Discrete Eingänge; Status Indicators; Input Parameter - Kipp & Zonen SMP serie Bedienungsanleitung

.
Erklärung der erhaltenen Bytes:
01 = MODBUS address
04 = read input registers
10 = number of received data bytes
00 01 = operational mode (mode 1)
00 00 = status flags (none)
00 00 = scale factor = 0 = 1x
03 E5 = 997 decimal = sensor 1 data in W/m²
03 E5 = 997 decimal = raw sensor 1 data in W/m²
00 00 = 0 = standard deviation sensor 1
00 F8 = 248 = 24.8 °C.
00 EA = 234 = 23.4 Volt
66 12 = MODBUS checksum (CRC16)
A.6 Discrete Eingänge
Ein "Discrete" Eingang kann wahr oder falsch sein. Er kann nur gelesen werden, während für ein "Coil" auch Schreibzugri besteht.

R/W Def. Mode Description
R 0 All Always false (for testing only)
R 1 All Always true (for testing only)
R * All Void signal, 1=unstable signal, temperature too low or too high
R * All Overflow, signal out of range
R * All Underflow signal out of range
R * All General hardware error (set if one of the H/W error flags is set)
R * All Hardware error A/D converter
R * All Hardware error D/A converter
R * All Calibration checksum error
R * All Update calibration parameters failed
Modbus® discrete input 0 is the first discrete input
A coil can be read or written.
