HV Power recommends that all networks have their contractors and consultants keep in-step with the same DIGSI software versions. This eliminates the risk of receiving a setting file that you can’t open, as the prior person in the ‘chain’ had a more up-to-date DIGSI version, or a technician can’t load a new setting to a relay, as the consultant was using a later version, and so on.
Rather than undertaking updates as each new DIGSI version comes out, most of our customers ‘lock in’ a version for a period of time. It is therefore critical for contractors and consultants to know the requirements of each utility they support – i.e. what version of DIGSI they use.
From time to time a ‘hotfix’ is released. This is to fix a bug in the software without having to issue a whole new version. Typically a hotfix sorts out a critical issue and does not affect the setting data structure – thus having different hotfixes may not be an issue. A hotfix is normally applied ‘on top’ of an installed version of DIGSI. Later versions of a hotfix also include earlier versions (i.e. HF03 includes HF01 & HF02 etc). A hotfix is always specific to a given version of DIGSI. Occasionally, Siemens release a new DIGSI installer that also includes the hotfixes – saving time for new installs. In some cases the term ‘Service Pack’ is also used (e.g. SP1).
- Latest version of DIGSI 5 = Version 7.8
- Latest hotfix = HF03
- For those customers still ‘locked into’ Version 7.5, its latest hotfix is HF04
- Latest version of DIGSI 4 = Version 4.93
- Latest Service Pack = SP1
- 4.93 is being used in NZ by new customers (and those with 7SC80 hardware to allow support of its support flexible protocol mapping).
For existing customers, such as most utilities, DIGSI 4.91 remains our recommended version. DIGSI 4.91 has Service Pack 1 released.
IEC 61850 System Configurator:
DIGSI 4 and DIGSI 5 both use the same IEC 61850 System Configurator with the most current version being 5.8 with Hotfix 1. In this case the Hotfix is not available as a separate file, so the full System Configurator V7.80+HF1 should be downloaded and reinstalled.
The various files and hotfixes can be found on HV Power’s password-protected Service Provider webpage. Contact us if you need access details.
