(message by IssueLinks)PPS is not yet supported. I will update documentation and try to find a way to detect if the system is PPS bus.
For support, if you know the relevant parameters for PPS-bus please provide and I could add support.
Please make a ticket for the parameters on python bsblan lib repo
