Option K90 / 91 (Control Unit CU320)

A CU320 Control Unit which is capable of performing communication and open-loop/closed-loop control functions can
be assigned to Line Modules and Motor Modules (incl. Booksize Cabinet Kits) with option K90 and K91 respectively.
The current firmware version including license is stored on the CompactFlash card.
The CompactFlash card for option K90 does not include a performance expansion. The computing capacity
requirement increases in proportion to the number of connected modules and system components and in relation to
the dynamic response required. The full computing capacity of the CU320 Control Unit is available only with
performance expansion 1.
Performance expansion 1 is included with option K91 which supports wider combinations of equipment (see section
"Dimensioning and selection information").
The performance expansion is supplied in the form of a license which is stored in the factory on the CompactFlash
card as a license code. The expansion can also be enabled on-site, for example, if the performance expansions
required are not known when the order is placed. The serial number of the CompactFlash card and the order number
of the firmware option to be enabled are required for this purpose. With this information, the relevant license code can
be purchased from a license database and the firmware option enabled.
The license code is only valid for the CompactFlash card declared and cannot be transferred to other CompactFlash
cards.
The firmware version is encoded in the order number of the CompactFlash card supplied. This can be found on the
CompactFlash card.
The firmware version is encoded as follows in the order number:
Order No.:
Firmware version 1
2
3
4
Version .1
.2
.3
.4
Without performance expansion
With performance expansion 1
