4.3 Transmission Data
The data to be transferred from the SST-PN-2-PE board to the inside of
the YRC1000micro is not only the I/O data from the external device
connected to the PROFINET, but also the status of the SST-PN-2-PE
board.
Therefore, inside the YRC1000micro, 8 points (1 byte) each for input and
output are reserved for the SST-PN-2-PE board status, beside the area for
the digital data. The output area, however, cannot be used.
The transmission data from the SST-PN-2-PE board are allocated to the
external I/O signals of concurrent I/O.
Where an SST-PN-2-PE board is mounted as an optional I/O board, the
concurrent I/O allocation of the board is shown in the following table.
The I/O area: 20010 to 20017 and 30010 to 30017 is reserved for the
standard I/O board of the YRC1000micro.
When the PROFINET communication is disconnected, the
transmission data allocated for the concurrent I/O keeps the
previous value. (The value is not cleared to 0.)
However, when turning ON the YRC1000micro, the previ-
ous value is cleared to 0, not kept.
