Firmware updates
Firmware updates should only be installed when they can eliminate existing bugs in the firm-
ware in the device or contain new features.
The firmware of the control panel (HMI), of the communication unit (KE) and the digital controller (DR), if necessary,
is updated via the rear side USB port. For this the software
EA Power Control is needed which is included with the
device or available as download from our website together with the firmware update, or upon request.
However, be advised not to install updates promptly. Every update includes the risk of an inoperable device or
system. We recommend to install updates only if...
•
an imminent problem with your device can directly be solved, especially if we suggested to install an update
during a support case
•
a new feature has been added which you definitely want to use. In this case, the full responsibility is transferred
to you.
Following also applies in connection with firmware updates:
•
Simple changes in firmwares can have crucial effects on the application the devices are use in. We thus recom-
mend to study the list of changes in the firmware history very thoroughly.
•
Newly implemented features may require an updated documentation (user manual and/or programming guide,
as well as LabView VIs), which is often delivered only later, sometimes significantly later
