• PROPOSAL
• The return value is non-zero unsigned 2-byte wide containing a state, a class and a counter of the binary input. The format is the following:
•
b.0 0: binary input is inactive
1: binary input is active
• b.1-b.7 Counter of the input state changes. Maximum value 0x7F overflows to 0x00.
• b.8-b.14 Class of the binary input
• 0x00 Unused
• 0x01-0x0F Unspecified1-Unspecified15
• 0x10 Window open
• 0x11 Door open
• 0x12 Flood
• 0x13 Presence
• … ToDo
• … 0x7F Reserved
•
b.15 0: value ok
1: error
The recommended visual numeric representation is the c.s.nnn where c is class in decimal radix, s is a state and nnn is counter. Example: 16.0.123 is Closed window while the window was open/closed 123 times.
• FRC 2-byte: FRC return value equals unmodified return value.
