The CompoNet Master Unit has 5 communications modes. When using
communications modes 0 to 3, the CompoNet Unit IN/OUT information is allocated
in the Special I/O Unit Area. When using communications mode 8 (Software Setting
Mode), the CompoNet Unit IN/OUT information can be allocated in the CIO, DM,
WR, and HR Areas, in addition to the Special I/O Unit Area.
The Software Setting Table is used in the following situations.
•
When allocating words in an area other than the Special I/O Unit Area to Slave
Units
•
When setting the number of words allocated, e.g., when words after those
allocated to the Slave Units will be used for another purpose.
In the Software Setting Mode, memory is allocated to each Word Unit and Bit Unit
for the Word IN/OUT Areas, Bit IN/OUT Areas, Participation Flags, and
Communications Error Flags.
