3.4 Assignment of data areas 3400 Assignment of data areas 3- ModbusTCP_Coil and Register Map-Einleitung-PNOZmulti
Data can be accessed via various Modbus/TCP data areas.
The tables below show the relationship between Modbus/TCP data ar-
eas and the content of the data areas.
3.4.1 Virtual inputs
Virtual inputs 3- ModbusTCP_Datenbereiche-Virtuelle Eingänge-PNOZmulti
The table below describes the Modbus/TCP data areas that contain the
current state of the virtual inputs on the PNOZmulti. These are the virtual
inputs that can be set by the user.
Relevant areas for the data are defined in each Modbus/TCP data area
(Coils (0x), Discrete Inputs (1x), Input Register (3x), Holding Register
(4x)). Read/write access will depend on the Modbus/TCP data area.
