Signal types
All signals accessible from a SCADA system are described further in this document. Signals with a
default value are settings that can be changed via a SCADA system. Signals without a default value
are actual values which cannot be changed using a SCADA system.
EXOL type
The EXOL type of signals:
R = Real (-3.3E38 - 3.3E38)
I = Integer (-32768 - 32767)
X = Index (0 - 255)
L = Logic (0/1)
Modbus type
The Modbus type of signals:
1 = Coil Status Register (Modbus function = 1, 5 and 15)
2 = Input Status Register (Modbus function = 2)
3 = Holding Register (Modbus function = 3, 6 and 16)
4 = Input Register (Modbus function = 4)
