Fieldbus Controller
Fieldbus Controller 750-872/020-000
Ethernet
Under the Ethernet link, you can view and change settings for the data
transmission rate and the bandwidth limitation for the Ethernet transmission.
These should be changed however only in completely special cases.
Note
A faulty configuration of the transmission mode may result in a link loss
condition, a poor network performance or a faulty behavior of the
coupler/controller.
Both the controller and its link partner must be configured for the same
transmission mode to ensure reliable and fast communication using the
Telecontrol controller, which means they must operate either in (default)
autonegotiation mode or full or half duplex mode with 10/100Mbit static
transmission rate.
Further Information
Please find detailed information on how to cofigure the transmission mode in
the "Fieldbus Communication"/"ETHERNET"/
"Network Architecture – Principles and Regulations "/"Transmission Mode".
The bandwidth limitation can be activated or deactivated. The "Active time
(ms)" is thereby the Watchdog time, after which the interrupts become
disabled, whereby telegrams can be lost. The timer is triggered by a task in the
system. The priority of the task is determined by the parameter mode:
Mode 1: Only the internal bus is held by to run.
Mode 2: The internal bus and the CPU of the controller are held by to run.
Mode 3: All tasks begin to run.
