Need Class Library Info of Custom DLLs from 'SIG Pack Systems AG'

I have an WonderWare Intouch 7.1 scada application which uses several DLLs from 'SIG Pack Systems AG', namely SIG Alarm Manager (sigalm.dll), SIG Event Manager (sigevt.dll), SIG Recipe Manager (sigrcp.dll), SIG web manager (sigweb.dll), SIG Language Manager (siglng.dll).
I am looking for the class library information (as visible with Object browser in VB6.0) for these DLLs. Request to anyone who has used these to help.
