9 Data Management
The control unit contains a number of parameters which indicate the control unit type and
the firmware version.
9.1 Serial Number of the Control Unit
Each individual control unit is uniquely identified by a serial number. The first 4 digits
indicate the production year and the shipping month. The remaining digits consist of the
sequential production number. The serial number can be seen on the
HEINZMANN
nameplate and in the following parameters:
3844 SerialDate
Year and month of manufacture
3845 SerialNumber
Sequential production number
9.2 Identification of the Control Unit
The application-related functionality of a control unit is uniquely defined by the firmware
which only runs on exactly one particular hardware type.
3840 HardwareVersion
Version number of the control unit hardware
3841 AddHardwareVersion
Version number for hardware modification
3842 SoftwareVersion
Version number of the control unit firmware
3843 BootSoftwareVersion
Version number of the bootloader software
The software version consists of an unique two- to four-digit customer number x defined
by
HEINZMANN, a one- to two-digit variant number y and a two-digit change index z.
xx.y.zz or xxxx.yy.zz
DcDesk 2000 and hand programmer only allow the customer to access control units which
contain the HEINZMANN basic software 00.y.zz or a custom firmware xx.y.zz with his
own customer number x. The variants y define different firmware, e.g. for different
applications of a manufacturer. Each variant can exist in different change levels z by
means of software enhancements; the next higher change index always incorporates the
next lower change index and supersedes it (
2.2 Firmware).
