Modules
With help of Modbus_Module's you define what type of actions you want to perform on the slave
and at which address. The action is defined by a function code which means either reading or
writing data to the Modbus slave. You also specify the address at which to read or write. The
number of data to be read or written is defined by how you define the data area (see below).
The supported function codes are:
ReadCoils (FC 1)
This function code is used to read from 1 to 2000 contiguous status of coils in a remote device.
Typically the input data area is defined by a number of ChanDi's which represent the number of
coils you want to read. The representation on the ChanDi should be set to Bit8.
ReadDiscreteInputs (FC 2)
This function code is used to read from 1 to 2000 contiguous status of discrete inputs in a remote
device. Typically the input data area is defined by a number of ChanDi's which represent the
number of coils you want to read. The representation on the ChanDi should be set to Bit8.
ReadHoldingRegisters (FC 3)
