9.2 Updating the modules
After installing the modules and applying the voltage to the central unit, ibaPQU-S rec-
ognizes the modules and checks the software version.
ibaPQU-S has a so-
called “overall release version”. This version contains the current
software version of the central unit as well as the software versions of the modules.
When the software version of a module does not match the “overall release version” of
the central unit, ibaPQU-S will run an automatic upgrade or downgrade of the module.
Afterwards, the module is ready for use.
Important note
After the update, ibaPQU-S will perform a restart. This can take up to 5 minutes.
Once the green system LED L1 is flashing regularly and the LEDs L5 … L8 are all off,
the device is ready again.
