Slave Unit I/O information and status information is allocated in the Special I/O Unit memory area or a user-specified area of the CPU
Unit to which the Master Unit is mounted.
The area is determined by the unit number of the Master Unit as a Special I/O Unit and by the communications mode number. The user
specifies the communications mode number using the CompoNet Support Software. The bits used by Slave Units are determined by the
node address for each Slave Unit.
The relationship between communications mode numbers, the number of connected nodes, and the number of points that can be con-
trolled is described next.
Note 1. In a CompoNet Network, Word Slave Units have 16 bits per node address. Bit Slave Units have two bits allocated per node address.
