3 Release and Version Management
ABB continuously enhances the ETL600 system by upgrading hardware, firmware and software.
An ETL600 system release, identified by a release number, is a product of defined functionality
comprising hardware modules, firmware and software.
Firmware and software are identified with version numbers of the form NN.nn., e.g. 5.08 (leading
zeros may be omitted).
Releases are identified by release numbers of the form RR.r, e.g. 3.1 (leading zeros may be
omitted).
Hardware modules are identified with type codes consisting of 4 characters like P7LC, G4AI or
P4LT. Sometimes, a fifth character - the revision index - is appended to identify an upgraded
version of a module. Example: P4LTa is an upgraded version of P4LT; P4LTb would be an
upgraded version of P4LTa and so on.
Note:
4 Compatibility rules
•
Rule Nr. 1:
The modules of an ETL600 terminal and the firmware on these modules must belong to the
same release as given by Table 1.
If an equipment contains modules of different releases, it will generally not work correctly.
•
Rule Nr. 2:
The two ETL600 terminals of a link must belong to the same release.
If this rule is violated, the EOC of the link will generally not work correctly. Corresponding
warning messages will be generated by HMI600.
•
Rule Nr. 3:
The HMI600 software must have full or restricted compatibility to the ETL600 terminals being
connected to.
The term "restricted compatibility" is used when the functionality has been changed between
releases as long as the HMI600 program can handle these changes in a reasonable way.

The information content of type codes in case of modules containing firmware
depends on the possibility to download firmware from HMI600 into the module:
• If for a component firmware download is not possible, the type code of that
component identifies the hardware including the firmware version.
Example: Microcontroller on P4LT/P4LU
• If for a module firmware download is possible, the type code of that module
identifies the hardware excluding the firmware version. The download files
for the firmware of such modules are included on the HMI600 Software &
Documentation CD.
Example: O4LE
