The proposed transfer mechanism establishes the reading of inputs and writing to outputs through bitwise
assignments (single-bit definitions) from the master side.
Outputs:
At the master side, the user would write the desired outputs’ state (using the bitwise definitions)
to pre-defined open memory registers which are copied, using a PLC code, into the 24-bit register of
MACRO I/O node 2. At the Slave side, this MACRO I/O node register is copied, using a PLC code, into
the local outputs’ registers which will reflect the user’s outputs’ desired state.
Inputs:
At the slave side, the machine’s inputs’ state is copied into first 2 x 16-bit registers of MACRO
I/O node 2. At the master side, these MACRO I/O node registers are copied, using a PLC code, into pre-
defined open memory registers (bitwise definitions) where the user can monitor the machine’s inputs’
state.
The following diagram summarizes the abovementioned transfer technique:
