cur-point

Point with support to report a "real-time" current value. By real-time we typically mean freshness within the order of a few seconds or at most a few minutes. For systems with direct I/O the current value is typically driven by the I/O scan rate. For overlay systems which acquire data via a protocol such as BACnet or Modbus then the current value is typically refreshed using polling or subscription over a network. Also see Points chapter.
