2.4.2
Communication Stop during Firmware Update or Configuration
Download
If you want to perform either a firmware update (as a download) or a
configuration download, both via the corresponding Master DTM in
SYCON.net, be aware of the following:
•
Together with the firmware download, an automated reset to the device
is performed that will interrupt all network communication and all
established connections will drop.
•
If you download the configuration during bus operation, the
communication between master and slaves is stopped.
Possible faulty System Operation
•
An unpredictable and unexpected behavior of machines and plant
components may cause personal injury and property damage.
¾
Stop the application program, before starting the firmware update or
before downloading the configuration.
¾
Make sure that your equipment operates under conditions that prevent
personal injury or property damage. All network devices should be
placed in a fail-safe mode, before starting the firmware update or before
downloading a configuration.
Loss of Device Parameters, Overwriting of Firmware
•
Both the firmware download and the configuration download erase the
configuration data base. The firmware download overwrites the existing
firmware in the network device.
¾
To complete the firmware update and to make the device operable
again, re-load the configuration after the firmware update has been
finished.
For devices with Ethernet technology
•
Device parameters that have been saved volatile, e. g. as the
temporarily set IP address parameters, are getting lost during the reset.
¾
In order to prevent loss of configuration data, make sure that your
project configuration data are saved non-volatile, before you initiate a
firmware update or download the configuration.
2.4.3 Mismatching
System
Configuration
Mismatching system configuration loaded into the device could result in
faulty data mapping in the application program and thus unexpected
equipment operation may cause personal injury or damage of equipment.
¾
In the device use only a configuration suitable for the system.
