The SYSMAC BUS/2 Slave Racks use the same Expansion I/O Backplane and
Power Supply Unit as the Expansion I/O Racks, but a Remote I/O Slave Unit is
mounted instead of the I/O Interface Unit and the Slave Rack is connected from
the Remote I/O Slave Unit to a Remote I/O Master Unit on the CPU or Expansion
CPU Rack. Refer to the SYSMAC BUS/2 Remote I/O System Manual for details.
This section describes the main components that are used to construct CPU,
Expansion CPU, and Expansion I/O Racks.
Six CPU models are available, the CV500-CPU01-EV1, CV1000-CPU01-EV1,
CV2000-CPU01-EV1,
CVM1-CPU21-EV2. The following figure shows the CV1000-CPU01-EV1.

is lit.
Note The Memory Unit is built into CVM1/CV-series PCs; it is not necessary for the
user to install one, as is necessary for some C-series PCs.
The protect keyswitch write-protects the current PC Setup and user program
memory. The user program memory can also be write-protected by the using the
"Protect UM" function from the CVSS. When set to "SYSTEM PROTECT" this
switch will write-protect the entire user program memory even if only part of it is
protected using the "Protect UM" function from the CVSS.
