on a real-time operating system. This means that high-
priority processes (e.g., PLC program) will interrupt or block lower priority
processes. The Web server responsible for Web visualization is among these
lower priority processes.
Processor Time
Make sure when configuring tasks that there is sufficient processor time available
for all processes.
Network Load
The CPU of the I/O-IPC is responsible for the processing of both the PLC
program and network traffic. ETHERNET communication demands that each
received telegram is processed, regardless of whether it is intended for the I/O-
IPC 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 I/O-IPC,
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.
