Signals
Chapter 19 Signal types
EXOL type
The EXOL type of the 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 the signals (type in the list below):
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)
Supported Modbus functions:
1 = Read Coils
2 = Read Discrete Input
3 = Read Holding Register
4 = Read Input Register
5 = Write Single Coil
6 = Write Single Register
15 = Write Muntiple Coils
16 = Write Multiple Registers
Max 47 register
Max 47 register can be read in one message.
Communication limits
The modbus master must wait for a minimum of 3.5 charactertimes (4ms at 9600 bps)
between two messages. When the modbus master communicate with more than one
controller on the same communication line (RS485), the modbus master must wait for a
minimum of 14 charactertimes (16ms at 9600bps) between the answer and the first question
for the next controller.
In the controller there is a limit of 10 fast communications in every half minute, the other
communications will have a delayed answer of approximately 1 second.
Scale factor Modbus
All real signals have scale factor 10 except the time settings signals that have scale factor
100 for modbus communication. Integer, Index and Logic has always scale factor 1.
EXOline/Modbus
The factory setting for the Maxi controller is Modbus communication. If you try to
communicate EXOline, the controller will automatically change to EXOline communication
after the first communication attempt. 10 seconds after the last EXOline communication, the
controller will return to Modbus communication. You can also set the controller to only
communicate EXOline, via Regio tool
