4.23.22.7 Use with POWERLINK bus controllers
When this module is connected to the expandable POWERLINK bus controller, the amount of cyclic data is limited
by the POWERLINK frame to 1488 bytes in each direction (input and output).
When using multiple IF10xx-1 interfaces or other X2X modules with a POWERLINK bus controller, the 1488 bytes
are divided between all connected modules.
4.23.22.7.1 Operating netX modules with the X20BC1083 bus controller
The following must be taken into account to operate netX modules with the bus controller without problems:
•
A minimum revision ≥E0 is required for the bus controller.
•
NetX modules can only be operated with POWERLINK V2. V1 is not permitted.
4.23.22.8 Firmware
This module comes with preinstalled firmware. The firmware is a component of Automation Studio. The module
is automatically updated to this version.
To update the firmware included in Automation Studio, the hardware must be upgraded (see "Project manage-
ment" / "Automation Studio upgrade" in the help system).
4.23.22.9 Recognizing an invalid connection
All cyclic data is set to zero in the event of an invalid connection between the master and slave.
An invalid connection may be caused by the following:
•
No connection between the master and the slave
•
Interface card initialization is not yet complete.
•
The master is in error mode.
•
Data is marked as invalid (IOPS = Bad).
It cannot be determined whether the data is valid or invalid based on the transmitted data. In order to be able
to reliably recognize an invalid connection, it is necessary to evaluate the master's IOPS data additionally in the
application.
Forwarding IOPS data to the application can be enabled via the interface card's DTM ("I/O state information" in AS).
