A detailed description of the function profile with all inputs and outputs as well as the configuration parameters can be found at the VDI - Verein der Deutschen Ingineure.
The Web Link is:
Percentage level.:
Level percent. SNVT_switch should be used instead of SNVT_lev_percent, with the exception of network variables that are used to communicate a percentage value and that require the additional resolution provided by SNVT_lev_percent; or for network variable members of functional profiles that are designed primarily for interfacing with SNVT_lev_percent members of other profiles.
Maximum receive time.:
The maximum period of time that may expire with no updates on the associated input network variables before the object goes into heartbeat failure mode. A zero value disables the mechanism.
