Technical Update

LonMark is releasing the latest set of standard device resource files, beta version 13.20, this week.  This new beta set of files includes the latest updates to existing enumerations (plus two new sets: time_source_t & scheduler_status_t) and the following new data types for network variables and configuration properties: 

Container standard network-variable types (SNVTs) as part of a set of requirements for meeting SIL-3 of IEC 61508:

SNVT_safe_1, SNVT_safe_2, SNVT_safe_4, & SNVT_safe_8. 

Two new scalar standard network-variable types for supporting absolute mass flow in kg/h (and pounds/h with format conversion) for HVAC applications:
 

SNVT_mass_flow & SNVT_mass_flow_f. 

SNVTs and SCPTs (standard configuration-property types) supporting the new Simple Scheduler for embedded scheduling applications:

SNVT_time_val_2, SNVT_time_offset, SNVT_sched_exc, & SNVT_sched_status and SCPTs: SCPTscheduleSunday...SCPTscheduleSaturday, SCPToccupancyBehavior, SCPTtimeSource, SCPTscheduleException, SCPTscheduleHoliday, SCPTrandomizationInterval, SCPTsunriseTime, SCPTsunsetTime, SCPTschedulerOptions, & SCPToccupancyThresholds. 

Plus, the new Simple Scheduler profile (SFPTschedulerSimple).
 

Pending field vetting, the new v13.20 beta will become the basis for the official, gold release of v14.00; now underway.
