Configuration Limits
The following two tables indicate limits on the system configuration. The first
table indicates limits for the basic System. The second table indicates limits for
Remote I/O Systems.

Note 1. 58M Slaves are counted as one Unit and 122M and 54 MH Slaves are
counted as two Units in figuring the total of eight connectable Units. 58M,
122M, and 54MH classifications are set with a switch on the Slave.
2. A SYSMAC BUS/2 Slave must be designated “54MH” to use
READ(190)/WRIT(191) for Special I/O Units mounted to it. These instruc-
tions cannot be used for SYSMAC BUS Slaves regardless.
